Which substance should be avoided when cleaning SCBA components due to potential material degradation?

• A. Water
• B. Manufacturer-approved cleaners
• C. Mild soap
• D. Solvents that can degrade materials

Answer: (D)

SCBA components use materials like elastomer seals, O-rings, plastics, and coatings that can be damaged by certain cleaners. Solvents that can degrade these materials may cause swelling, softening, cracking, or loss of elasticity, compromising seals and the integrity of the unit. Water, manufacturer-approved cleaners, and mild soap are safe options when used as directed because they are non-aggressive to these parts. If cleaning is needed beyond mild soap and water, always follow the manufacturer’s recommendations and avoid solvent-based cleaners unless they are explicitly approved.
