Fire Extinguisher Maintenance Info
When should I bring my Extinguisher in for Service?
Every 12 months, from the last time your extinguisher tag had been hole punched.
Do I need to make an Appointment?
In most cases, feel free to come in during our business hours! If you have more than 10 extinguishers, please give us a call to let us know you are coming so we can be better prepared for your arrival.
Do you have a Mobile Service?
Yes! Give us a call at 414-475-0959, or email sales@genfire.net and we will get you all of the information needed to get set up. We normally are able to get out to new customers within 2 weeks.
What is an Annual Inspection?
During an annual inspection we provide a:
- Visual inspection of cylinder, checking for rust/ dents that may render the
extinguisher inoperable.
- Check hose for obstructions, and pressure gauge for function
- Agitate internal chemical to reduce clumping
- New yearly inspection tag and record log
- New tamper seal, and pull pin is checked
- Validate extinguisher serial number to check for any recalls
- Replace/fix external parts, such as hose, strap, pull pin or handle if
needed
And will cost $8.50 no matter the size or type of extinguisher.
What does it mean if my Extinguisher needs an "Internal"?
Every 6 years to comply with NFPA standards your extinguisher will need to be internally inspected for every 6 years based on the cylinders manufacturing date.
6 Year Internal
- Full tear down of extinguisher
- Removal and disposal of old ABC Dry Chemical Check cylinder shell, and internal parts
(valve, spring, hose, downstem, o-rings) for damage or rust.
- Lubricate and replace internal o-ring's around the neck and valve
- Recharge with new ABC chemical, and nitrogen to operating pressure New verification
collar, and sticker indicating service
- Dipped in water to check for any Nitrogen leaks
12 Year Hydrostatic Test
-Everything included in the annual and 6 year test +
-Pressure Test Cylinder to 3X its operating pressure
How do I know if my extinguisher is obsolete?
1. The "1984 Rule" (NFPA 10)
The most critical factor is the manufacture date. NFPA 10 (Standard for Portable Fire Extinguishers)
mandates that dry chemical stored-pressure extinguishers manufactured prior to October 1984 must be
removed from service at their next 6-year maintenance interval or hydrostatic test.
2. Obsolete Shell Construction
- Copper or brass shells (unless they are pump tanks).
- Joined by soft solder or rivets.
- Inverting types (units that must be turned upside down to
operate).
- Plastic head units
3. The "Parts & Listing" Liability
To perform a compliant 6-year internal maintenance, we must replace the valve stem, O-rings, and other internal seals with parts that are UL listed for that specific manufacturer.
