Vessel Radar and Communication Systems
- The servicing of vessel radar and communication systems must be done safely and in accord with 29 CFR 1915.89, Control of Hazardous Energy, which requires the systems to be incapable of energizing or emitting radiation before any employee begins work (29 CFR 1915.85(a) and (b)).
- When a vessel is supplied by electric shore power, the employer must take the following precautions before energizing any of the vessel’s circuits: the vessel must be grounded, each circuit to be energized must be equipped with over-current protection that does not exceed the rated current-carrying capacity of the conductors, and each circuit to be energized must be in a serviceable condition (29 CFR 1915.83(c)(1), (c)(2)) and (c)(3)). Overcurrent protection devices include circuit breakers and fuses.
- A responsible vessel's representative, a contractor, or other qualified person (i.e., with proper training, knowledge, or experience) must inspect each circuit to be energized, to determine that it is in a safe condition before the electric shore power source is energized (29 CFR 1915.83(c)(3)).
