Fire Extinguisher Services
Complete Fire Extinguisher Services in Los Angeles & SoCal
Sales, Installation, and State Fire Marshal Certified Maintenance to Keep Your Business Compliant.
Support fire safety compliance and help protect your facility. Fully licensed by the California State Fire Marshal (SFM License #E2390) and CSLB (#976500).
Fire extinguishers are your first line of defense, but they are only effective if they work when you need them most. At SOS Fire Services, we don't just sell equipment; we provide a complete safety partnership. We specialize in the inspection, maintenance, repair, and installation of all fire extinguisher types. Our certified technicians ensure your facility meets all NFPA 10 standards, Title 19 regulations, and local Fire Department codes, serving clients from correction facilities to commercial kitchens across Los Angeles, Orange, and Ventura counties.
In California, maintaining these units is not merely a best practice; it is an enforceable legal requirement under California Code of Regulations (CCR) Title 19 and local municipal fire codes. An expired tag, depressurized cylinder, or improperly mounted unit may lead to a citation, required corrective action, or insurance and compliance questions, depending on the circumstances and the authority having jurisdiction.
Our Core Services
We provide a full spectrum of fire extinguisher solutions:
Annual Inspection & Tagging
Comprehensive on-site certification ensuring your facility is fully compliant with Title 19 regulations. We inspect, weigh, and tag each unit, verifying it's ready for immediate use
Under CCR Title 19 (§ 575.1) and NFPA 10, every commercial fire extinguisher must undergo an annual physical maintenance check by a State Fire Marshal licensed technician. Our technicians check the extinguisher's condition, pressure indication where fitted, hose and nozzle, pin and seal, weight where applicable, and other manufacturer- and code-required items. Passing units receive the official California State Fire Marshal inspection tag punched with the month, year, and technician license number.
→ Learn more about our full certified protocol on our Annual Fire Extinguisher Inspection page.
Recharge & 6-Year Maintenance
From standard refills after use to the mandatory 6-year internal teardown. We service units on-site to ensure pressure levels meet manufacturer specs and safety codes.
Did an employee discharge an extinguisher, even for a few seconds? Under California Title 19 CCR § 575.1(a), fire extinguishers must undergo professional maintenance and recharge immediately after any use before being returned to service. Our mobile workshops carry bulk multi-purpose ABC dry chemical, Purple-K, Carbon Dioxide (CO2), and Class K wet chemical agents with high-pressure nitrogen charging manifolds to refill and recertify your units on the spot.
→ Explore emergency and post-discharge service on our Fire Extinguisher Recharge & Refill page.
Stored-pressure dry chemical and dry powder extinguishers subject to a 12-year hydrostatic test require 6-year internal maintenance under CCR Title 19 § 575.4. Technicians discharge and empty the unit, examine internal components and cylinder condition, replace parts as needed under the manufacturer's instructions, then recharge and document the service.
The California Verification of Service Collar:
Under Title 19 CCR § 596(c)(1), technicians must install an official, non-removable Verification of Service Collar around the neck of the cylinder during any internal teardown or recharge. This tamper-evident ring provides visible evidence of service when required. (Note: Cartridge-operated and Carbon Dioxide units are legally exempt from this collar requirement).
Hydrostatic Testing
High-pressure structural integrity testing required every 5 or 12 years, depending on extinguisher type. We verify cylinder safety according to strict DOT specifications to ensure your equipment can handle the pressure.
Fire extinguishers operate under tremendous internal pressure. Over time, metal fatigue, moisture, and temperature fluctuations can weaken the cylinder. Under CCR Title 19 § 592 (Table 5) and NFPA 10:
5-Year Examples: Wet chemical (Class K) and carbon dioxide (CO2) extinguishers generally require hydrostatic testing every 5 years. Other types, including some water, foam, and dry chemical constructions, may also fall on a 5-year cycle.
