Mounting Fire Extinguishers from H3R Performance

What to Look for when Buying a Fire Extinguisher with the H3R Performance Lineup

Too often, one of the most overlooked items when kitting out your expedition rig is a good quality fire extinguisher. With various hazards, either vehicle-based or around camp, a fire extinguisher is a must-have safety item.

Nothing will ruin a trip more than watching your rig burn to the ground, or worse be the beginnings of a wildfire. Just last year, in 2017, 88% of wildfires were caused by humans. A quality fire extinguisher is an investment into the safety of your life, your truck, or those in need that you might find on the trail.

When shopping for a fire extinguisher to add to my vehicle, I chose two 2.5 lb. units from H3R Performance, a MaxOut™, and a HalGuard™. A high-quality product with metal used for key components, backed by wonderful customer service, based right here in Northern California.

How to Read Fire Extinguisher Ratings

H3R Performance Fire Extinguisher

Let’s break it down, what all these symbols mean, the purpose of each, and why.

  • Class A: Ordinary Combustibles: Wood, paper, cloth, trash, and other ordinary materials. Water extinguishers or APW (air-pressurized water) are only suitable for class A fires.
  • Class B: Flammable Liquids & Gases: Gasoline, oils, paint, lacquer and tar.
  • Class C: Fires Involving Live Electrical Equipment. Such as appliances, wiring, circuit breakers, and outlets.
  • Class D: Combustible Metals or Combustible Metal Alloys. Typically found in chemical laboratories.
  • Class K: Fires in Cooking Appliances That involve cooking media: Animal or vegetable oils and fats

Ratings are described using numbers preceding the class letter.

Let’s use a 2.5 lb. MaxOut for example. It has an approved UL rating of 1A:10B:C.

The “A” rating is a water equivalency rating. 1A is equivalent to 1 1/4 gallons of water for Class A fires.

The number predicating Class B rating indicates the size of the fire in square feet that an ordinary user should be able to extinguish. So a 10B equates to 10 square feet of coverage.

There is no predicating numerical rating for class C, as it only indicates that the extinguishing agent will not conduct electricity.

What to Look for When Purchasing a Fire Extinguisher

What to Look for When Purchasing a Fire Extinguisher

#1 – UL Rating

Double check that your fire extinguisher contains a UL rating. The Underwriters Laboratories (UL) is a renowned third-party testing facility for public safety. A UL rating ensures that an extinguisher design has been subjected to standardized, uniform tests and has met minimum performance requirements covering such things as discharge time and discharge range. It is illegal to sell a non-UL listed fire extinguisher (e.g. this product) in many states.

Some non-UL listed products purport to be superior due to longer discharge times than the typical 9-12 second discharge time of a typical UL listed fire extinguisher. However, a longer duration is not indicative of the size of a fire it can extinguish.

#2 – Extinguishing Agent Used: Dry Chemical vs. Clean Agent

MaxOut™ (Dry Chemical):

  • Very good effectiveness (2.5 lb. achieves a 1A:10B:C rating)
  • Does not cause thermal shock or static shock when discharged
  • Potential damage to surface finishes and electrical components
  • Requires immediate cleanup

HalGuard™ (Halotron 1 Clean Agent):

  • Good effectiveness (2.5 lb. achieves 2B:C rating)
  • Does not cause thermal shock or static shock when discharged
  • Does not leave a corrosive residue
  • Maintains good user visibility during discharge
  • Attacks fire in hard-to-reach areas

#3 – Size of the Unit

  • 1 lb. – Ideal for small fires, convenient to mount in small areas
  • 2.5 lb. – Ideal size for car fires
  • 5 lb. – Ideal choice for RV’s, garages, trailers, or pits

#4 – Metal vs. Plastic

Fire extinguishers with plastic components tend to degrade over time, and could fail. Having an extinguisher with you is better than not, it isn’t worth the risk if that low-quality extinguisher were to fail, which can happen (CPSC Kidde Recall).

Having a quality made extinguisher with metal for key components (i.e. handle, nozzle, valve, siphon tube, bracket), although more expensive, could be the difference between your rig burning to the ground or not.

In addition, these extinguishers are typically refillable and can be reused.

#5 – Mounting Point

An unmounted extinguisher is a recipe for disaster.

During a rollover or crash, and unmounted extinguisher can become a projectile within your vehicle.

Choose a location where it can be easily accessible, without the potential for being covered by your gear.

TIP: Load vs Duration

The ability of an extinguisher to put out a fire is closely related to the load that it can expel. For example, a 10 lb. with a 9 second discharge time can put out a larger fire than a 1 lb. extinguisher with a 9 second discharge time.

