Look for a metal tag or decal showing the last test date. Examine the fire extinguisher's hose and discharge nozzle for damage. Also check to see that the handle locking pin, or wire is intact. If not, the extinguisher could have been used and now has to be refilled. If the extinguisher has any damage, especially surface damage such as dents, or has been discharged or tampered with, it must be inspected again by a qualified person.
Some facilities have automatic sprinkler protection.
If your alternate work area has this, check to see that the sprinkler heads have not been painted. Paint can clog the sprinkler head and prevent it from operating properly. Storage under and around sprinkler heads should be limited to no closer than 18 inches in any direction to allow ample clearance for the water spray. Do not permit anything to be attached to or suspended from a sprinkler head. Ideally, the sprinkler system should be tied into the building's fire alarm system so that when a sprinkler head is activated, the proper authorities are notified immediately.