12-Year Examples: Many stored-pressure ABC dry chemical extinguishers with mild-steel, brazed-brass, or aluminum shells require testing every 12 years. Confirm the exact interval by agent, cylinder construction, markings, and applicable rules.
The test method, marking, and follow-up service depend on the cylinder and applicable DOT and California requirements. Refer to the dedicated hydrostatic testing page for the full type-by-type schedule.
→ Review full testing specifications on our Hydrostatic Testing Services page.
Fire Hose & Cabinet Services
Complete inspection, un-racking, and re-racking of fire hoses. We also install and repair cabinets, ensuring nozzles and valves are functional and code-compliant.
Extinguishers must remain accessible and shielded from workplace damage or accidental knocking:
Recessed, Semi-Recessed & Surface Cabinets: Heavy-gauge steel and aluminum cabinets designed for lobbies, corridors, and parking structures.
Vehicle-Rated Brackets: Heavy-duty running-board and cab mounting brackets for commercial delivery vans, flatbeds, and warehouse forklifts.
High-Visibility Signage: 3D projection signs and photoluminescent wall plaques to ensure rapid locating during zero-visibility smoke conditions.
→ View cabinet and hardware options on our Fire Cabinets & Hoses page.
Why Professional Inspection is Non-Negotiable
California law and national fire codes are strict. An unserviced extinguisher isn't just a code violation; it's a liability. As a fully licensed company (CSLB #976500 & State Fire Marshal #E2390), we take the guesswork out of compliance.
What Our Annual Inspection Includes:
Visual Check: Ensuring safety seals are intact and nozzles are clog-free.
Pressure Verification: Confirming the gauge is in the "green" zone.
Weight Analysis: Weighing the unit to determine fullness and potential leakage.
Physical Exam: Checking the cylinder for rust, dents, or external damage.
Tagging: Applying the official State Fire Marshal certification tag upon passing.

Industry-Specific Fire Protection Solutions
Tailored Extinguisher Solutions for Your Facility Type
Restaurants & Commercial Kitchens
Commercial fryers and woks generate extreme-temperature grease fires that conventional dry chemical units cannot safely extinguish. We install and service potassium-acetate-based Class K Wet Chemical Extinguishers, engineered to saponify hot cooking oils without thermal splashback. Need whole-kitchen defense? Pair with our complete Commercial Kitchen Fire Suppression Systems.
Warehouses & Logistics Hubs
Extinguisher size, rating, quantity, and distribution in high-piled storage centers are calculated based on commodity hazard classification, warehouse layout, and strict Class A/B travel distance thresholds. We supply high-flow 10 lb and 20 lb ABC dry chemical units, wheeled units, and heavy-duty bollard/column mountings.
Data Centers, Telecom & Electrical Rooms
ABC dry chemical discharge can leave residue that is difficult to clean from sensitive electronics and may damage equipment. We supply and service residue-free Clean Agent Extinguishers (Halotron I & CO2) designed for sensitive IT infrastructure. For room-wide flood systems, visit our Special Hazard & Clean Agent Systems page.
Commercial Delivery Fleets & Industrial Vehicles
Select vehicle-rated extinguishers and secure brackets appropriate to the vehicle and applicable CHP, DOT, and FMCSA requirements.
Fire Code Violation Remediation
Received a Fire Inspection Notice of Violation? Fast Remediation.
If a municipal fire inspector issued a Notice of Violation for expired tags, missing units, improper mounting heights, or obstructed access, prompt correction helps address the notice and may reduce the risk of reinspection fees or other enforcement steps, depending on the AHJ.
SOS Fire Services provides expedited violation remediation across Los Angeles and Orange County. Our mobile teams can assess the cited extinguisher issues, install appropriate brackets, replace defective units, complete required service and tagging, and provide service documentation for the business and AHJ when applicable.

Frequently Asked Questions
Common questions about our services and compliance.
Can you inspect fire extinguishers before a fire marshal inspection?
