Which practice protects elastomer components during cleaning of the SCBA exterior?

• A. Avoid harsh solvents that degrade elastomers.
• B. Soak in solvent.
• C. Expose to direct flame.
• D. Polish with abrasive cleaner.

Answer: (A)

Elastomer parts like seals, gaskets, and o-rings are vulnerable to chemicals used in cleaning. Harsh solvents can break down this rubbery material, causing cracking, swelling, or loss of elasticity, which can compromise the SCBA’s airtight seals and overall safety. The best approach is to protect these components by using mild cleaners or manufacturer-approved products and avoiding strong solvents. This preserves the integrity of the elastomers so they stay flexible and leak-free. Soaking in solvent exposes elastomers to prolonged chemical attack, increasing damage risk. Exposing parts to direct flame can burn or deform them, and abrasive cleaners can wear away or scar the elastomer surfaces. Keeping to gentle, appropriate cleaners helps maintain reliable seals and equipment performance.
