7.1 Regulatory authorities and port authorities

7.1.1 Acceptability of dangerous cargoes in port areas

  7.1.1.1 The regulatory authority should determine the classes and quantities of dangerous cargoes which may be permitted to transit or to enter a port area by any mode of transport and the conditions under which they are to be handled, having regard to the facilities available for the reception and keeping of dangerous cargoes and the location of the port area in relation to nearby installations and centres of population. The regulatory authority should make such information available in the national and, where appropriate, English languages.

7.1.1.1 Restrictions on the type and quantity of dangerous cargoes allowed to stay within the port area may be necessary, depending on nearby housing areas, other hazardous installations such as tank farms or chemical plants and special environmental protection areas.

When establishing quantity limitations or other restrictions, the considerations should be given to the expertise and the equipment available within the organizations responsible for emergency response (e.g., fire brigade, hospitals, and ambulance).

It is very important that those who are involved in the transport of dangerous cargoes by sea are informed about any restrictions by means of official publications (e.g., port by-laws) to avoid such dangerous cargoes arriving by ship or other means of transport and having to be rejected because of restrictions. As English is internationally accepted as the maritime language, the use of that language is recommended.

  7.1.1.2 The port authority should be empowered to refuse dangerous cargoes intended for keeping within, or transit through, the port area , if it is considered that their presence would endanger life or property because of their condition, the condition of their consignment, the condition of their mode of conveyance, or the conditions in the port area . Notwithstanding this provision all reasonable effort should be made to aid a ship in distress, particularly when the lives of its crew are in danger.

  7.1.1.3 If any dangerous cargo within the port area constitutes an unacceptable hazard, the port authority should be able to remove, or order the removal of, any such cargo or any ship , package, freight container, tank-container, portable tank, vehicle or other cargo transport unit containing it.

  7.1.1.4 An unstable substance should not be accepted unless all conditions necessary to ensure its safe transport and handling have been specified and met.

  7.1.1.5 Competent Authority approvals or exemptions should accompany all shipments when operational and/or transport requirements different to the IMDG Code have been permitted by a Competent Authority (MSC/Circ.1075).

7.1.2 Advance notification

  7.1.2.1 The regulatory authority should establish a system whereby the port authority is notified in good time, but generally not less than 24 hours in advance of the arrival of dangerous cargoes in the port area . The regulatory authority should establish and make information on the various categories and minimum quantities of such categories of dangerous cargoes for which prior notification of arrival is required. The system may enable special arrangements to be made or exemptions to be granted as appropriate for certain categories and/or quantities of dangerous cargoes , for certain modes of transport and for short voyages. This will include ships carrying dangerous cargoes which intend to transit through the port area . Where possible all dangerous goods should be manifested on FAL Form 7 as amended.

7.1.2.1 The notification serves the purpose of allowing the port authority to check if the cargoes to be handled or in transit can be accommodated without jeopardizing the port’s safety at the intended date and time, taking into account the type and quantity of cargo involved and any quantity limitations in force.

Furthermore, it allows the port authority to verify the details (such as classification, quantity, type, packing group) and to arrange any necessary corrections in advance. It may also be used to inform the emergency services well in advance of the type and quantities expected, so that they will be able to take the necessary precautions in case of a specific risk from such cargoes.

All port authorities should know where their dangerous cargoes and related documents are located. In many ports the individual advance notifications are used to create an overview of all the dangerous cargoes in the port, that is, which cargoes are located where and in what quantities. The use of electronic data processing (E.D.P.) will facilitate the keeping of such records but requires a standardized notification format.

  7.1.2.2 Advance notification should also be given when a ship or a cargo transport unit arrives under fumigation. The notification should contain the name of the fumigant and the date of application.

7.1.2.2 Reference is made to the “Recommendations on the Safe Use of Pesticides in Ships” in the Supplement to the IMDG Code. In many cases additional national health regulations have to be observed.

  7.1.2.3 The advance notification should also include any deficiency of the ship , its equipment and/or the containment of dangerous cargoes which may affect the safety in the port area or the ship .

  7.1.2.4 The regulatory authority should establish a system whereby the port authority of the port of departure is notified, in good time but generally not less than 3 hours prior to the departure of a ship, of the dangerous cargoes on board.

  7.1.2.5 The advance arrival and departure notification should be given by letter, telex, telefax, or electronic data interchange (EDI) transmission techniques such as the international forwarding and transport of dangerous goods notification (IFTDGN) or any other means acceptable to the port authority .

