Question 3600 Deck General

The correct answer is A) self-contained breathing apparatus. A self-contained breathing apparatus (SCBA) is a critical piece of equipment for a fireman's outfit, as it provides the fireman with a reliable source of air in a fire or other hazardous environment where the air quality may be compromised. This is required by Coast Guard regulations to ensure the safety of the fireman when responding to emergencies on board a vessel. The other options are not part of a standard fireman's outfit. A chemical protection face shield is used for handling hazardous chemicals, an approved work vest is for general safety, and a marlinspike is a tool used for splicing and working with ropes, but not part of a fireman's personal protective equipment.
