Until the initial attack hoseline is in position to attack the fire, the portable pressurized water extinguisher, aka "the can," can be used as an effective tool in reducing or controlling the spread of fire. A pressurized water extinguisher can help control a mattress fire or a smoldering fire in a wall or ceiling bay. The "can" allows a firefighter to get close to a door where fire is extending out and close it, confining the fire to that area of the structure. The can is also useful when protecting a member conducting a search for victims by allowing the firefighter to access areas past the fire or protecting the escape route back to safety.

Tip: The portable water fire extinguisher can be used in a multitude of situations and in different types of fires. It can be used on class “A” and some class “B” fires. If using on a class “B” fire, place a finger over the nozzle tip to produce a fine spray. The spray pattern is also useful on other types of fires as well; this pattern achieves a cooling effect with better application. Do NOT use on electrical fires.
