How To Use a Fire Extinguisher
All extinguishers must be readily accessible, preferably not stowed next to
common fire sources. It is recommended that they be attached to the boat.
Before using portable extinguishers, read the instructions.
Never use a foam extinguisher on electrical fires, because these extinguish-
ers contain water and you might be electrocuted.
Never try an extinguisher to see if it works properly—the valves may not
reseal and the extinguishing material may gradually leak.
After using an extinguisher, recharge it before using it again. Check your
fire extinguisher at least once every six months for the pressure level and
signs of powder on the nozzle. If the extinguisher contains a dry chemical
extinguishing material, turn the extinguisher end-to-end. If the chemical is
packed, shake it or hit the bottom with your hand to loosen it.
