Another important aspect of fire extinguishers is placement. Fire extinguishers are intended for a rapid deployment while the fire is still small. If you have to find an extinguisher in the closet or go downstairs to get it, chances are the fire will be too big for it to be effective.
The fire extinguisher should be mounted on the wall in a visible location. Second, the extinguisher needs to be placed on an egress path out of the home or business. Always leave yourself the option to get outside if the extinguisher is not effective. (The recommended placement of fire extinguishers is in the kitchen, the garage, and one for every level of the home; businesses should consult with a registered design professional or fire protection professional for placement.)