7.1.2.5 In accordance with the requirements of chapter VII part A regulation 4 of the SOLAS Convention and the requirements of Annex III of the MARPOL 73/78 Convention, ships shall make available, to the port State authority, a detailed stowage plan or a list of all dangerous cargoes with their stowage position on board prior to leaving the port. This serves to ensure the availability of information on dangerous cargoes on board in cases where the relevant cargo documents cannot be obtained or communication is impossible due to an accident involving the ship. It can also be used to ensure advance notification to the next port of call.

  7.1.2.6 The information which should be given is set out at annex 1.

  7.1.2.7 For dangerous cargoes arriving by sea the notification should be given by the master of the ship, the shipowner, or his agent. For dangerous cargoes arriving by road, rail or inland watercraft, advance notification should be given by the cargo interests .

7.1.3 Berthing

  7.1.3.1 The port authority should be empowered to:

  • .1 direct when and where a ship, having any dangerous cargo on board, should anchor, moor, berth or remain within the port area , taking into consideration relevant matters such as the quantity and nature of the dangerous cargo involved, the environment, the population, the weather conditions;

  • .2 direct, in an emergency, a ship having any dangerous cargoes on board to be moved within the port area , or to be removed from the port area having due regard to the safety of the ship and its crew; and

  • .3 attach such requirements to any such directions as are appropriate to local circumstances and the quantity and nature of the dangerous cargoes involved.

  7.1.3.2 The regulatory authority should require that adequate safe means of access are provided between the ship and the shore.

7.1.4 Emergency procedures

  7.1.4.1 The regulatory authority should require that appropriate emergency arrangements (plans and procedures) are made, brought to the attention of all concerned and ensure their training is appropriate and commensurate with their responsibilities. These arrangements should include:

  • .1 the provision of appropriate emergency response alarm operating points;

  • .2 procedures for notification of an incident or emergency to the appropriate emergency response services within and outside the port area ;

  • .3 procedures for notification of an incident or emergency to the port area users both on land and water;

  • .4 the provision of emergency equipment appropriate to the hazards of the dangerous cargoes to be handled;

  • .5 the formation of a local emergency response team to co-ordinate action in the case of a major emergency and to deal with any day-to-day untoward incidents such as a minor leak or spillage of dangerous cargoes ;

  • .6 co-ordinated arrangements for the release of a ship in case of an emergency; and

  • .7 arrangements to ensure adequate access/egress at all times.

7.1.4.1 Berth emergency plans should be harmonized with the port emergency plan and the emergency plans of any other relevant nearly premises. The plans should include agreed arrangements for alerting the port authority and other premises as appropriate.

The emergency plan should set out clearly how it is to be initiated, the steps to be taken to put it into practice and identify the facilities and equipment that would be available in the event of an emergency.

It is essential to ensure that communications can be maintained with the emergency services at all times during an emergency. It is therefore necessary to ensure that facilities for dealing with the media and the public are kept separate from those used to control the emergency.

The emergency plan should be distributed to all organizations and to all bodies who may be involved with it in the event of an emergency.

Port authority personnel who may be involved in putting the emergency plan into effect should be suitably instructed and trained in its operation.

Persons who may be involved in clean up measures should be aware of the limitations of their knowledge and capabilities and have clear instructions as to when to call on external sources of help.

The emergency plan should be exercised at regular intervals, e.g., at least once per year. Whilst full-scale exercises are desirable, they may only be practicable infrequently. In such circumstances, table-top exercises should be carried out at more frequent intervals.

The emergency plan should be reviewed periodically on a routine basis, as well as after each occasion that it has to be put into effect or is exercised and when changes are made in the port. Any lesson that can be learned should be incorporated in a revision of the plan.

  7.1.4.2 The regulatory authority should require the preparation and maintenance of records of the dangerous cargoes which are present in the port area for use in emergency.

7.1.4.2 The records may be prepared from the notifications required by 7.1.2.1 and 7.1.2.4, together with details of arrival and departure. The records should show the type, quantity and location of the dangerous cargoes in the port area.

The records should include:

.1 intermediate keeping within the port area for the purpose of changing the mode of transport;

.2 dangerous cargoes remaining on board in transit (see 7.2.5.1.1); and

.3 dangerous cargoes to be loaded and discharged in the port (see 7.2.5.1.2/3).

The use of electronic data processing (EDP) has the advantage of having the possibility to provide other authorities like fire brigade, port police or port health or other authorities with the same information through electronic data interchange (EDI).

