when the ship is working in a seaway.
Water should not be used to cool cargoes that may liquefy.
The appropriate national and international requirements with respect to ventilation should be followed. Certain cargoes, such as some coals, copra, swarf, charcoal and concentrates are liable to self-heating and may catch fire if the temperature is high enough. Cooling such material should be carried out with extreme care since water used to cool the cargo may actually increase heating and lead to spontaneous ignition and/or explosion. The temperature of holds containing such cargo should be checked daily or in accordance with the operator's or shipper's instructions.
The dust from some bulk cargoes including grain and sugar dusts can be explosive. Particularly when cleaning holds after discharge, seafarers should be made aware of this hazard. Smoking should be prohibited and cleaning carried out to minimise dust formation, for example, by hosing down. Static electricity is a major source of hazard and care must be taken to ensure that equipment used is suitable for controlling static hazards.
Seafarers and other personnel should not enter wing tanks when grain is being loaded.
Ensure equipment used for loading and unloading dry bulk, including conveyors, are fit for purpose, maintained and inspected as required.

22.2 RO-ROS and vehicle and passenger ferries
Operators must provide seafarers with training, especially in the operation and maintenance of ramps and vehicle access doors.
The cargo securing manual should be kept readily accessible. The movement, stowage and securing of vehicles on vehicle decks and ramps should be supervised by a responsible ship's officer.
Special attention should be paid to the possible ingress of water, for example, through defective door closures, scuppers, broken bilge pipes and faulty bilge non-return valves, which may affect the stability of the ship. Any water that does enter should be reported to the bridge immediately. The officer of the watch should arrange for the water to be pumped out as soon as possible and the cause of the inflow investigated and remedied.
The person in command should ensure that an effective system of supervision and reporting of the closing and opening of doors and ramps is in operation. Doors should never be opened when the ship is under way. Openings in the deck must be suitably framed.
The appropriate gas detection instruments must be carried on board to ensure ro-ro spaces are safe (refer to section 7).
The advice given in operating manuals should be followed when opening, working, closing, locking and maintaining cargo access equipment.
There should be no unauthorised persons on vehicle decks at any time, and there should be no entry to vehicle decks when the vessel is at sea, unless specifically permitted.
