Danger of damaging the unit (Fire Extinguisher)

  • Exposure to temperatures outside the safe range (by the manufacturer) may damage a fire extinguisher.

  • For example:
    • if we enter in cab on a tractor or backhoe that has been parked all day in the hot Tennessee sun, we learn the metal inside is so hot it burns our skin on contact and plastic items such as a favorite sunglasses’ case has melted or at least warp due to the heat.
    • If we try to enter that vehicle a few months later it will be so cold our glove will instantly freeze to the cab door (which, incidentally, will freeze and shut).
  • The fire extinguisher, mount in that cab is exposed to these extreme temperatures.
  • We also factor into this scenario, that in such a rough and tumble environment the extinguisher may also bump, jar, and knock about. In such a situation it is very important that we check the unit regularly, especially the pressure indication gauge, making sure the needle is in the green.

  • A store pressure dry chemical extinguisher becomes a bomb when it is into a fire.
  • It is a time delay bomb perhaps, since manufacture of the unit is to easily withstand an internal pressure of 390 psi to 720 psi, depending on the model. This of course makes the explosion all the more violent when the heat finally raises the pressure inside the canister beyond it’s breaking point.
  • Even an “empty” extinguisher is a seal container. Heat will force the residual gases present inside the canister to expand, pressing outward from inside the canister until it`s weak point ruptures.
  • This may be explosive or the bottle may act as a projectile. This is one reason we never recommend tossing an extinguisher, not even a empty unit, into a fire.
