Fire Extinguisher Inspection & Service FAQ
How often do commercial fire extinguishers need to be inspected in New Hampshire?
Per NFPA 10 and New Hampshire state fire codes, commercial fire extinguishers require three levels of inspection: a monthly visual check (can be done by the owner), a comprehensive annual professional inspection, and periodic internal maintenance (usually every 6 or 12 years depending on the type). LHR Fire Protection provides the certified annual tagging and documentation required for business compliance.
What is included in a professional fire extinguisher annual inspection?
Our certified technicians perform a multi-point check, including verifying the pressure gauge is in the “green,” checking the pull-pin and tamper seal, inspecting the hose for blockages or cracks, and ensuring the physical canister is free of corrosion. We then provide the required dated inspection tag that fire marshals look for during their walkthroughs.
Do you provide fire extinguisher sales and installation in Manchester and the Seacoast?
Yes! We don’t just inspect; we help you determine the correct type and quantity of extinguishers needed for your specific layout. Whether you need an ABC Dry Chemical for an office in Manchester or a Class K for a commercial kitchen in Raymond, we supply, mount, and tag your equipment to ensure full coverage.
When should a fire extinguisher be replaced instead of recharged?
Most modern extinguishers can be recharged after use, but they should be replaced if the cylinder shows signs of rust, if the handle is wobbly, or if the nozzle is cracked. If you have an older “disposable” plastic-head unit, these cannot be serviced and must be replaced after 12 years or any use. Our team can evaluate your current inventory and recommend the most cost-effective solution.

Our Clients Say
Posted on Google Jordan ShallowTrustindex verifies that the original source of the review is Google. Joe expedited my fire extinguisher inspection. I just googled them and they came down the next morning BEFORE my inspection. Thanks to the team. I highly recommend all of them and will use them in the future.Posted on Google RonTrustindex verifies that the original source of the review is Google. LHR Fire has been instrumental in getting our condominium complex's fire sprinkler system up to code. Our association is over 20 years old, and we discovered that the original installation had not been done correctly by a previous fire company, leading to leaks and ruptures over time. LHR worked with us to develop a plan for installing expansion tanks on the antifreeze lines and replacing the original check valves and sprinkler heads. They have diagnosed several longstanding issues. What impressed us most is their communication. They take the time to explain what they're seeing, discuss options, and work collaboratively to troubleshoot problems rather than simply replace parts. Overall, LHR is proactive rather than reactive. They take pride in doing the job right the first time, their technicians are knowledgeable and professional, and their pricing has been fair. I highly recommend them to anyone looking for a reliable fire protection contractor.Posted on Google Steven whiteTrustindex verifies that the original source of the review is Google.

We’ve worked with LHR Fire Protection at one of our business locations for several years, and they’ve consistently ensured that our fire protection systems remain up to code, fully compliant, and operating safely. Their attention to detail has given us tremendous peace of mind, knowing we can always rely on them to help keep our staff and customers safe. When we expanded to another location, Joe Keller conducted a thorough walkthrough, identified areas that needed to be brought up to current safety standards, and quickly implemented the necessary improvements. His knowledge, professionalism, and commitment to doing the job right made the entire process smooth and stress-free. We truly appreciate the professionalism, quality workmanship, and dedication to safety that Joe Keller and the entire LHR Fire Protection team demonstrate. I highly recommend them to any business looking for a dependable fire protection company. Thank you, Joe Keller, and thank you to the entire LHR Fire Protection team!
