FLAMMABLE LIQUIDS, FLOATING ON WATER

General comments Avoid sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools). Liquid is flammable and spillage may evolve flammable vapours.

Wear suitable protective clothing and self-contained breathing apparatus. Stop leak if practicable.

In general, substances covered under this schedule will have fuel-oil-like properties. They are immiscible with water and are liable to float on the surface of water. The use of inert absorbent material, as used in machinery spaces, is appropriate in all cases. For sticky liquids, shovels may be used, preferably shovels made of non-sparking or non-ferrous material.

You may use light oil or soap-like products (surfactants) to clean small areas. Clean the area thoroughly because of the flammability hazard.

Any pumping of spilled liquid overboard will create an oil spill on the sea surface. In this case, contact coastal authorities.

Report discharge overboard according to MARPOL reporting requirements.

RADIOACTIVE MATERIAL

General comments Evacuate compartment or downwind area of non-essential personnel.

Provide respiratory protection to personnel in downwind area.

For ships carrying radiation monitoring equipment, measure radiation levels. In this case, assess the extent of contamination and resultant radiation level of the package, the adjacent areas and, if necessary, all other material which has been carried in the conveyance.

Define a zone for restricted entry. Personnel should not enter this zone without suitable protective clothing and self-contained breathing apparatus.

Limit entry of personnel to the restricted zone for the shortest time possible.

Cover liquid spill with inert absorbent materials, if available. Cover powder spills with plastic sheet or tarpaulin to minimize spread.

If exposure of personnel is suspected, clean body and hair with warm water and soap; discharge resultant washings directly overboard.

Record the names of potentially exposed persons. Ensure medical examination of these persons after reaching any medical staff.

Emergency procedures, if established for the ship or the specific cargo by relevant authorities or the shipper, should be followed.

For ships carrying radiation monitoring equipment, continue monitoring the radiation levels. Radio for expert ADVICE.

Spillage on deck Packages

(small spillage)

Wash spillages overboard with copious quantities of water. Keep clear of effluent.

Packages damaged or leaking radioactive contents may be removed to an acceptable restricted access interim location. Isolate and sheet over. Do not remove packages from restricted access zone until approved by the competent authority.

Special cases:  
UN 2977, UN 2978, UN 3507 Avoid contact, even when wearing protective clothing. Keep clear of evolving vapours. Even short-time inhalation of small quantities of vapour can cause breathing difficulties.

Bear in mind that gases are heavier than air. Measures should be taken to prevent leaking gases from penetrating into any other part of the ship.

Keep bridge and living quarters upwind. Protect crew and living quarters against corrosive and toxic vapours by using water spray to drive vapours away.

Do not enter space without protective equipment. Keep clear. Radio for expert ADVICE.

GASES (FLAMMABLE, TOXIC OR CORROSIVE)

General comments Spaces and areas where leakages or spillages have occurred should be evacuated downwind immediately.

Take care: Flames may be invisible. Leaking gas may be extremely cold.

Measures should be taken to prevent leaking gases from penetrating into any other part of the ship. Bear in mind that some gases are heavier than air or may otherwise accumulate in lower or non-ventilated parts of the ship. Ensure that there is no smoking or any other open fire on board unless the leak has been closed and all spaces have been ventilated. Particular attention should be taken in order to prevent gases drifting into occupied areas of the ship, e.g. living quarters, machinery spaces, working areas.

Wear protective clothing suitable for gas protection and self-contained breathing apparatus.

Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools, friction). Wear non-sparking footwear.

Even short inhalation of small quantities of gas can cause breathing difficulties. Keep clear of evolving gases. Avoid all skin contact.

Let spilt liquefied gas evaporate. When in contact with cold liquefied gases, most materials become brittle and are likely to break without warning. Avoid all contact, even when wearing protective clothing. If practicable, protect ship's superstructure with copious quantities of water. Do not direct water jet onto the spill.

Spillage on deck Packages

(small spillage)

Let gas dissipate. Keep clear.
Cargo transport units (large spillage) Let gas dissipate. Keep bridge and living quarters upwind.

Otherwise, protect crew and living quarters against flammable or toxic gases by using water spray to drive gases away (water curtain).

Spilt liquefied gas: Use water jets from as far as practicable to accelerate evaporation, not directing them straight onto the spill.

GASES (NON-FLAMMABLE, NON-TOXIC)

General comments Measures should be taken to prevent leaking gases from penetrating into any other part of the ship. Bear in mind that some gases are heavier than air or may otherwise accumulate in lower or non-ventilated parts of the ship. Particular attention should be taken in order to prevent gases drifting into occupied areas of the ship, e.g. living quarters, machinery spaces, working areas. Leaking gas may be extremely cold.

Wear suitable protective clothing and self-contained breathing apparatus (suffocation hazard).

Let spilt liquefied gas evaporate. When in contact with cold liquefied gases, most materials become brittle and are likely to break without warning.

OXIDIZING GASES

General comments Areas containing leakages or spillages should be evacuated downwind immediately. These gases may ignite combustible material and enhance fire.

Take care: Flames may be invisible. Leaking gas may be extremely cold.

Measures should be taken to prevent leaking gases from penetrating into any other part of the ship.

Ensure that there is no smoking or any other open fire on board unless the leak has been closed and all spaces have been ventilated. Particular attention should be taken in order to prevent gases drifting into occupied areas of the vessel, e.g. living quarters, machinery spaces, working areas.

Wear suitable protective clothing and self-contained breathing apparatus.

Avoid all sources of ignition (e.g. naked lights, unprotected light bulbs, electric handtools, friction). Wear non-sparking footwear.

Even short inhalation of small quantities of gas can cause breathing difficulties. Keep clear of evolving gases. Avoid all skin contact.

Electrostatic hazard: Electric charge may ignite ammunition. Keep spilled material away from generators of static electricity (e.g. mobile phones, friction of synthetic polymers like PVC gloves). Wear non-sparking footwear.

Some explosive mixtures are stabilized in such a way that water will separate explosives from the stabilizer, thus creating a higher risk. The explosive component becomes very sensitive to shock and heat.
