Which statement is a precaution when using a water glycol extinguisher?

• A. It should be stored upright only.
• B. It must be refilled after use immediately.
• C. On initial discharge, force of extinguisher may scatter burning loose material.
• D. It is safe to use on electrical fires.

Answer: (C)

When using a water glycol extinguisher, the immediate discharge can physically disturb burning material. The force of the initial blast may scatter burning debris or embers to other areas, potentially spreading the fire before you’ve had a chance to control it. That’s why this statement is a key precaution: start by aiming at the base of the flames and use a steady, controlled stream to suppress the fire rather than a quick burst that might fling material around. Remember, water glycol extinguishers are for ordinary combustibles and are not safe for live electrical fires, since the liquid conducts electricity. After use, the extinguisher should be recharged by a qualified technician, not refilled immediately, and other handling details like storage are separate considerations.