Yes. SOS Fire Services can inspect your fire extinguishers before a scheduled fire department or fire marshal inspection. We can identify expired tags, damaged or discharged units, maintenance requirements and other extinguisher-related deficiencies so they can be addressed before the official inspection.
I just opened a business. How many fire extinguishers do I need?
The number, type and placement of fire extinguishers depend on your building layout, occupancy and fire hazards. SOS Fire Services can evaluate your commercial location and recommend the appropriate extinguisher coverage based on applicable fire code and safety requirements.
Can you replace expired or damaged fire extinguishers during the same visit?
Yes. If an extinguisher cannot be safely serviced or has reached a condition requiring replacement, SOS Fire Services can provide commercial fire extinguisher replacement options. Our technicians can also help ensure the correct extinguisher type, size and placement for your facility.
Can you service all of the fire extinguishers at my business in one visit?
Yes. SOS Fire Services can inspect and service multiple fire extinguishers during one scheduled visit. Our mobile service trucks are equipped to perform annual inspections, certification, recharging and many required maintenance services on-site, making this convenient for restaurants, offices, warehouses and other commercial facilities.
Can I get same-day fire extinguisher service in Los Angeles?
SOS Fire Services offers same-day fire extinguisher service in many Los Angeles County areas, subject to technician availability. Our mobile service trucks can perform inspections, annual tagging, recharging and many maintenance services directly at your business. For urgent service, contact our office to check current availability.
My fire extinguisher tag is expired. What should I do?
If your fire extinguisher certification tag has expired, schedule a professional inspection as soon as possible. SOS Fire Services can come to your business, inspect the extinguisher, perform any required maintenance or recharge, and provide a new certification tag when the extinguisher passes service requirements.
Who can certify and tag fire extinguishers for my business near me?
SOS Fire Services provides mobile fire extinguisher inspection, certification and tagging for businesses throughout Southern California. Our licensed technicians come directly to your location to inspect and service your extinguishers and provide the required certification tags. We serve businesses throughout Los Angeles County, Orange County, Ventura County, the San Fernando Valley, San Bernardino County and surrounding areas.
What are the NFPA standards for fire extinguisher maintenance in Los Angeles?
NFPA 10 and Title 19 require monthly visual inspections and annual professional maintenance for all fire extinguishers. Additionally, 6-year internal maintenance applies to stored-pressure dry chemical and dry powder units that require a 12-year hydrostatic test, and hydrostatic testing is due every 5 or 12 years depending on extinguisher type.
Where to buy fire extinguishers online in the US?
While many online retailers sell extinguishers, SOS Fire Services specializes in direct sales and professional installation in Southern California to ensure you buy the correct type and size for your specific hazards and code requirements.
Where can I get fire extinguisher installation in Los Angeles?
SOS Fire Services provides professional fire extinguisher installation throughout Los Angeles. We ensure all extinguishers are properly mounted, tagged, and compliant with local fire codes and Title 19 regulations.
Can you perform 6-year internal maintenance on-site?
For most standard dry chemical extinguishers, yes. Our mobile workshop trucks are equipped with closed recovery systems to perform 6-year maintenance and internal breakdown verification at your facility, so you are never left without protection.
Can you refill my fire extinguisher, or do I need to buy a new one?
In most cases, we can refill and recharge your existing commercial-grade extinguisher, which is often cheaper than buying a new high-quality unit. We refill Dry Chemical, CO2, and Class K units.
How often must extinguishers be inspected?
Monthly: A quick visual check (you can do this yourself). Annually: A certified inspection by a licensed technician (required by law). Every 6 Years: Internal maintenance/teardown for stored-pressure dry chemical and dry powder units that require a 12-year hydrostatic test. Every 5 or 12 Years (by type): Hydrostatic testing (pressure test).
How often do fire extinguishers need to be serviced in California?
