What cautions are to be taken when servicing a liquid cooling system?

• A. Wear proper PPE; coolant can be harmful if ingested and irritates skin; coolant can harm tires and rubber; clean spills immediately.
• B. PPE is not necessary; coolant is harmless; spills can wait.
• C. Only touch coolant with bare hands.
• D. Use water only; no PPE.

Answer: (A)

Handling a liquid cooling system safely starts with treating the coolant as a chemical that can irritate skin and eyes and may be toxic if ingested. That's why wearing proper PPE is essential: chemical-resistant gloves, splash goggles or a face shield, and protective clothing to prevent any contact with skin. Spills matter too—coolant on the floor or work surfaces can create slip hazards and can attack rubber components, hoses, seals, and even tires if it gets on them. Cleaning spills promptly helps protect people, equipment, and the environment, and it supports proper disposal of waste coolant. Options that say PPE isn’t necessary, that coolant is harmless, or that you can use only water with no PPE are not safe practices. They ignore the chemical hazards and the potential damage from spills, which is why the correct approach emphasizes protection and immediate cleanup.
