areas under floor plates where oil pipes are located should be painted a light colour.
       any light that fails should be replaced as soon as possible;
       temporary or portable lighting should be used to provide additional illumination as required, and should be removed immediately after use.
Ventilation should be maintained to ensure a comfortable atmosphere so far as is reasonably practicable in all areas, with special attention being given to working areas and control rooms. If necessary, ventilation should be increased where maintenance and repair work is to be carried out in areas of high temperature or high humidity.
Unless properly equipped and authorised to be operated without persons in attendance, the boiler room and machinery space should be under the direct supervision of an engineer officer at all times.
All work on piping systems should be performed under the supervision of an engineer officer and the following precautions should be taken:
       all drains on equipment such as pipes and filters should be kept clear;
       ensure that any pressure has been relieved in all relevant piping, system or container before it is opened or any flange or joint is broken, noting that valves may not be completely tight nor lines fully drained and that pressure, or accumulation of oil and scalding water, may build up in a pipe even after the pressure has been relieved;
       as a precaution, bolts should be only slackened back and not removed until the flange or joint is broken;
       if the flange or joint does not part easily, separation should be made with a wedge and not by allowing pressure into the line. The pipe should be secured temporarily if necessary before the flange or joint is broken;
       any valve controlling flow should be effectively locked or secured as long as the line remains open and, if necessary, a warning notice should be posted.
All stores and tools should be properly stowed and adequate arrangements should be made in preparation for heavy weather.
When lifting weights, seafarers should avoid strains by using chain blocks or the engine room crane, as appropriate. When turning valves or hand wheels, seafarers should avoid strains by using lever or wheel spanners.
Where heavy items are lifted by chain blocks or by an engine room crane:
       the lifting device and lifting arrangements should be examined by the responsible engineer officer, who should ensure that the safe working load is not exceeded;
       slings should be examined for broken or ragged strands, and padded if necessary to avoid damage on sharp edges.
When working alone, a person should arrange to communicate at regular and frequent intervals with other persons in the machinery spaces
