Fire Extinguisher Refilling

When and why do fire extinguishers need to be recharged?

• Immediately after use, no matter how little is discharged: Even if you discharge an extinguisher accidentally for a mere second or two, this decreases the internal pressure enough that you should have it recharged. Topping off the cylinder ensures you have its full extinguishing power if you ever need to use it.
• Periodically throughout its life: Tiny leaks can eventually reduce the pressure, making it necessary to recharge the extinguisher. We recommend recharging every 2 years.
• Any time the pressure gauge is low: Environmental factors or damage to the cylinder may cause depressurization. An inspection ensures the extinguisher is still structurally sound, and recharging puts it back in service.
