NFPA 1 mandates fire extinguishers in nearly every kind of building except family homes, duplexes, and manufactured homes. 13.6. 1.2* Where Required. Fire extinguishers shall be provided where required by this Code as specified in Table 13.6.
What do the codes on a fire extinguisher mean?
Fire extinguishers are classified by fire type. The A, B, C rating system defines the kinds of burning materials each fire extinguisher is designed to fight. The number in front of the A, B, or C indicates the rating size of fire the unit can extinguish.
Where should a fire extinguisher be located?
Extinguishers should be placed where they are readily accessible in the event of a fire, which typically includes normal paths of travel.
What is the OSHA standard for fire extinguishers?
NFPA recommends one 2-A fire extinguisher for every 3,000 square feet. OSHA requires employees to have access to an extinguisher within 75 feet. Employees should have access to a fire extinguisher within either 30 or 50 feet, depending on the hazard in question and the rating of the extinguisher (see below).
How do you calculate the number of fire extinguishers?
The calculation can be simplified by applying the rule of thumb that one 13A extinguisher covers 200 square metres of floor area. To calculate how many 13A extinguishers are required, divide the floor area by 200, and round up.
Do fire extinguishers need to be hung?
Fire extinguishers need to be mounted to the wall so that they are secure, visible, and readily accessible. It is also important to mount them in such a way that they cannot be easily moved or damaged.
