Fire Extinguishers

Fire Extinguisher Inspection & Service

Bartec can take care of all your fire extinguisher needs, helping you make sure to choose the best and correct type of extinguisher for your building.

In the image to the left, we see how the letters on the label of a fire extinguisher indicate what type of fire to use it on. It is critical to make sure to use the right extinguisher on a particular type of fire.

NOTE: Although ABC and BC Dry Chemical extinguishers can control a fire involving electronic equipment, the National Fire Code (NFPA 75-1999 edition), Section 6-3-2, specifically advises against dry-chemical extinguishers for fires involving computers or other delicate electronic equipment due to the potential damage from residues.

Multi-Purpose Dry Chemical (ABC)

Multi-purpose fire extinguishers utilize a dry chemical agent (siliconized mono ammonium phosphate) that suppresses Class A, B and C fires.

They are definitely the most versatile as they can be used to extinguish common combustible, flammable liquid and live electrical equipment fires. ABC extinguishers are great for home, office, flammable liquid storage, boiler room, chemical facility and warehouse applications. Fire extinguishing capacity is rated in accordance with ANSI/UL 711: Rating and Fire Testing of Fire Extinguishers. The ratings are described using numbers preceding the class letter, such as 1-A:10-B:C. The number preceding the A multiplied by 1.25 gives the equivalent extinguishing capability in gallons of water. The number preceding the B indicates the size of fire in square feet that an ordinary user should be able to extinguish. There is no additional rating for class C, as it only indicates that the extinguishing agent will not conduct electricity, and an extinguisher will never have a rating of just C.

Purple K Dry Chemical

Purple K fire extinguishers contain a specially fluidized and siliconized potassium bicarbonate dry chemical, which is particularly effective on high-hazard Class B and Class C fires. They are the preferred fire-fighting agent of the oil, gas, chemical and utilities industries.

K-Class Extinguisher

Wet Chemical extinguishers are the best restaurant kitchen appliance hand portable fire extinguishers you can purchase. They contain a special potassium acetate based, low PH agent developed for use in pre-engineered restaurant kitchen systems. The recent trend to more efficient cooking appliances and use of unsaturated cooking oils, dictates the use of a hand portable fire extinguisher with greater fire fighting capacity and cooling effect to combat these very hot and difficult fires. The superior fire fighting capability of the wet chemical agent is placed exactly where you aim it with no chemical residue to clean up. They are deemed to be the best portable fire protection available to supplement pre-engineered restaurant fire suppression systems.

Carbon Dioxide (CO2)

CO2 is discharged as a white clous that smothers the fire by eliminating its oxygen. It is a clean, non-contaminating, odorless gas and is safe for use on clothing, equipment, valuable documents or food. CO2 extinguishers are particularly useful for computer rooms, flammable liquid storage areas and hospital operating room fires. They are highly effective, easy to use, and leave no messy residue behind.


Halotron is a “Clean Agent” HydroChloroFluoroCarbon discharged as a rapidly evaporating liquid which leaves no residue. It effectively extinguishes Class A and B fires by cooling and smothering and it will not conduct electricity back to the operator. Halotron is pressurized with Argon gas and is an EPA and FAA approved HCFC blend B agent approved for use on Class A, B and C fires. It has a low Atmospheric Lifetime (3 to 11 years). Halotron is intended for use in areas formely protected by Halon 1211 hand portable extinguishers such as computer rooms, telecommunications facilities, clean rooms, data storage areas, offices (for protection of sensitive electronic equipment), boats and vehicles.

Water Mist

Water mist extinguishers are designed to provide customers with an environmentally friendly clean agent. The extinguishant is simply distilled water and therefore is non-toxic and leaves no residue. It is effective on Class A common combustible fires and Class C live electrical equipment manufacturing plants, clean rooms and hyper baric chambers. Is the ultimate extinguisher for Class A fires, especially where a potential Class C (electrical) hazard exists. The fine spray from the unique misting nozzle provides safety from electrical shock, greatly enhances the cooling and soaking characteristics of the agent and reduces scattering of the burning materials. Unequivocally the best extinguisher for hospital environments, telecommunications facilities and “clean room” manufacturing facilities.

D Class Dry Powder

Class D fire extinguishers contain a sodium chloride based dry chemical extinguishing agent. Heat from the fire coats the metal, excluding air and dissipating the heat from the burning metal, such as magnesium, sodium, potassium, sodium potassium alloys, uranium and powdered aluminum. They are specifically for use in areas where combustible metals are present.

Important facts to know regarding a fire

No one is required to put out a fire, however, if you attempt to extinguish one you need to know about fire extinguishers.

  1. Only attempt to put a fire out if you have a clear exit from the room.
  2. Do not turn your back on a fire and keep your exit from the room open and accessible at all times.
  3. Extinguishers will work for approximately 30 seconds.
  4. If you have not put the fire out in that time, leave the area immediately.
  5. Once you leave a burning room, do not re-enter.
  6. Close the door to a room with a fire.
  7. Leave the door unlocked as the fire department will need to enter.
  8. If you know the type of fire and contents of the room, please advise the Chief Fire Warden for the building or the Fire Department personnel.
