What PPE consideration is appropriate when using extinguishers in enclosed spaces?

• A. No PPE required
• B. Only eye protection
• C. Only hearing protection
• D. Respiratory protection if needed

Answer: (D)

Air in enclosed spaces can quickly become filled with smoke, fumes, and extinguisher powders, making inhalation hazards the primary concern. The best PPE approach is to perform a hazard assessment and use respiratory protection if there is any potential for inhalation exposure, with the type of respirator chosen based on the level of hazard and ventilation. Eye protection might be used to guard against splashes or particulates, but it doesn’t address inhalation risks as effectively as a respirator. Hearing protection isn’t typically necessary for extinguisher use in these conditions. Therefore, respiratory protection if needed is the appropriate PPE consideration.