Provided that the system is constantly updated and functions without disturbance, it can provide instant information to the emergency services about the type and quantities of dangerous cargoes that may be involved in an incident, immediately after the receipt of the notification. It will enable the emergency services to plan manpower and equipment deployment already on their way to the location of the incident and take all necessary precautions right away (e.g., evacuation of people, etc.) especially when the system is connected to a dangerous substances database.

The records can also be maintained manually. In such cases each shed, warehouse or area where dangerous cargoes are kept, should have a designated place (e.g., a red box) where all relevant documents of each dangerous cargo kept within the premises are placed. The location should be chosen in close co-operation with the emergency services and should be well known to them. The person responsible for the shed, warehouse or area will also be responsible for ensuring that only documents of cargoes still within the premises are kept in the designated place.

In addition to the designated places for documents a detailed plan of each shed, warehouse or area should be prepared by the port authority in close co-operation with the emergency services and the berth operator, specifying the exact location within the shed, warehouse or area where dangerous cargoes may be kept. This should specify the class(es) and the maximum quantities that may be kept there. When specifying the class(es) and quantities, due consideration should be given to the construction and the emergency equipment installed. All parties concerned should have a copy of the plans.

  7.1.4.3 The regulatory authority should require that emergency response information is available where dangerous cargoes are handled and that it is accessible at all time.

7.1.4.3 The information is intended to give the berth operator’s personnel some guidance on the first aid and first steps to be taken to limit the extent of injuries in case of an incident until the arrival of the emergency services.

The use of electronic data banks can be of great assistance, provided the authorities and operators have direct access to the information in them.

7.1.5 Fire precautions

  7.1.5.1 The regulatory authority should require that areas where certain dangerous cargoes are handled are designated as areas where smoking and other sources of ignition are prohibited and where only electrical equipment of a type safe for use in a flammable or explosive atmosphere is used.

7.1.5.1 Attention is drawn to the relevant recommendations published by the International Electrotechnical Commission.

When considering the dangers of fire and explosion that may result from the carriage of dangerous cargoes, it should be appreciated that nominally empty holds and cargo transport units may still contain residues and flammable vapours and may remain hazardous.

  7.1.5.2 The carrying out of hot work and the use of any equipment or activity which may lead to a fire or explosion hazard should be prohibited in areas where certain dangerous cargoes are handled, unless authorized by the port authority .

  7.1.5.3 In areas or spaces where a flammable or explosive atmosphere may exist or develop, electrical equipment and gas measuring equipment should be of a type safe for use in that environment.

  7.1.5.4 Fire precautions applying to individual classes of dangerous goods, and where necessary to individual substances, are recommended in sections 7.3.2, 7.3.5 to 7.3.9 and the Dangerous Goods List of the IMDG Code.

7.1.6 Environmental precautions

  7.1.6.1 The regulatory authority should require that special areas for the holding and repacking of damaged dangerous cargoes and wastes contaminated with dangerous cargoes are provided wherever necessary.

7.1.6.1 An example of a possible facility is given in the Guidance to 3.4.4.1.

Safe reserve packagings (e.g., oversize drums) as well as absorbing or binding agents, cleaning equipment, equipment for limiting the spread of liquids (e.g., drain covers, oil booms) should be readily available.

Personnel should be regularly trained in the correct and safe use of this equipment.

  7.1.6.2 The port authority should ensure that damaged packages, unit loads or cargo transport units are immediately and safely moved to the special area mentioned in 7.1.6.1. They should ensure that damaged packages, unit loads or cargo transport units do not leave the special area unless the dangerous cargoes have been properly repacked in appropriate salvage packagings and are in all respects fit and safe for further transport and handling .

7.1.7 Reporting of incidents (including security incidents)

  7.1.7.1 Any person having charge of dangerous cargoes should inform the port authority immediately of any incident relevant to such cargo that occurs within the port area which may endanger the safety or security of persons, of the ship or of other ships within the port, of the port or of any other property or the environment.

7.1.7.1 To ensure a prompt and effective response, treatment of injured personnel and mitigation of damage, it is essential that a concise and accurate description of the incident is available to the emergency response centre as quickly as possible. If immediately available, the description should include such details as:

.1 nature and time of the incident;

.2 precise location;

.3 type, quantity and condition of cargo involved;

.4 particular hazards present/marine pollutant;

.5 details of marks and labels;

.6 if an IMDG Code classified cargo, Proper Shipping Name, class (when assigned, the division of the goods and the compatibility group letter for class 1), UN number, and packing group;

.7 name of manufacturer of the cargo;

.8 extent of damage/pollution;

.9 sequence of events leading to the incident;

.10 number and types of injuries/fatalities; and

.11 emergency response taken.

