Which statement best describes PPE considerations for A3 refrigerants?

• A. PPE should minimize risk of static electricity
• B. PPE is optional
• C. PPE should be worn only during summer
• D. PPE should be highly decorative

Answer: (A)

A3 refrigerants carry a high fire risk, so the main precaution is preventing ignition. PPE must address this by minimizing static electricity, since a static spark can ignite flammable vapors. That means using anti-static or dissipative clothing and footwear, grounding and bonding equipment, and selecting tools and PPE that don’t generate sparks. PPE isn’t optional, and it isn’t tied to seasons or anything decorative; proper, static-control PPE protects you when handling or being in environments with these highly flammable refrigerants. The focus on reducing static electricity is the best guiding principle for safety in this context.
