6.2 Occupational health

  6.2.1 Engine-rooms should be designed to comply with resolution A.468(XII) - Code on Noise Levels on Board Ships.

  6.2.2 Engine-rooms should be designed to comply with ISO 8861, Engine-room ventilation in diesel-engined ships - Design requirements and basis of calculations, and ISO 8862 - Air-conditioning and ventilation of machinery control-rooms on board ships - Design conditions and basis of calculations. Due to the hazards to health caused by exposure to oil and inhalation of oil mist, all practicable means should be taken to avoid unnecessary exposure and special consideration should be given to the installation, location and ventilation of equipment likely to produce oil vapour and mist.

  6.2.3 Enclosed control rooms, when provided, should be air conditioned to provide periodic relief from high temperatures in engine-rooms as well as to optimize the performance of electrical and electronic circuits. Other areas of engine rooms should be provided with heating or cooling facilities, as necessary, to ensure the temperature does not adversely affect the performance of personnel working in them during watchkeeping, maintenance or repairs.

  6.2.4 Lighting should be adequate for the tasks of personnel working in engine rooms and associated spaces. The minimum illumination levels should be determined by the Administration, taking into account national or international standards recognized by it. In the absence of such standards, the Administration should be guided by the table given below. Adequate lighting below floor plates should also be considered.

  6.2.5 Machinery mountings in engine-rooms should be designed so as to minimize machinery vibration and long-term effects of vibration on personnel working in the engine-room.
