What personal protective equipment (PPE) is advisable when handling Class K extinguishers or residues?

• A. No PPE is necessary.
• B. Sunscreen and gloves.
• C. Respirator and steel-toed boots only.
• D. Safety goggles or face shield, chemical-resistant gloves, and protective clothing.

Answer: (D)

Handling Class K extinguishing residues involves exposure to caustic wet chemical agents, so protection must cover the eyes, skin, and clothing. Safety goggles or a face shield guard against splashes getting into the eyes, which can cause burns or irritation from the alkaline residue. Chemical-resistant gloves keep the hands safe from caustic contact, reducing skin irritation and burns. Protective clothing acts as a barrier to prevent chemicals from reaching the skin and everyday clothing, making cleanup and decontamination easier and safer. While some PPE combinations might seem to cover parts of the hazard, the combination of eye protection, chemical-resistant gloves, and protective clothing provides the essential, comprehensive protection needed for these residues. The other options either miss critical protection (eye safety or chemical barrier) or include items that aren’t relevant to this specific hazard.
