Types of Fire Extinguishers
Class A extinguishers put out fires in ordinary combustible materials such as cloth, wood, rubber, paper, and many plastics.
Class B extinguishers are used on fires involving flammable liquids, such as grease, gasoline, oil, and oil-based paints.
Class C extinguishers are suitable for use on fires involving appliances, tools, or other equipment that is electrically energized or plugged in.
Class D extinguishers are designed for use on flammable metals and are often specific for the type of metal in question. These are typically found only in factories working with these metals.
Class K fire extinguishers are intended for use on fires that involve vegetable oils, animal oils, or fats in cooking appliances. These extinguishers are generally found in commercial kitchens, such as those found in restaurants, cafeterias, and caterers. Class K extinguishers are now finding their way into the residential market for use in kitchens.
Tips for hiring a qualified Fire Equipment Service Company for Restaurant Fire Systems
Rockaway New Jersey
Restaurants must have their systems inspected every six months, Forman said. When seeking a fire equipment service company qualified to perform these important inspections, make sure they will perform the following tasks during the inspection:
- Trip the system from the pull station.
- Trip the fire system from the terminal link.
- Visually inspect the cable for the fusible links, brackets, CO2 cartridges, mechanical head and other parts of the fire system.
- Conduct a visual inspection of plenum and ducts to determine the amount of grease buildup that exists.
- Check to ensure there is proper coverage of the nozzles over the equipment.
- Inspect to make sure the nozzles have proper caps.
- Make sure the gas automatic shut-off valve works adequately.
- Make sure the pull pin and the seal are replaced properly and the system is tagged.
Tagging the system shows fire safety officials when the last inspection was performed and also indicates that the inspection was done properly and successfully, unless the inspection company has noted otherwise on the tag or the fire report, Forman said.
It also is important for restaurant owners to have their fire extinguishers inspected routinely to ensure that they are in optimum working condition if needed.
Restaurants also need to have Class K extinguishers. These extinguishers are rated for handling fires that result from cooking oils and fats. These extinguishers are easy to determine from others because they come in a 6 liter stainless steel container reather than red one like most dru chemical extinguihsers, Forman said.

Fires have four elements in order to exist. They must have oxygen, heat, a chemical reaction and fuel. In order to successfully extinguish a fire, one of these elements must be taken away, that is, extinguished.
There are five different classes of fires. These fires are lettered A, B, C, D and K. Each of these fires has a different fuel. Class A fires comprise of ordinary combustibles, occurring in wood, paper, plastic, trash or cloth. Class B fires are comprised of flammable liquids and gases, which include gasoline, paint, petroleum oil, propane, and butane (cooking oil and grease are not included in class B). Class C is comprised of fires that involve electrical equipment such as home appliances (often kitchen related), motors, and transformers. Combustible metals cause class D fires; that is, materials such as potassium, magnesium, sodium and aluminum. Finally, class K fires occur due to cooking oils and grease, including animal and vegetables fats.
Next, there are six main kinds of fire extinguishers. Having a basic understanding of each kind of extinguisher will help you determine what kind you may need to purchase for the safety of your family and home.
The first type of extinguisher uses water or foam. These extinguishers take away the heat, and the foam extinguishers also separate the oxygen. Water extinguishers can only be used on class A fires; if they are used on other types they can actually do more harm than good. Foam extinguishers can be used on classes A and B only.
The next type of extinguisher is a carbon dioxide extinguisher. It takes away the heat, as well as dispersing the oxygen. It is recommended they be used on class B and C fires; they often prove to be unsuccessful on class A fires.
The third type of fire extinguisher is one that utilizes dry chemicals. They work by disrupting the chemical reaction of the fire. This kind of extinguisher is popular because it has proven to be effective on classes A, B, and C fires. Be sure to use a multipurpose dry chemical extinguisher…a simple dry chemical extinguisher will not work on class A fires.
Wet chemical fire extinguishers are effective on class K and sometimes class A fires as well. They were originally invented to aid in commercial kitchen or deep fat fryers, which often found in fast food joints or restaurants.
Clean agent fire extinguishers have halon agents as well as agents that are good for the environment. These extinguishers are often used on class B and C fires, though large clean agent extinguishers can be effective on class A fires as well.
Finally, dry powder extinguishers are often used only on class D fires or combustible metal fires. These extinguishers remove the heat in addition to separating fuel from the oxygen.