The information contained in the notification referred to in 7.1.2.1 or kept in the places mentioned in the 7.2.5.1 and in the guidance to 7.1.4.2 may be of assistance.

7.1.8 Inspections

  7.1.8.1 The port authority should make regular inspections to ensure the implementation of the safety precautions in the port area and the safe transport and handling of dangerous cargoes . They should be empowered to:

  • .1 inspect documents and certificates concerning the safe transport, handling, packing, stowage and segregation (when appropriate) of dangerous cargoes in the port area ;

  • .2 inspect packages, unit loads and cargo transport units containing dangerous cargoes to verify that they are packed, marked, labelled or placarded in accordance with the provisions of the IMDG Code or the appropriate national or international standards applicable for the mode of transport; that unnecessary labels, placards and marks have been removed; and that the cargo transport units have been loaded, packed and secured in accordance with the IMO/ILO UN ECE Guidelines for packing of cargo transport units;

  • .3 inspect freight containers, tank-containers, portable tanks and vehicles containing dangerous cargoes to ensure that they have a current safety approval plate in accordance with the International Convention for Safe Containers (CSC), 1972, as amended, when applicable, and are in compliance with the applicable provisions of part 4 and part 6 of the IMDG Code; and

  • .4 check, by external examination, the physical condition of each freight container, tank-container, portable tank or vehicle containing dangerous cargoes for obvious damage affecting its strength or packaging integrity and for the presence of any sign of leakage of contents.

7.1.8.1 For ships carrying bulk liquids reference should be made to 9.1.1.3.

The regular inspections should be carried out by especially trained personnel of the port authority. When selecting cargoes for inspection, the ones most likely to pose a risk (for example consolidated containers) should be chosen, unless there is a special action programme aimed at specific cargoes.

When carrying out inspections, care should be taken to ensure minimum disturbance of operations. Delays due to inspections should be avoided unless cargoes or cargo transport units are detained for safety or security reasons.

It is recommended that the berth operator and the cargo interests are informed about the intended inspections and that the latter be requested to participate in the inspections. This ensures that no claims of pilferage or damage to cargo can be levied against the inspection team.

It also gives the cargo interests the possibility to see at first hand any deficiency and enables them to report the findings to the originator, who in turn will then be able to check and rectify his procedures to avoid future deficiencies.

  7.1.8.2 If any of the inspections or checks mentioned above reveal deficiencies which may affect the safe transport or handling of dangerous cargoes , the port authority should immediately advise all parties concerned and request them to rectify all deficiencies prior to any further transport or handling of the dangerous cargoes .

Such inspections may also be carried out by the berth operator (see 7.3.12.1).

7.1.9 Hot work and other repair or maintenance work

  7.1.9.1 The port authority should require that it is notified of any person’s intention to carry out hot work or any other repair or maintenance work, either on board a ship or ashore, which may constitute a hazard because of the presence of dangerous cargoes , and such work is authorized only when it can be carried out without creating such a hazard.

7.1.9.1 The requirement for an authorization and advance notice of the intended period of hot work enables all emergency response institutions, such as the fire brigade, to be given adequate notice so they can voice objections or advise additional precautionary measures.

In special cases, such as hot work in holds of tankers or in or nearby enclosed spaces, a thorough inspection of the area should be conducted by specialists who can determine whether specific safety measures are required.

  7.1.9.2 In the case of hot work in or near tanks, a gas-free certificate, issued by a chemist or other suitably qualified person approved by the port authority should be pre-requisite. This certificate should be renewed if circumstances alter and at least every 24 hours.

  7.1.9.3 Hot work should only be carried out by persons approved by the port authority and only after being authorized as required in 7.1.5.2. When carrying out such work all necessary precautions should be taken.

  7.1.9.4 Minimum safety requirements for carrying out hot work are set out in annex 4.

7.1.10 Entry into confined or enclosed spaces

  7.1.10.1 The port authority should require the master of a ship and the berth operator within their respective areas of responsibility to ensure that before any personnel enter any confined or enclosed space, appropriate precautions are taken against the possible presence of dangerous vapours or oxygen depletion.

