Clean Agent Extinguishers ›

NFPA 2001 has defined the term “clean agent” as an electrically nonconductive, volatile or gaseous fire extinguishing agent that does not leave a residue upon evaporation. Since the banning of Halon in 1994, after it was found to deplete the ozone, the three most common clean agents used in fire suppression systems are: 3MTM NovecTM 1230 Fire Protection Fluid1, ChemoursTM FM-200TM Fire Suppressant2 and inert gases. Clean agent fire extinguishers are effective on Class B and Class C fires (used typically for petrol, oil, propane, butane, etc.) and work by releasing gas into the air, reducing the oxygen that feeds the flames without damaging equipment by leaving a residue.

Common Applications:

  • Telecommunication facilities
  • Server rooms
  • Offices with computers or electronics
  • Data centers
  • Art storage centers
  • Museums
  • Clean rooms

Foam Extinguishers ›

Foam fire extinguishers are used for Class A and Class B fires, and, in particular, offer a fast and effective means of suppressing flammable liquids. Foam consists of a stable mass of small air bubbles that form a foam blanket when expelled. This foam blanket works to extinguish the fire by cooling, separating the flame from the product surface, suppressing vapors and smothering. It also contains the flame to prevent reignition. Foam is the primary suppression agent used anywhere flammable liquids are transported, processed, stored or used as an energy source. It is preferred over fire sprinklers for hotter fires dues to its ability to quickly cool a fire, which minimizes property damage caused by the fire.

Common Applications:

  • Manufacturing plants
  • Hardware stores
  • Offices that store cleansers or paint
  • Flammable liquid storage areas

CO2 Extinguishers ›

CO2 extinguishers are primarily used for electrical fires and are the predominant extinguisher used in computer server rooms (Class C). They also put out Class B (flammable liquids, such as paint and petroleum) and all other Class C fires (energized electrical equipment, motors, transformers and appliances). Because they do not work by cooling the fire, they are ineffective on fires involving flammable solids.

Common Applications:

  • Mechanical rooms
  • Kitchens
  • Flammable liquid storage areas
  • Laboratories

Wheeled Unit Extinguishers ›

Wheeled unit fire extinguishers are larger than hand-held extinguishers. They are portable and easily moved to the point of the fire and manageable enough to be operated by one person. These extinguishers are available in a variety of sizes with available capacities ranging from 30 to 300 pounds and provide higher flow rates, which extend range and discharge time. A variety of extinguishing agents are also available for these units, such as carbon dioxide, dry chemical, dry powder and AFFF-type foam pre-mix solutions.

Common Applications:

  • Airports
  • Loading docks
  • Steel/Iron mills
  • Offshore platforms

Class K Extinguishers ›

In order to determine the correct extinguisher to put out a fire, it is critical to know how the fire started and why it is burning. Class K fires are a subset of Class B flames. Class B includes flammable liquid; however, Class K flames are specific to cooking fat and oils. These types of fires can spread quickly, so it is critical to have a Class K fire extinguisher on hand. These extinguishers use suppression agents that separate the fuel from the oxygen and help to absorb heat. The only effective extinguisher rated as Class K is a wet chemical fire extinguisher.

Because oils and fats are used to transmit heat and are often brought to high temperatures quickly, they have the potential to catch fire on the stovetop, in the oven, on the grill or even in the microwave. Be especially vigilant when using products such as olive oil, butter, margarine, bacon grease or lard.

Common Applications:

  • Commercial kitchen fires
  • Flammable liquid storage areas

Water Extinguishers ›

Water fire extinguishers are used for Class A fire risks including wood, paper and fabrics. These extinguishers work in two ways; they remove heat from the fire, and they deprive the fire of oxygen. Water extinguishers should not be used for Class B or Class C fires. If a water extinguisher is used on a Class B fire (flammable liquid, gas or paint) the discharge could help spread the flammable liquid or gas. If used on a Class C fire (electrical equipment), it could create a shock hazard.

Common Applications:

  • Offices
  • Break Rooms
  • Document storage areas

Class D Extinguishers ›

Class D fires are defined by the presence of burning metals. The most common metals involved in these fires are magnesium and titanium, while other metals include sodium, potassium, uranium, lithium, plutonium and calcium. These types of fires most often occur in laboratories, warehouses, factories and anywhere the manufacturing process cuts or drills metals. Class D fire extinguishers use a dry powder agent, which will not react with the burning metals and will smother the fire and reduce its spread.

Common Applications:

  • Laboratories
  • Warehouses
  • Manufacturing facilities
  • Other sites that use burning metals

High Flow Extinguishers ›

NFPA 10 requires high flow extinguishers for pressurized, flammable liquid and gas hazards such as at construction sites, fuel stations and propane filling locations as well as areas with three-dimensional class B hazards. These types of fires require higher flow rates than a standard extinguisher provides. The higher flow rate not only projects more agent onto the fire resulting in a quicker knock down, it also provides the operator more protection by placing a heavier stream of suppression agent between the operator and the fire.

Common Applications:

  • Propane filling stations
  • Gas stations
  • Auto repair facilities
  • Painting areas
  • Marine terminals

Cartridge-Operated Extinguishers ›

Cartridge-operated extinguishers are rechargeable, high-quality, durable extinguishers ideal for use in harsh environments. Unlike a traditional stored pressure extinguisher, which has the agent and pressure mixed in the same container inside the extinguisher, a cartridge-operated extinguisher has the powder/agent inside and a separate pressure cartridge outside the extinguisher that must be activated to pressurize the extinguisher. These units are used primarily in construction and heavy equipment environments and protect areas that house chemical storage, marinas, spray paint booths and welding.

Common Applications:

  • Heavy construction sites
  • Oil pumping stations
  • Mining equipment

ABC Extinguishers ›

ABC fire extinguishers are ideal for many types of fire. These extinguishers use monoammonium phosphate, a dry chemical. Monoammonium phosphate chemically insulates Class A fires by melting at approximately 350°F and coating surfaces to which it is applied. It smothers and breaks the chain reaction of Class B fires and will not conduct electricity back to the operator in Class C fires. Because of its versatility, the ABC extinguisher is often the optimal choice to meet most needs for small fire suppression.

Common Applications:

  • Offices
  • Break Rooms
  • Laboratories
  • Chemical storage areas
