Regulation II-2/5.2.1.1 – Closing Appliances and Stopping Devices of Ventilation

  1 Battery room ventilators should be fitted with a means of closing whenever:

  • .1 the battery room does not open directly onto an exposed deck;

  • .2 the ventilation opening for the battery room is required to be fitted with a closing device according to the Load Line Convention (i.e. the height of the opening does not extend to more than 4.5 m (14.8 feet) above the deck for position 1 or to more than 2.3 m (7.5 feet) above the deck in position 2; or

  • .3 the battery room is fitted with a fixed gas fire-extinguishing system.

  2 Where a battery room ventilator is fitted with a closing device, then a warning notice stating, for example "This closing device is to be kept open and only closed in the event of fire or other emergency – Explosive gas", should be provided at the closing device to mitigate the possibility of inadvertent closing.
