INSPECTION

Where an inspection reveals that tampering has occurred

or that the extinguisher is damaged, impaired, leaking

or has obvious corrosion, complete maintenance as

described on pages 9 through 16 should be followed.

To provide reasonable assurance extinguisher is charged

and operable:

1. Make certain the extinguisher is in its designated place,

is clearly visible and is accessible for immediate use.

Any obstructions that obscure it, or that would otherwise

impair its being readily accessible, should be removed.

2. Check the visual seal on the cartridge receiver and,

if provided, the tamper-proof seal on the fill cap. The

absence of a seal or a broken seal may indicate either

unreported use or tampering. In either case, a complete

maintenance check is required.

3. Ansul indicator fill cap models, in addition to a visual seal,

feature a red stem indicator which pops up in the center

of the fill cap and remains up after the pressure has been

relieved. Check the red indicator stem. If up, a complete

maintenance check is in order.

4. Remove the extinguisher from its mounting bracket and

heft (lift up and down slightly) to determine if it is filled.

5. Examine the extinguisher shell, cartridge guard, cartridge

receiver and all other external parts for evidence of physi-

cal damage, corrosion or other impairments.

6. Check the nameplate for readability – especially the oper-

ating instructions. If they are not legible, an instructed (but

not necessarily trained) person may not understand the

method of operation in the excitement created by a fire.
