Which PPE maintenance action is most likely to reduce its effectiveness?

• A. Regular inspection for wear and damage
• B. Storing PPE away from heat
• C. Cleaning PPE with strong solvents daily
• D. Improper storage with oils and solvents on the gear

Answer: (D)

PPE works as a protective barrier because its material integrity and cleanliness are maintained. When oils or solvents are left on the gear during storage, they can migrate into the protective material and cause chemical degradation—softening, swelling, embrittlement, or cracking of elastomeric gloves, coatings, and seals. This weakens the barrier and can lead to failure in use, increasing exposure to hazards. The other habits support protection—inspecting for wear catches problems early, and storing away from heat preserves material properties. Cleaning with strong solvents is risky if the cleaners aren’t compatible, but the direct chemical attack from oils and solvents left on the gear is most likely to reduce effectiveness.