7.1.11 Cargoes and cargo transport units under fumigation

  7.1.11.1 The port authority should designate specific areas for ships or cargo transport units which arrive under fumigation or are to be fumigated. Entry into such areas should be restricted. Appropriate signs (preferably pictograms similar to that shown in figure 5) should be displayed in such areas ashore.

7.1.11.1 For containers under fumigation, reference should be made to the Recommendations on the Safe Use of Pesticides in Ships and IMO/ILO/UN ECE Guidelines for Packing of Cargo Transport Units (CTUs) in the Supplement to the IMDG Code. Such containers shall also carry the fumigation warning sign. In many cases additional national legal requirements relating to health should be observed.

Annex 3 of the Recommendations on the Safe Use of Pesticides in Ships shows a warning sign to be used for ships, ships’ compartments, freight containers, barges and cargo transport units under fumigation. A similar label is shown in annex 2 of the IMO/ILO/UN ECE Guidelines for Packing of Cargo Transport Units (CTUs).

Figure 5 of these Recommendations shows an example of a pictorial warning sign suitable for cargo sheds, other spaces ashore which are fumigated or about to be fumigated or in which cargo transport units under fumigation are kept. The sign should be of an appropriate size to be clearly seen.

Figure 5 Fumigation warning sign

  7.1.11.2 No unauthorized persons should be allowed access to ships, warehouses, sheds or cargo transport units until all parts of such ships, warehouses, sheds or cargo transport units have been determined gas-free, fumigation warning signs have been removed and a clearance certificate issued by a responsible person .

  7.1.11.3 Prior to giving permission for access to ships, warehouses, sheds or cargo transport units under fumigation, the port authority should require a clearance certificate from a responsible person that it is safe to do so.

  7.1.11.4 No person should fumigate the contents of a freight container, barge or cargo transport unit once it has been loaded on board a ship.

  7.1.11.5 A Guide to fumigation operations is set out in annex 7.

7.1.12 Reception facilities for contaminated bilge water, wastes, ballast and slops

  7.1.12.1 The regulatory authority should make the necessary legal requirements to ensure that, where necessary, contaminated bilge water and hazardous wastes are removed from the ship prior to leaving the port area .

7.1.12.1 Reference should be made to the MARPOL 73/78 Convention and the IMO Comprehensive Manual on Port Reception Facilities for additional information and guidance.

  7.1.12.2 The regulatory authority should ensure that adequate reception facilities are provided for the reception and disposal of bilge water, wastes, ballast and slops contaminated with dangerous cargoes , as appropriate.

  7.1.12.3 The regulatory authority should ensure that the legal requirements for bunkering (7.1.14) are also applied to reception operations.

7.1.13 Safe transport and handling

  7.1.13.1 The regulatory authority should establish guidelines for measures to be taken to ensure the safe transport and handling of dangerous cargoes , especially the packing, stowage and segregation of incompatible cargoes in compliance with the requirements of part 4 and part 7 of the IMDG Code.

  7.1.13.2 Where the handling of dangerous cargoes involves the temporary keeping of the cargoes in the port area for the purpose of changing the mode of transport, requirements similar to those described in chapter 7.1 and 7.2 of the IMDG Code should be adopted for the stowage and segregation in the port area.

7.1.13.2 An example of general guidance on stowage and segregation of dangerous cargoes is shown in table 1 however, divergence from these guidelines may be appropriate. In a remote area, less stringent regulations may be acceptable. If a port is sited in the vicinity of housing areas, chemical plants or tank farms for example, it may be necessary to impose more stringent stowage and segregation requirements.

In all cases, all interested parties should be informed of the required standard by port by-laws and other publications to avoid any problems in day-to-day operation.

7.1.14 Bunkering

  7.1.14.1 The regulatory authority and port authority should include legal requirements for bunkering in port laws or port by-laws which should include the use of a bunkering checklist reflecting local circumstances. Bunkering of ships should normally only be allowed at designated installations or by using bunker vessels. Bunkering precautions including a bunkering checklist are set out in annex 5.

  7.1.14.2 Where bunkering is carried out simultaneously with the handling of dangerous cargoes , gas freeing, purging or tank cleaning, the port authority may consider the need for special permission to be given and special precautions to be taken to avoid damage to connecting pipelines or flexible pipes or any other damage. The permission should only be given when all the questions contained in the bunkering checklist have been answered affirmatively.

  7.1.14.3 Dangerous cargoes of class 1 (except those in division 1.4S) and bulk cargoes of class 5.1 should not be loaded or unloaded when bunkering is in progress unless permission has been granted by the port authority and under conditions prescribed by the port authority.

