Which precaution is explicitly listed for water glycol extinguishers?

• A. Never use on electrical fires
• B. It should be stored near the exit
• C. It can be used on any electrical equipment
• D. It must be used with gloves

Answer: (A)

Water glycol extinguishers rely on water-based cooling and film formation to tackle ordinary combustibles. A key safety rule with this type is that it must never be used on electrical fires because water conducts electricity, creating a serious shock risk to the operator and potential damage to energized equipment. Even with glycol additives, the risk remains, so the instruction is to avoid electrical fires entirely and de-energize the system if possible, then use a non-conductive extinguisher.
