When cleaning the mask of an SCBA, use a soap and water solution of no more than what degrees Fahrenheit?

• A. 90
• B. 110
• C. 120
• D. 140

Answer: (B)

Cleaning the SCBA mask with soap and water should be done at a temperature that protects the mask’s materials and its seal. The facepiece is made of elastomeric materials that can soften, warp, or degrade if exposed to heat. Keeping the cleaning water at or below 110°F provides effective cleaning while avoiding damage to seals, gaskets, and the overall fit. Temperatures higher than that—like 120°F or 140°F—increase the risk of material distortion or degradation, which could compromise the mask’s safety. A cooler temperature, such as 90°F, would be safe but does not reflect the maximum allowable limit, which is what the question asks for.