In California, state regulations (Title 19 of the California Code of Regulations) require that all non-residential fire extinguishers must be professionally serviced;
- Annually (Once per year) by a certified technician
- Immediately After Use: If the extinguisher is discharged, even partially, it must be serviced and recharged.
- Monthly: A quick visual inspection is also required monthly and can be performed by the building owner or a designated employee
I used my extinguisher for 2 seconds. Do I really need to recharge it?
YES. Even a short burst breaks the seal and lowers the pressure. The powder can settle in the valve and cause a leak. Never put a used extinguisher back on the wall—call us for a recharge immediately.
Which extinguisher do I need for my business?
Fire extinguishers are classified by the type of fire they fight: Class A: Trash, wood, paper. Class B: Liquids (gasoline, oil). Class C: Electrical equipment. Class K: Kitchen grease/oil (Crucial for restaurants). Most offices need an 'ABC' extinguisher that covers standard hazards.
What should I consider when buying a new fire extinguisher cabinet?
You should consider the size and type of your extinguisher, whether you need a surface-mount or recessed cabinet, and if you require a padlock for fire extinguisher protection
What type of fire extinguisher do I need for my business?
It depends on your hazard type. Standard offices typically need ABC Dry Chemical extinguishers. Commercial kitchens require Class K extinguishers for grease fires. We can assess your site and recommend the correct coverage.
Do you sell fire extinguisher cabinets?
Yes. We sell most brands and sizes. Please contact our office for rates and brands available
Do you sell new fire extinguishers and replacement parts for extinguishers?
Yes. We stock a comprehensive inventory of all fire extinguishers brands and original replacement parts, including hoses, nozzles, gauges, pull pins, and seals for various extinguisher types
How often must commercial fire extinguishers be inspected in California?
Conduct and document a visual inspection at least monthly. Annual maintenance must be performed by qualified service personnel. Six-year internal maintenance and hydrostatic testing apply only to the extinguisher types and intervals specified by the applicable rules.
What happens if an extinguisher is discharged, even briefly?
Remove it from service and arrange the required maintenance and recharge before returning it to its location. Do not assume a partially discharged unit is ready for reuse.
Which extinguishers need six-year internal maintenance?
Stored-pressure dry chemical and dry powder extinguishers subject to a 12-year hydrostatic test require six-year internal maintenance under California Title 19 § 575.4. The technician should confirm the unit type and manufacturer instructions.
Is hydrostatic testing due every five or twelve years?
It depends on agent type and cylinder construction. Wet chemical/Class K and CO2 are common five-year examples; many stored-pressure ABC dry chemical units with mild-steel, brazed-brass, or aluminum shells are twelve-year examples. Other constructions may follow a five-year interval.
Where can monthly inspection records be kept?
California Title 19 § 574.5 permits the date and inspector initials on an extinguisher tag or label, a checklist kept on file, or an electronic system that provides a permanent record.
What should I do if a tag is expired or an inspector issues a notice?
Arrange an assessment promptly. A service provider can identify overdue maintenance or defective units, complete applicable corrections, and provide documentation for the business and authority having jurisdiction.

Excellent service. My restaurant had a grease fire on Labor Day weekend and the fire suppression system needed emergency repairs and recharging. Zohar and Juan were able to come out on Sunday and get the system back up and running. Very professional and friendly. Also, Zohar patiently answered all my questions and explained the process of his work. Would 100 percent recommend them and we will be using them for ongoing maintenance.

I own a restaurant in Buena Park, and on Saturday morning, my Ansul system would not turn the gas on or off. I called several companies looking for guidance/help and SOS was the only one courteous enough to help me troubleshoot the problem. Maureen not only was sympathetic to my plight, which de-escalated the stressful situation, she also walked me through the steps to get my gas up and running for business. My original fire company just blew me off, so now I look forward to using SOS for all my fire suppression needs. Taking the time to help shows the integrity of their service. Bravo!
