I needed fire extinguishers for my business and Fire Science did a great job installing the necessary fire extinguishers that I needed to be compliant with my insurance company and the city. They set up my account so that they will call me every year for the yearly inspection. It’s so helpful to have one less thing to remember! Highly recommended!

Fire Extinguisher Sales & Service

Plan to check your fire extinguishers monthly. Then, hire a licensed professional to inspect your portable equipment once a year. The fire department doesn’t inspect fire extinguishers, so you need to find a fire extinguisher inspection company for the job. When you do, expect the technician to follow this fire extinguisher inspection checklist:

  • Ensure extinguishers are installed in the proper locations as required by law
  • Each cylinder should be unobstructed and easy to access in an emergency.
  • Check for any physical damage to the cylinder, such as leakage or corrosion.
  • Make sure the tamper seal is not broken and the nozzle is not clogged.
  • Ensure no components are wobbly, damaged, or missing.
  • Check the pressure gauge. Lift the extinguisher to ensure it feels full.
  • Ensure the operating instructions are legible and facing outward.
  • Initial and date the inspection tag to keep track of how often you’re inspecting your extinguishers.

If you’re looking for one of the highest-quality fire extinguisher companies “near me,” you’ve found it with Fire Science Techniques. We test all your fire extinguishers to ensure they are compliant so you are ready in an emergency.

A hydrostatic test involves placing the cylinder inside a test chamber and subjecting it to excessively high pressure. If the extinguisher holds up, it can be refilled and put back in service for another six years until the next round of internal maintenance. If the cylinder fails the test, it must be retired and replaced with a new one.

Fire Science Techniques offers fire extinguisher maintenance and testing at our South Holland, IL facility. With our services, you can feel confident that your extinguishers are safe and effective to use against a fire.

A partially depleted extinguisher is less effective at putting out fires than a fully charged one. If you discharge an extinguisher, whether by accident or while battling a blaze, call Fire Science Techniques to request a refill. We’ll loan you an extinguisher while we take care of your fire extinguisher refill to ensure your Naperville, IL building remains protected.

In addition to refilling your existing supply of fire extinguishers, we can also aid in the replacement process. Fire extinguishers don’t have a set expiration date—as long as they continue to pass visual inspections and hydrostatic tests, you can keep using them for decades.

Once your extinguishers wear out—or if any are subject to a recall—Fire Science Techniques can provide you with replacements. We offer a comprehensive range of extinguisher options, so you’re sure to find the type, size, and brand you’re looking for.


Fire extinguishers should typically be inspected according to regulatory standards, which often recommend annual inspections. However, certain environments or fire extinguisher types may require more frequent inspections.

A fire extinguisher inspection involves a visual check for damage, pressure testing to ensure proper function, and a functional test to confirm the extinguisher discharges correctly. The inspector also verifies the type and level of extinguishing agent and updates the inspection tag with the date and any required maintenance.

Fire Science offers comprehensive fire extinguisher training sessions to make sure your team is ready to act in the event of an emergency.
