Regulation II-2/19.3.4 – Ventilation

  1 If adjacent spaces are not separated from cargo spaces by gastight bulkheads or decks, then they should be considered as part of the enclosed cargo space and the ventilation requirements should apply to the adjacent space as for the enclosed cargo space itself.

  2 Where the IMSBC Code requires:

  • .1 two (2) fans per hold, a common ventilation system with 2 fans connected is acceptable; and

  • .2 continuous ventilation, this does not prohibit ventilators from being fitted with a means of closure as required for fire protection purposes under SOLAS regulation II-2/5.2.1.1, provided the minimum height to the ventilator opening is to be in accordance with regulation 19.3 of the 1966 International Convention on Load Lines (4.5 m for position 1 and 2.3 m for position 2).
