Question 3606 Deck General

The correct answer is D) the same self-contained breathing apparatus required with the fireman's outfit. The regulation that makes this the correct answer is that a MODU (Mobile Offshore Drilling Unit) must have a self-contained breathing apparatus that is the same as the one required for the fireman's outfit. This is to ensure adequate protection for personnel in the event of a gas leak from a refrigeration unit on the MODU. The other options are incorrect because they do not meet the specific requirement for the same self-contained breathing apparatus as the fireman's outfit. An oxygen breathing apparatus, a gas mask, or a portable ventilation system would not provide the same level of protection required for this specific application on a MODU.