Note Cargoes of classes 1 (except division 1.4S), 6.2 and 7 should normally be allowed into the port area for direct shipment or delivery only. These classes have not been included in the table. However, if, through unforeseen circumstances, these cargoes have to be temporarily kept, it should be in designated areas. Segregation requirements of the individual class as stipulated in the IMDG Code should be considered by the port authority when establishing specific requirements.

Note to Table 1Segregation Advice for The Temporary Keeping of Dangerous Cargoes in Port Areas

  1 The reception and keeping of dangerous cargoes of classes 1 (other than division 1.4S), 6.2 and 7 should be subject to special rules for each port as the handling facilities at each terminal or berth vary considerably. The rules should be agreed with the authorities responsible for the safety of the port.

  2 All dangerous cargoes delivered to the port area should be marked, documented, packaged, labelled or placarded in accordance with the IMDG Code.

  3 The segregation of dangerous cargoes should be in accordance with chapter 7.2 of the IMDG Code as follows:

  3.1 Packages/IBCs/trailers/flat racks or platform containers

0 = no segregation necessary unless required by the individual schedules
a = away from – minimum 3 m separation required
s = separated from – in open areas, minimum 6 m separation required in sheds or warehouses, minimum 12 m separation required unless separated by an approved fire wall

  3.2 Closed containers/portable tanks/closed road vehicles

0 = no segregation necessary
a = away from – no segregation necessary
s = separated from – in open areas, longitudinally and laterally, minimum 3 m separation required, in sheds or warehouses longitudinally and laterally, minimum 6 m separation required unless separated by an approved fire wall

  3.3 Open road vehicles/railway freight wagons/open-top containers

0 = no segregation necessary
a = away from – minimum 3 m separation required
s = separated from – in open areas, longitudinally and laterally, minimum 6 m separation required, in sheds or warehouses longitudinally and laterally, minimum 12 m separation required unless separated by an approved fire wall

Note 1 For freight containers, portable tanks, lorries, flat racks or platform containers or rail wagons a distance of 3 m is equal to the width of a standard 20-foot container, or one rail track, one trailer lane or, in the case of successive rail wagons, the longitudinal buffer space.

Note 2 The segregation table shown uses “0” to indicate that no general segregation is required but those individual requirements of the Dangerous Goods List of the IMDG Code shall be consulted. The IMDG Code’s general segregation table (7.2.1.16), however, uses an “X” instead of the “0” used in these Recommendations. The difference is intentional, to emphasize the difference in the use of the segregation tables.

Note 3 “Closed type unit” means a unit in which dangerous goods are totally enclosed by sufficiently strong boundaries, such as a freight container, a tank or a vehicle. Units with fabric sides or tops are not closed type units.

Note 4 General

Note 4.1 For dangerous cargoes with a secondary hazard, the segregation requirement for the secondary hazard should be applied when it is the more stringent. For cargo transport units containing dangerous cargoes of more than one class, the most stringent segregation requirement should be applied.

Note 4.2 Dangerous cargoes in packaged non-containerized form, belonging to different classes, should not be stowed directly above each other. This applies to packaged dangerous cargoes belonging to one class but having different secondary hazards and also to certain cargoes of class 8.

Note 4.3 Containers, tank-containers and portable tanks containing dangerous cargoes, where practicable, should not be stowed directly above each other or overlap. Exemptions should only be allowed for containers which contain dangerous cargoes of the same class. This does not apply to containers with different cargoes of class 8. Where applicable, containers should be stowed in such a manner as to allow, when applicable, access to the doors and both sides at all times.

Note 4.4 Dangerous cargoes with toxic (poisonous) labels or placards should be separated from foodstuffs and animal feeds.

Note 4.5 The segregation requirements only apply to dangerous cargoes in storage areas and on vehicles in the port areas.

Note 4.6 All dangerous cargoes, except for individual packages, should, where applicable, be separated by a minimum distance of 1 m in order to permit access.

7.1.15 Explosives

  7.1.15.1 Dangerous cargoes of class 1 other than division 1.4S should only be permitted to enter the port area for direct shipment to or from ships , unless permitted by the regulatory authority .

  7.1.15.2 The regulatory authority should establish specific requirements for the transport and handling of explosives , having regard to the hazards involved and the population density in the vicinity of the port area and any other relevant circumstances.

