What temperature is used to rinse the facepiece after cleaning?

• A. 90°F
• B. 110°F
• C. 120°F
• D. 130°F

Answer: (B)

Rinsing the facepiece at a warm temperature around 110°F provides the right balance between effective cleaning and protecting the materials. Warm water helps loosen and wash away soap, oils, and residues more thoroughly than cool water, without risking damage to elastomeric seals, gaskets, or straps that can occur with hotter water. Water that's too cool (like 90°F) may leave residues and be less effective at rinsing. Water that’s too hot (120°F or 130°F) can degrade flexible components and coatings and could be unsafe for the wearer to handle. So, 110°F is used because it cleanly rinses without compromising the facepiece’s integrity.
