What Size Fire Extinguisher Should you Purchase?
NFPA 10, 2013 Edition recommends the following:
E.3.5 The area that can be protected by one fire extinguisher with a given A rating is shown in Table E.3.5. These values are determined by multiplying the maximum floor area per unit of A, shown in Table 188.8.131.52, by the various A ratings until a value of 11,250 ft² (1045 m²) is exceeded.
Fire Extinguisher Location/Placement
The NFPA 10 - Standard for Portable Fire Extinguishers gives specific instruction on the proper location and placement.
Fire extinguishers shall be conspicuously located where they are readily accessible and immediately available in the event of fire.
Fire extinguishers shall be located along normal paths of travel, including exits from areas.
Fire extinguishers having a gross weight not exceeding 40 lbs. shall be installed so that the top of the fire extinguisher is not more than 5 ft. above the floor.
Fire extinguishers having a gross weight greater than 40 lbs. shall be installed so that the top of the fire extinguisher is not more than 3-1/2 ft. above the floor.
In no case shall the clearance between the bottom of the fire extinguisher and the floor be less than 4 inches.
How to Use Fire Extinguisher
