GENERAL
This work package describes the repair and replacement of an engine room light as an example of incandescent lighting fixture
repair. Repair of the incandescent lights in the pilothouse and accommodation module is similar.
WARNING
Replace or repair components only after the affected circuit has been secured, locked
out, and tagged out. Performing replacement with the circuit energized may result in
damaged equipment and serious injury or death to personnel.
Certain lighting circuits may have more than one source of power. This is especially true
of those lighting fixtures that contain both red and white lights. Always ensure that all
power sources are secured, locked out, and tagged out prior to replacing the lighting
fixtures. Failure to comply can result in serious injury or death.