  7.1.15.3 The regulatory authority establishing these specific requirements should highlight the fact that the classification of explosive substances and articles, together with the compatibility group assignment and the Proper Shipping Name, under which the substance or article is to be transported, shall have approval by the competent authority of the country of manufacture prior to transport in compliance with the provisions of chapter 2.1 of the IMDG Code.

  7.1.15.4 The following precautions during loading and unloading of explosives should be taken into account:

  • .1 Artificial lighting

    Electric lights, except arc lights, are the only form of artificial lighting permitted during cargo operations involving dangerous goods of class 1 (requirements for electrical equipment and cables are set out in chapter 7.1 of the IMDG Code);

  • .2 Radio and radar

    During loading or unloading of cargoes of class 1 (except those in division 1.4), no radio or radar transmitters should be used on the ship, in cranes or elsewhere in the vicinity, except for VHF transmitters with a power output that does not exceed 25 W and no part of their aerial systems passes within the minimum safe distance of 2 metres from the explosives.

    Some articles of class 1 contain initiation systems which are sensitive to electromagnetic radiation from external sources such as radio or radar transmitters. Therefore all such equipment should be de-energized by opening the main switches controlling the equipment and tagging them to ensure that the devices are not energized until loading or unloading has ceased.

  • .3 Mechanical aids to stowage

    All mechanical aids to stowage, whether power-driven or not, should be properly maintained and inspected before use to ensure that they are in a good working condition, comply with an appropriate recognized standard and are serviced in accordance with the manufacturer’s maintenance recommendations.

  • .4 Defective packages

    Any damaged, leaking, affected by moisture or otherwise defective package should not be accepted for shipment. No repair of defective or damaged packages should be permitted on board the ship.

  • .5 Protections against weather

    Packages containing dangerous goods of class 1 should be prevented from becoming wetted since, the danger may, in some cases, be aggravated by wetting.

  • .6 Security

    To ensure the security of dangerous goods of class 1, a responsible person should be present at all times whilst the hatches are open. Unauthorized persons should never be allowed access to compartments where goods of class 1 are stowed.

  7.1.15.5 Basic items for consideration by the regulatory authority are set out at annex 2.

7.1.16 Radioactive material

  7.1.16.1 Radioactive material, assigned to class 7 of the IMDG Code and described in chapter 2.7 of the Code, should only be permitted to enter the port area for direct shipment or delivery if permitted by the regulatory authority .

7.1.16.1 When radioactive material cannot directly go to or from a ship for unforeseen reasons it should only be kept in port areas with the permission of the regulatory authority.

  7.1.16.2 Packaged radioactive material should not be brought into the port area unless it is in conformity with the International Atomic Energy Agency’s (IAEA) Regulations for the Safe Transport of Radioactive Materials, and the requirements of the IMDG Code or similar national legal requirements.

  7.1.16.3 Packages containing radioactive material should be stowed and segregated in compliance with the detailed requirements of sections 7.1.14 and 7.2.9 of the IMDG Code. Guidance on segregation distances required on shore is set out in annex 3.

  7.1.16.4 In the event of any accident involving radioactive material or packages of radioactive materials or any theft or loss of any such materials or packages, the port authority and relevant national authorities should be notified immediately. If there is any possibility of loss of containment of radioactive material, the area should be isolated and the appropriate contingency plans put into operation.

7.1.17 Infectious substances

  7.1.17.1 Infectious substances (class 6.2 of the IMDG Code) should only be permitted to enter the port area for direct shipment or delivery if permitted by the regulatory authority .

7.1.17.1 When infectious substances cannot directly go to or from a ship for unforeseen reasons they should only be kept in port areas with the permission of the regulatory authorities.

  7.1.17.2 The regulatory authority should establish specific requirements for the handling of infectious substances, including but not limited to:

  • .1 areas for handling ;

  • .2 stringent supervision; and

  • .3 additional equipment for the containment of such substances.

7.1.18 Signals

  7.1.18.1 The regulatory authority should decide if and when a ship engaged in the transport or handling of certain specified dangerous cargoes in the port area , should exhibit by day or by night any special visual signals.

  7.1.18.2 The specified dangerous cargoes referred to in 7.1.18.1 should include:

  • .1 bulk liquids with a flashpoint below 60ºC closed cup;

  • .2 bulk flammable and/or toxic gases; and

  • .3 explosives (other than division 1.4S), liquid desensitized explosives assigned to class 3 and solid desensitized explosives assigned to class 4.1; to the degree specified by the regulatory authority .

