For the best selection of wet and dry extinguishers in Campbell River, get in touch with the experts at The Fire Shop. With so many fire extinguishers to choose from on the market today, selecting the proper one for your home can be a daunting task. Everyone should have at least one fire extinguisher at home, but it's just as important to ensure you have the proper type of fire extinguisher to match your needs. Fire protection experts recommend different types of extinguishers for use in the kitchen, the garage and workshop.
4 Categories of Protection
Fire extinguishers are divided into 4 categories, based on how effective they are on different kinds of fires. Each fire extinguisher also has a numerical rating that serves as a guide for the amount of fire the extinguisher can be expected to control. The higher the number, the more fire-fighting power is available. The following is a quick guide that will help you to choose the right type of extinguisher:
Some fires may involve a combination of these classifications.
Your fire extinguishers should have ABC ratings on them.
Most Common Types of Fire Extinguishers
Water extinguishers, or APW extinguishers (air-pressurized water), are suitable for class A fires only. Never use a water extinguisher on grease fires, electrical fires or class D fires - the flames will spread and make the fire bigger! Water extinguishers are filled with water and pressurized with oxygen.
Dry chemical extinguishers come in a variety of types and are suitable for a combination of class A, B and C fires. These are filled with foam or powder and pressurized with nitrogen.
BC – This is the regular type of dry chemical extinguisher. It is filled with sodium bicarbonate or potassium bicarbonate. The BC extinguisher leaves a mildly corrosive residue which must be cleaned immediately in order to prevent any damage to materials.
ABC – This is a multipurpose dry chemical extinguisher. The ABC type is filled with monoammonium phosphate, a yellow powder that leaves a sticky residue that may be damaging to electrical appliances, such as a computer.
CO² (carbon dioxide) extinguishers are for class B and C fires. They don't work very well on class A fires because the material usually reignites. CO² extinguishers have an advantage over dry chemical in that they leave behind no harmful residue. That makes carbon dioxide a good choice for an electrical fire involving a computer or other delicate instrument.
NFPA 10 Services
The Fire Shop will perform all the services required by NFPA 10 – Standard for Portable Fire Extinguishers.
Annual Inspection – This refers to a complete inspection of the extinguisher and must be performed by a professional. A visual inspection is done to insure the extinguisher is operable. This includes checking the nozzle for debris or clogging, checking the gauge and tamper seal, and turning the unit upside down to loosen powder. We also check dates to see if certain other maintenance procedures need to be done. A date check will reveal the need for hydro-testing, which must be performed on dry chemical extinguishers every 12 years.
Six Year Maintenance – Every six years, extinguishers requiring a 12-year hydro-test shall be emptied and subjected to a thorough examination of mechanical parts, as well as extinguishing agent and expelling means. When applicable maintenance procedures are done during periodic recharging or hydro-testing, the 6-year requirement will begin from that date.
Recharge – All types of fire extinguishers must be professionally recharged immediately after any use. This should be done by a local service company who has the trained personnel, extinguishing agents and equipment to do it properly. The extinguisher must be recharged using the extinguishing agent specified on the nameplate. Substitutions could cause damage or injury.
It is now required for extinguishers to have collars or rings attached to the neck or another part of the fire extinguisher in order to verify that the unit was serviced. The Fire Shop accommodates walk-in fire extinguisher service, as well as dry chemical suppression systems. Please contact us to learn more or to schedule service.
