Question 1745 Deck General

70% to pass

The light on a personal flotation device on an OSV must be replaced _______________.

A every six months
B when the power source is replaced
C when it is no longer serviceable
D each year after installation
AI Explanation

The correct answer is C) when it is no longer serviceable. According to the US Coast Guard regulations, the light on a personal flotation device (PFD) on an Offshore Supply Vessel (OSV) must be replaced when it is no longer serviceable, regardless of the time since installation or the power source replacement. The regulations do not require the light to be replaced on a specific schedule, such as every six months or annually. As long as the light remains in good working condition, it can continue to be used. The other options (A and D) are incorrect as they specify fixed replacement intervals, which are not the requirement for PFD lights on OSVs.