7.1.18.2 The reason for exhibiting a day or night signal is to advise maritime traffic and personnel within the port area about an increased hazard created by the presence of the dangerous cargoes listed in 7.1.18.2. Vessels exhibiting such signals may be subject to the special requirements and special instructions of the port authority.

  7.1.18.3 The following four scenarios should be considered:

  • .1 the ship is moored or at anchor by day;

  • .2 the ship is moored or at anchor at night;

  • .3 the ship is under way by day; or

  • .4 the ship is under way at night.

7.1.18.3 When practicable, a dedicated anchorage or berth should be provided for vessels carrying dangerous cargoes listed in 7.1.18.2 requiring the exhibition of such signals. Special restrictions may be applied to:

.1 access to the vessels;

.2 radio and radar transmissions;

.3 transiting the anchorage; and

.4 passing of ships moored or anchored.

Port authorities should give consideration to the separation of ships under way exhibiting the signals required by 7.1.18.1. The port authority may also impose specific separation distances and regulate the movement of vessels to avoid the passing of such ships in narrow channels or at bends.

  7.1.18.4 Where signals are to be exhibited, they should be:

  • .1 by day flag “B” of the International Code of Signals; and

  • .2 by night an all-round fixed red light.

7.1.19 Communications

  7.1.19.1 The port authority should ensure that every ship engaged in the transport of dangerous cargoes can maintain effective communications with the port authority . When appropriate and practicable such communications should be carried out by VHF in accordance with the provisions of SOLAS regulation IV/7 and complying with the performance standards set out in IMO Assembly resolution A.609(15) and the requirements of the regulatory authority .

7.1.19.1 Effective communications are a prerequisite for the safety of the ship and its crew as well as for the port, its employees, installations and the environment. They are necessary for the exchange of the important information, such as the safety of navigation, waiting and berthing orders, and notification or reporting of incidents.

For ships entering and leaving the port, reporting locations should be established. Furthermore, ships should be requested to maintain constant watch on pre-assigned radio channels while within the port area. The reporting points and listening channels should be published in the port by-laws, port or terminal information books and hydrographical publications, for example the World Vessel Traffic Service Guide.

It may also be necessary to require ships carrying certain dangerous cargoes to take a suitable telephone on board while alongside (see Guidance to 7.2.1.2.1).

7.1.20 Pilotage and tug assistance

  7.1.20.1 The port authority should decide if and when a ship engaged in the transport of dangerous cargoes should take a pilot on board and/or tug assistance while entering, leaving or moving in the port area.

  7.1.20.2 In making such decision consideration should be given to:

  • .1 the type of ship and its manoeuvrability;

  • .2 the traffic situation;

  • .3 the layout of the port area ;

  • .4 the tidal and weather situation; and

  • .5 the categories (classes) and quantities of dangerous cargoes carried.

7.1.21 Unmanned barges

  7.1.21.1 The regulatory authority should establish specific rules for unmanned barges carrying dangerous cargoes , including but not limited to:

  • .1 handling of such barges;

  • .2 waiting areas;

  • .3 watchkeeping; and

  • .4 fire precautions and fire-fighting arrangements.

7.1.21.1 Unmanned barges carrying dangerous cargoes should be moored in designated areas where adequate access to emergency facilities such as fire-fighting monitors, fire-fighting boats or tug assistance is available. A shore-based watchman should safeguard the barges. He should be provided with adequate means of communication.

7.1.22 Exemptions

  7.1.22.1 The regulatory authority should take account of the varying degrees of hazards presented by dangerous cargoes and provide for exemptions from the provisions of these Recommendations, as appropriate. Exemptions should take account of nature, class and amount of the dangerous cargoes involved and the specific circumstances of the port area . In all cases it should be ensured that the exemption will not give rise to a significant risk to persons.

7.1.23 Knowledge of rules an regulations

  7.1.23.1 The port authority should appoint at least one responsible person who has adequate knowledge of the current national and international legal requirements concerning the transport and handling of dangerous cargoes .

7.1.24 References

  7.1.24.1 The port authority and terminal operators should ensure that all relevant national and international legal requirements, guidelines, recommendations or other documents governing, referring or relating to:

  • .1 the transport of dangerous cargoes ;

  • .2 ships carrying such cargoes; and

  • .3 installations handling , transporting, producing or otherwise using such cargoes;

which have to be consulted within the port area , are readily available at the port authority for reference and are updated as appropriate.
