During overhaul, what level of personal protective equipment should firefighters wear?

• A. Full PPE with SCBA
• B. Coveralls and gloves
• C. Turnout gear without SCBA
• D. Regular uniform clothing

Answer: (A)

During overhaul, the environment can still hold heat, hidden embers, and toxic or oxygen-deficient atmospheres. The safest and most effective approach is wearing full PPE with an SCBA. The full protective ensemble shields the skin from heat and sharp debris, while the SCBA provides a reliable supply of breathable air, protecting the lungs from smoke, gases, and fine particulates that may linger even after visible flames are out. Lightweight or partial protection—such as coveralls and gloves alone, turnout gear without an air supply, or regular uniform clothing—does not address the critical inhalation hazard or provide full thermal protection, leaving firefighters at risk during overhaul.
