70% to pass

On a MODU, CO2 extinguishers must be weighed _______________.

A monthly
B quarterly
C semiannually
D annually
AI Explanation

The correct answer is D) annually. The reason is that according to the regulations set by the U.S. Coast Guard, CO2 extinguishers on a MODU (Mobile Offshore Drilling Unit) must be weighed annually to ensure they are properly charged and ready for use in an emergency. This requirement is specified in the Coast Guard regulations for fire protection equipment on offshore units. The other options are incorrect because monthly, quarterly, and semiannual inspections are not the regulatory requirement for CO2 extinguishers on a MODU. The Coast Guard mandates annual weight checks to maintain the operational readiness of this critical firefighting equipment.
