🔍 Key Concepts

• Canister-type gas masks vs. self-contained breathing apparatus (SCBA) • How gas mask canisters are rated for specific hazards • Whether gas masks supply oxygen or only filter existing air

💭 Think About

• Think about what a canister on a gas mask actually does: does it create breathable air, or clean the air that’s already there? • Consider whether one canister can safely protect you from all types of gases, or if they must be matched to certain hazards. • Ask yourself if there are any limitations on how long a filter or canister remains effective once in use or once opened.

✅ Before You Answer

• Verify whether canister-type gas masks have an independent supply of oxygen or rely on ambient air. • Check if canister-type gas masks are approved only for specific contaminants/atmospheres or for all hazards. • Confirm whether canisters can have a stated service life or time limit for safe use printed or stamped on them.
