You likely see fire extinguishers in your daily life. But when was the last time you thought about them? Probably not since the last fire drill. It’s easy to overlook these safety devices until you need one, but when a fire breaks out, you need your fire extinguisher to work.
Understanding Fire Extinguisher Lifespans
The typical fire extinguisher lifespan is between 10 and 12 years. However, certain factors can shorten this timeframe. Like any other piece of equipment, fire extinguishers degrade over time or external conditions can affect them. Different types of fire extinguishers have different lifespans.
Disposable Fire Extinguishers
Disposable fire extinguishers have a set lifespan of around 12 years. These aren’t designed to be recharged, so you’ll need a new one once they’ve been used or are 12 years old. Regularly checking the pressure gauge can give you an idea of its functionality if you’re unsure about its age.
Rechargeable Fire Extinguishers
Rechargeable fire extinguishers are designed for a longer lifespan. You can usually expect them to last around 12 years, according to the National Fire Protection Association (NFPA). The key to keeping them working is regular maintenance and recharges.
Generally, you should have them inspected and recharged every six years. This ensures they’ll be ready in an emergency.
Portable Fire Extinguishers
Portable fire extinguishers also fall under the 10- to 12-year lifespan. They should undergo hydrostatic testing around the 10-year mark. This test examines the extinguisher’s outer shell to ensure it’s strong enough to hold pressure and won’t burst during use.
Factors Affecting Fire Extinguisher Lifespans
A fire extinguisher’s lifespan isn’t just about how many years have passed. Like any device, fire extinguishers can wear out or become unusable due to different circumstances. Several factors can significantly impact how long your fire extinguisher remains functional.
Temperature Extremes
Fire extinguishers are sturdy, but they aren’t invincible. Exposure to very hot or cold temperatures can weaken the components or even affect the chemicals inside. Storing an extinguisher below -40 degrees Fahrenheit or above 120 degrees Fahrenheit can lead to malfunctions or decreased performance.
Just as you wouldn’t leave food in scorching heat or freezing cold, you need to treat your fire extinguisher with care regarding temperature. Extreme temperatures can impact its inner workings and decrease its lifespan.
Damage and Wear
Physical damage is another reason for a shortened fire extinguisher lifespan. Replace it if you notice dents, bulges, a broken extinguisher handle, or visible signs of wear. Contact a professional to see if they can recharge it or if you need a full replacement.
Remember, you don’t want to discover your fire extinguisher is damaged when you need it. You need a dependable fire extinguisher that’s in good working order, just like you’d want a dependable car in an emergency.
Missing Inspection Tag
The small inspection tag on your fire extinguisher is important. It keeps a record of all inspections and maintenance. A missing inspection tag is a red flag, and it’s best to get a new one rather than rely on one with an unknown history.
This could indicate potential pressure loss or other problems that weren’t recorded. The inspection tag is like a medical record—it shows if it’s been receiving regular check-ups.
Identifying When To Replace Your Fire Extinguisher
Besides obvious signs like a broken pin, other indicators signal your fire extinguisher may need replacing. Here are a few more things to check during your monthly fire extinguisher checks.
- Pressure Gauge: Is the needle in the green zone, indicating adequate pressure? If it’s slowly decreased, your extinguisher may have a leak and you should replace it.
- Hose and Nozzle: Look for cracks, rips, or clogs. A compromised hose or nozzle can render your extinguisher useless, and you don’t want it failing during an emergency.
- Handle: Check for a broken or wobbly handle. Make sure you can grab the extinguisher handle and give it a shake. You need to be confident it can withstand the pressure when you squeeze it.
- Tamper Seal: The tamper seal ensures the fire extinguisher hasn’t been used. A broken seal means it has been discharged and needs to be recharged.
- Locking Pin: This prevents accidental discharges. A missing or damaged locking pin requires immediate replacement.
- Visual Inspection: Look for signs of corrosion rust on the cylinder. If you notice anything, replace it.
Understanding OSHA Regulations For Business Owners
Business owners have extra responsibilities. You’re dealing with your safety and the safety of your employees, which is where OSHA (Occupational Safety and Health Administration) regulations come in. OSHA sets specific standards for workplace fire safety, including fire extinguisher maintenance and inspection.
OSHA standard 1910.157 requires employers to provide, maintain, and test all portable fire extinguishers. This is important because not complying can result in fines and jeopardize the well-being of your staff. In the US, fire departments respond to over 350,000 home fires per year, making fire safety of the utmost importance.
Making The Right Choice: Recharging Vs Replacing
Rechargeable fire extinguishers can be refilled until their 12-year replacement mark, but how do you know when it’s more cost-effective than buying a new one? It depends. In some cases, especially smaller canisters, buying new might be cheaper than recharging, so compare prices before deciding. Ultimately, the choice often depends on your needs.
Maintaining Your Fire Extinguisher
Knowing when to replace fire extinguishers is good practice, but maintaining them is equally important. Fire extinguishers, like smoke detectors, need to be maintained properly to ensure they’re in good working order. There’s more to keeping one ready than simply replacing it.
You can do regular maintenance to ensure it’s always ready:
- Monthly Visual Inspections: Quickly look at your extinguisher once a month. Check for obvious damage to the canister, ensure the pressure gauge is green, and the pin is intact. If anything seems off, have it checked by a fire safety professional.
- Yearly Professional Inspections: Have a qualified technician inspect your extinguishers yearly. This professional inspection digs deeper to verify things you can’t check. They will install a new tamper seal with a date, showing it’s been inspected.
- Six-Year Recharges: Get rechargeable fire extinguishers refilled every six years. A qualified technician will replace the chemicals and ensure it’s pressurized correctly, making it good as new. Many certified fire equipment companies provide fire extinguisher recharge services, and some fire departments might too.
- Proper Storage: Where you keep your fire extinguisher can impact its effectiveness. Store it upright. Keeping it at an angle can affect its functionality when you need it. Also, avoid extremely hot or cold places, as these temperature fluctuations can negatively affect the lifespan and performance of your fire extinguisher.
