There are two health programs with which you will be directly involved in day-to-day operations in the engine room: heat stress and hearing conservation.

HEAT STRESS

Heat stress is caused by high heat and humidity. This can be controlled somewhat by ensuring that all lagging and insulation is in its proper place, that steam and hot water leaks are corrected as soon as possible, and that all the ventilation systems are operating as designed. There are other measures that you can take to help reduce heat stress. You can ensure that readings are taken and recorded at each watch or work station every hour and at any other time that the temperature exceeds 100F dry-bulb temperature. You can ensure that they are reported to the engineering officer of the watch (EOOW) so that a heat survey can be conducted and corrective action can be taken.

HEARING CONSERVATION

The loud, high-pitched noise produced by an operating propulsion plant can cause hearing loss. A hearing loss can seldom be restored. For this reason, ear protection must be worn in all areas where the sound level is 85 dB or greater. In these places, warning signs must be posted cautioning about noise hazards that may cause loss of hearing.

For further information on health programs, refer to the Naval Occupational Safety and Health Program Manual, OPNAVINST 5100.19 (latest edition).

SUMMARY

In this chapter, we have discussed the Engine-man rating and the different methods you can use to obtain the knowledge you must have to perform your job aboard ship. Remember, information is usually available when you need it. You just have to know where to look. This chapter will, we hope, serve as a guide to help you locate and use the information that you will require.
