Which of the devices listed would be safe to use in a compartment with insufficient oxygen?
AI Explanation
The correct answer is B) Self-contained breathing apparatus.
A self-contained breathing apparatus (SCBA) is the only safe option listed for use in a compartment with insufficient oxygen. SCBA units provide a completely independent air supply, allowing the user to breathe safely in low-oxygen environments. The other options, such as a wet handkerchief, dust/gas mask, or canister-type mask, do not provide a self-contained air source and would not be adequate for use in a low-oxygen compartment, as they can only filter the surrounding air, which may be depleted of oxygen.
