Question 186Safety & Environmental - QMED

The correct answer is A) canister-type gas mask. This is the correct answer because the illustration SF-0012 depicts a canister-type gas mask, which is a type of respiratory protective equipment used to filter out harmful gases, vapors, or particulates from the air. Canister-type gas masks are approved for use by the US Coast Guard and are a required piece of safety equipment for certain operations and environments. The other answer choices are incorrect because they describe different types of breathing apparatus that are not shown in the illustration. Fresh-air hose masks, demand-type breathing apparatus, and cylinder-type air masks have different design and functionality compared to the canister-type gas mask depicted in the illustration.
