How are water-type extinguishers operated?

• A. Hand pump or pressurization
• B. Pull pin and squeeze
• C. Twist valve and spray
• D. Push button release

Answer: (A)

Water extinguishers put out fires by delivering a steady stream of water to absorb heat and cool the fuel. They are designed to work in two ways: a hand-pump action, where you physically move a pump handle to force water out, and a stored-pressure system, where the water is already pressurized inside the cylinder and is released when you activate the lever or trigger. These two methods cover how water extinguishers are operated. The other described actions don’t match how water extinguishers are built to release water. This type is used for ordinary combustibles (Class A) and should not be used on electrical fires or fires involving oils.
