NFPA 10 Table 5.2.1

[George McGerd]

Does anyone know what is meant by "maximum floor area per unit of 'A' " as listed under NFPA 10 Table 5.2.1. How does one determine the value of "A"? Thanks in advance for the education.

Look at annex E for help

6.2.1.2.1 The minimum number of fire extinguishers for Class A hazards for each floor of a building shall be determined by dividing the total floor area by the maximum area to be protected per extinguisher as determined by Table 6.2.1.1. (See Annex E.)

Ok it it is telling you maximum floor area per extingisher depending on the hazard classification

as in one 2A per 3000 sq ft

Thanks. We are using 4A's in a light hazard area. Would the maximum floor area then increase to 6000 sf? If so I am good. If not I am having problemo
