Prior to entering a compartment containing an atmosphere potentially dangerous to life or health, you should don an approved self‐contained breathing apparatus. Which one of the listed devices is a self‐contained breathing apparatus?

A fresh‐air breathing apparatus

A demand‐type breathing apparatus

A canister‐type gas mask

All of the above

Why should you wear a self‐contained breathing apparatus before entering the engine room after the fixed CO2 system has been discharged to combat a major fire?

Because carbon dioxide breaks down in a fire into carbon monoxide which may cause blood poisoning in the person breathing this gas.

Because carbon dioxide is a colorless and odorless gas that becomes highly toxic in the presence of high temperatures and will quickly incapacitate a person exposed to this gas.

Because carbon dioxide dilutes the oxygen concentration in the atmosphere and may cause asphyxiation.

This action is unnecessary as carbon dioxide is not poisonous nor toxic but is a relatively harmless gas.

What is a major advantage of the demand‐type self‐contained breathing apparatus?

The equipment is lightweight and the wearer can work without difficulty in confined spaces.

The regulator is designed to provide the user with quick adjustments to the air supply by a knob located near the high pressure hose connection.

The equipment is lightweight and the wearer can work without difficulty in confined spaces.

The speed with which it can be put into operation is around 45 seconds.
