70% to pass

On a MODU, when may a work vest be substituted for a required life preserver?

A For use during boat drills
B For use during fire drills
C To replace a damaged life preserver
D At no time
AI Explanation

The correct answer is D) At no time. On a MODU (Mobile Offshore Drilling Unit), a work vest cannot be substituted for a required life preserver at any time. Life preservers are essential safety equipment that must be worn by personnel at all times when working on the MODU, as they provide buoyancy and protection in the event of an emergency, such as a man-overboard situation. Work vests are not an acceptable replacement for life preservers, as they do not provide the same level of safety and are not approved for use in place of required life preservers on a MODU.
