Question 3745 Deck General

70% to pass

Due to the hazards involved with Halon extinguishers on a MODU, the size II extinguisher may only be used _______________.

A outside
B in an emergency
C on class B fires
D on class C fires
AI Explanation

The correct answer is A) outside. The reason for this is that Halon extinguishers, while effective on Class B and C fires, pose a significant risk to personnel when used in enclosed spaces due to the hazardous nature of the Halon gas. As such, Coast Guard regulations stipulate that Halon extinguishers of Size II or smaller can only be used outside, and not in the confined spaces of a MODU (Mobile Offshore Drilling Unit). The other answer choices are incorrect because B) using Halon extinguishers in an emergency inside would be unsafe, C) they are not limited to Class B fires, and D) they should not be used on Class C (energized electrical) fires inside a MODU.