This is due to more agent being expelled during the same discharge time. Something very important to keep in mind is what different brands quote.

For example; “Brand X” claims to have a long duration to suppress a fire. Imagine blowing out the candles on your birthday cake, which will be more effective? One large blow? Or slowly blowing the same amount of air?

Mounting Fire Extinguisher Under Seat

Mounting Fire Extinguisher Under 4Runner (5th Gen) Seat

Mounted under my driver’s seat is an H3R Performance 2.5 lb. HalGuard™ with their black Universal Seat Mount. If a fire were to appear under the dash, inside the main cabin, or within an engine bay.

It would have it readily available on my driver’s seat. One of the main benefits of having HalGuard™ is that it is a clean agent extinguisher.

It would not leave a corrosive residue on any finishes or do damage to my electrical system.

To make sure all my bases are covered, in the rear of my vehicle is a MaxOut™ 2.5 lb. unit. MaxOut™ is a dry chemical type, very good at extinguishing Class B and C fires as well as Class A.

The intended use for this rear extinguisher would be for small fires outside of my vehicle, or at my campsite. A backup unit to the 2.5 lb. HalGuard™ in the vehicle.

Extinguishing a Car Fire

  1. Stop the vehicle. Put it in park.
  2. Get passengers out of the vehicle. Have a passenger or bystander call 9-1-1
  3. Locate, remove extinguisher. Pull pin, and aim towards the base of the fire, squeeze handles together and sweep from side to side. Move closer but not too close as to scatter the burning material or liquid.
  4. If a fire is in the engine bay, pop the latch, but do not open fully. Aim the nozzle into the engine under the hood before opening fully. Opening the hood has the potential to make it worse.
  5. When the fire is out, back away and watch for possible re-ignition

Just got my H3R 2.5 Maxout and Extreme Duty Quick Release bracket NB300 to mount horizontally on Rago Fab MSP panel. Just like your top photo.Same issue as Peter Shaw below. Holes don’t match. Any tips on clean bolt up solution would be appreciated.

Thanks for the info. I’ll probably attach to a flat plate and then to the Rago panel. Or just get the billet mount.Thanks again.

I wish the Trail30 discount code still worked. They make great stuff but $420 for a 2.5 Halguard, Seat Bracket and Quick Release flat mount is pretty steep. Maybe they will offer a Black Friday discount this year?

Just wondering what you used to mount the extinguisher on the molle panel? I have a 5 pound ABC extinguisher that I want to mount. Got H3R’s NB425 quick release bracket, but the mounting holes don’t match up with the holes on my panels…

Just for info, some of the results from my recent layman fire extinguisher research:
Most people “in the know” recommend skipping the “A” rating, and getting just a “BC” rated extinguisher for vehicle use (Fuel and Oil fire, and Electrically safe).
Top racers on and off road appear to carry handheld Halon 1211 extinguishers.
Halon is considerably more effective than Halotron/HalGuard (a Halon substitute). If you check the ratings on a 2.5 lb extinguisher, the Halotron/HalGuard is rated at 2B:C, while the Halon in the same size is rated at 5B:C. That equates to 2 square feet of fire extinguishing compared to 5 square feet of fire extinguishing with Halon.
Halon gas manufacturing has been discontinued, but there are considerable reserves of Halon available.
New Halon extinguishers are all over the market for purchase, but they are not cheap. A 2.5 lb Halon 1211 extinguisher runs $200 to $280 depending on where you look.
Recent checking with an extinguisher company quoted me approximately $75 to refill a 2.5 lb Halon 1211 extinguisher. Halon itself is about $25 per pound I believe.
For me, the extra cost of the Halon is well worth paying to have the extra fire fighting capability when it comes to my personal safety or possibly saving my $50,000 4Runner from burning to the ground.

Thanks for your info. One thing I would like to add is that with the fire extinguisher mounted in front of the seat, there is less leg room. That may not seem to be a big deal, but in the event of a frontal collision, if the foot area is caved in, there is less room to avoid leg and foot damage. Example, a woman had a habit of putting her purse in the same place your extinguisher is and had a left frontal collision causing significant crushing into the foot area. With her purse occupying foot space, she had her feet and heels crushed with multiple fractures which it is still not known if she will need amputations or not. She is still in a wheel chair and unable to do much with her legs and feet more than one year after the accident. She was not in a 4Runner, but the principle is the same. Prepare ahead of time what to do with your feet during a collision. Less space in any crush zone equals higher risk for injury.

Excellent write-up! I’m definitely going to get that under the seat mount.
