Servicing Fire Extinguishers

Fire extinguishers are our first line of defense against small to medium fires, and maintaining them in peak working condition is vital. But buying the right fire extinguisher is just the first step. This article will delve into the various services needed for proper fire extinguisher upkeep, including recharging, refilling, repair, and hydrostatic testing. We’ll discuss the typical costs of these services, whether or not they’re DIY-friendly, and how to find qualified professionals who can help.

Fire Extinguisher Recharging

Recharging a fire extinguisher involves replacing the extinguishing agent that has been expelled1. This is typically necessary after the extinguisher has been used or when regular inspection reveals it to be undercharged.

  • Average Cost: $20 to $50 per recharge2.
  • DIY Possible?: No. Recharging requires specific knowledge and tools1.
  • Finding Professionals: Look for a licensed fire protection service provider in your area. Verify their certification through NFPA or your local fire department3.

Fire Extinguisher Refilling

Refilling is similar to recharging and is often performed together. Refilling involves restoring the pressure within the extinguisher if it has lost charge over time4.

  • Average Cost: $15 to $252.
  • DIY Possible?: No. Like recharging, refilling should only be performed by trained professionals4.
  • Finding Professionals: Refer to the advice given for recharging.

Fire Extinguisher Repair

Fire extinguisher repair may be required if your extinguisher is damaged, its hose is cracked, or the locking pin is missing. It’s important to have your extinguisher inspected regularly to identify any necessary repairs5.

  • Average Cost: $10 to $50, depending on the extent of the repair2.
  • DIY Possible?: No. Repairing fire extinguishers requires specialist knowledge and tools5.
  • Finding Professionals: Reach out to a certified fire equipment dealer. Make sure they have a proven track record in fire extinguisher repair3.

Hydrostatic Testing

Hydrostatic testing is a process where the fire extinguisher is checked for structural integrity. It is typically required every 5 to 12 years, depending on the type of extinguisher6.

  • Average Cost: $30 to $502.
  • DIY Possible?: No. Hydrostatic testing involves potentially hazardous procedures and should only be performed by certified professionals6.
  • Finding Professionals: Choose a fire equipment dealer with specific credentials in hydrostatic testing. They should be able to provide proof of their qualifications3.

While the costs may seem high, neglecting these essential services could lead to ineffective fire extinguishers when you need them most, or potential fines for non-compliance with fire safety regulations [7]. Always remember: it’s better to be safe than sorry when it comes to fire protection!
