Gauges

There is a gauge on most extinguishers to measure the pressure of its contents. A fire gauges extinguisher can be “overcharged” meaning the contents are under too much pressure, “discharged” meaning that there is not enough pressure to work correctly or “in the green” which means that the unit is properly charged.

The standard round gauge was found on all but the personal watercraft units. Over time, or after it has been used, a fire extinguisher will loose pressure and will cease to work properly.

Most of our test extinguishers were not rechargeable. A rechargeable extinguisher can be taken to a service station for maintenance. If it is not rechargeable then it should be discarded when the gauge reads “discharged” or it has been in service for 12 years from manufacture.

Partial Discharge

Fire extinguishers are designed to rapidly release fire retardant onto their target. partial discharge when activated, the firing mechanism pierces a gas cylinder exerting additional pressure in the cylinder propelling the retardant out of the open nozzle. During our test we found that a partially discharged dry chemical extinguisher was inoperable after a few minutes. If you have a flare up after several minutes, a partially discharged unit might not work. It is important to replace or service the extinguisher as soon as possible.
