SafetyCâu 693 / 700
On a jobsite, how should portable fire extinguishers for ordinary combustibles (Class A) be positioned so workers can reach one quickly?
a.So the maximum travel distance to an extinguisher is about 75 feet, with roughly one for each 3,000 square feet of floor area
b.Locked in the site office so they are not stolen
c.One per building only, no matter how large the floor area
d.Only near the fuel storage area, since that is the only fire risk

Correct: for Class A hazards, extinguishers are placed so the travel distance to reach one is no more than about 75 feet, commonly at least one for each 3,000 square feet of protected floor area. Locking them away defeats quick access. One per building regardless of size can exceed the travel-distance limit. Fire risk is not limited to fuel storage, so covering only that area is inadequate.
