Fire extinguishers in Hong Kong: types, water and electrical fires

Common extinguishers in Hong Kong include water, foam, dry powder, carbon dioxide and clean-agent types. Electrical equipment, flammable liquids, cooking oils and ordinary combustible materials need a suitable agent. Check the label for the extinguisher's uses and restrictions.

Selection and use should follow the premises risk, approval requirements, cylinder label and manufacturer instructions. An untrained person should not attempt to use equipment when the fire type or extinguisher suitability is uncertain.

Conventional water extinguishers are intended for materials such as wood, textiles and paper. FSD warns against their use on electrical equipment, flammable liquids or metals. If suitable equipment is unavailable, put personal safety first and call 999.

FSD home-safety guidance identifies dry powder and CO2 for electrical equipment fires, but the model, label and actual risks still matter. Consider isolating the supply only if safe and without delaying escape; do not touch burning, smoking or damaged equipment.

The uses of a clean-agent extinguisher depend on its agent and product label. FSD's selection leaflet compares clean agents, CO2, water, dry powder and foam. Review the uses and restrictions with the contractor before buying.

Read the agent name, fire classifications, warnings and inspection date on the label; do not rely on cylinder or band colour alone. Ask an appropriately registered contractor about unclear labels, damaged markings or equipment due for inspection.

Only consider using an extinguisher on a very small fire at its earliest stage if you are trained, have suitable equipment, have a clear safe exit behind you and will not be exposed to smoke. If any of these conditions is missing, leave and call 999.

Stop immediately if the fire grows, smoke develops, one attempt does not control it or you feel unsafe. Never let the fire get between you and the exit, and do not go back for another extinguisher.

Confirm that the extinguisher is in its designated place, clearly marked and accessible. Look for rust, deformation, leaks or damage to the cylinder, hose, nozzle, handle and safety pin. Where a gauge is fitted, it should be within the manufacturer's specified range.

Do not open, discharge, refill or repair a cylinder yourself. Arrange a qualified person for annual inspection, pressure testing or disposal under the applicable requirements. For voluntarily installed domestic equipment, first confirm the rules and any exemption that applies.
