Which practice is NOT recommended for personnel working in smoke-proof stairwells?

• A. Do not require PPE for personnel working in smoke-proof stairwells
• B. Hoist tools and equipment instead of carrying
• C. Assign several companies to share workload
• D. Enforce a 1:1 work time/rehabilitation time rule

Answer: (A)

In smoke-proof stairwells, Protection for responders is non-negotiable. PPE, including respiratory protection, protective clothing, helmet, gloves, and eye protection, is essential because smoke, heat, and toxic gases can rapidly impair a firefighter’s ability to function. Limited visibility and the physical stress of maneuvering in confined spaces increase the risk of injury or incapacitation. Not requiring PPE would leave personnel vulnerable to inhalation of hazardous smoke, burns, and obscure vision, making it unsafe and not recommended.

The other practices support safer operations and rehab: hoisting tools and equipment prevents carrying heavy loads, which reduces fatigue and the chance of dropping gear or losing balance; spreading workload among several teams can help manage fatigue and maintain a steady, safe pace; and enforcing a 1:1 work-to-rehabilitation time rule ensures responders have adequate rest and monitoring between exertions, helping prevent overexertion and heat stress.
