Red Line Cartridge Operated Fire Extinguisher

ANSUL Redline Fire Extinguishers – The Latest and Greatest in High Hazard Technology

Move over portable water-mist fire extinguishers, the newest line of fire extinguishers have arrived. ANSUL Redline, cartridge-operated portable fire extinguishers have hit the market. They bring with them the latest and greatest in high hazard technology. Water-mist fire extinguishers were the newest technology recently available in the fire equipment dealer world. However, they are not comparable to the ANSUL Redlines, simply because they are not designed to extinguish the same classes of fires.

Water-mist extinguishers are specialty extinguishers designed to put our Class A or Class C fires using a fine, deionized water mist. The new ANSUL model is designed for high hazard occupancies, or in layperson’s speak – dangerous situations that are likely to have hotter, more damaging fires. A superior fire extinguisher if you work in the high hazard fields of aviation, chemical, mining, oil and gas, petro-chemical, or power-generation. ANSUL Redline fire extinguishers are built tougher for these situations. Instead of steel or aluminum shells, they use carbon steel. They are also designed to hold up better in the field. ANSUL uses a special polyester powder paint to ensure that the extinguishers will resist cracking and corrosion. To be fair, we can’t compare apples to oranges. So instead of comparing this line of fire extinguishers to another brand, let’s see how they compare to the ANSUL Sentry.

Redline vs. Sentry

How do ANSUL Redline extinguishers compare to the multipurpose ABC extinguishers? Let’s see:

If you operate a light occupancy hazard business, you will not need an ANSUL Redline fire extinguisher. They have been designed to meet special needs in the fire protection industry. If you do operate a high hazard occupancy business, you are in luck. You’ve probably noticed that your extinguisher has some wear and tear. This new design incorporates a special powder coating to keep it in top shape. This extends the life of your fire extinguisher. Per the National Fire Protection Association (NFPA, portable fire extinguishers must be condemned when on or more of the follow occur:

-repairs by soldering, welding, brazing, or use of the patching compounds

-where corrosion has caused pitting under a removable nameplate or name band assembly

-where the depth of a dent exceeds 1/10 of the greatest dimension of the dent, if not in a weld, or exceeds 1/4 inch if the dent includes a weld

-where any local or general corrosion, cuts, gouges, or dings have removed more than 10 percent of the minimum cylinder wall thickness

This means that if your extinguisher is damaged, you cannot repair it. It also means you can’t cover the corrosion with a stick, and if it is dented or cut you may need to dispose of it. All of these things could happen under normal circumstances. The chances of them happening in a high hazard area are increased. It was a smart move by ANSUL to create a different coating system.

Red Line Cartridge Fire ExtinguisherBut Wait, There’s More

If the bells and whistles weren’t enough, additional protection can be purchased through upgrades. These are not standard and need to be specifically ordered or mentioned when purchasing. They allow the consumer to further customize the extinguisher to their fire safety needs.


This line of portable fire extinguishers includes a corrosion-resistant model. The exterior of this model receives the standard coating treatment, plus a thick zinc-based coating on the shell. The other metal pieces of the extinguisher are black anodizes for additional protection. The cartridge is painted using epoxy to resist damage. While designed for high hazard, these might be a plus for business owners on the beach. The salty area of Tampa Bay beaches corrodes regular fire extinguishers quite quickly.

High-Flow Nozzle

These are differentiated by a red handle. They push the extinguishing chemical out more quickly than regular flow extinguishers. These would work well for three-dimensional fires, pressure fires, and obstacle hazard fires. They would also work on Class B and C fires – flammable/combustible liquid fires and electrical fires.

Low Temperature

Many people don’t know that most fire extinguishers are rated for use from 40 to 140 degrees Fahrenheit. In cooler areas, certain fire extinguishers can use an anti-freeze solution to further protect from lower temperatures. These newer ANSUL models are rated for use at temperatures as low as -65 degrees Fahrenheit. Although – if a commercial cooler or refrigerator space were large enough to merit an extinguisher, these would be a great choice.
