Regulation 8

An adequate system of heating the crew accommodation shall be provided except in ships engaged exclusively in voyages in the tropics or the Persian Gulf.

The heating system shall, when practicable, be in operation at all times when the crew is living or working on board and when conditions require its use.

In any ship in which a heating system is required, the heating shall be by means of steam, hot water, warm air or electricity, except that in new MLC ships heating shall not be by means of steam in any crew accommodation area.

In any ship in which heating is provided by a stove, measures shall be taken to ensure that the stove is of sufficient size and is properly installed and guarded and that the air is not fouled.

The heating system shall be capable of maintaining the temperature in crew accommodation at a satisfactory level under normal conditions of weather and climate likely to be met with on service. Heat load calculations shall be submitted to the Director or an authorised organisation for approval to show that the heating system is capable of ensuring that the temperature in crew accommodation can be maintained at 21 °C when the ventilation system provided for those rooms is working so as to supply at least 25 m3 of fresh air per hour for each person for whom that room is designed and when the ambient temperature is -1 °C.

Radiators and other heating apparatus shall be so placed and, where necessary, shielded as to avoid risk of fire or danger or discomfort to the occupants.
