Fire Extinguisher Inspections, Recharging & other Services
Fire is the third leading cause of accidental deaths in the United States, yet most people ignore it. More than 150 workplace fires occur every day.
ABC Dry Chemical Fire Extinguishers are rated to extinguish fires caused by paper, wood, burning liquids and energized electrical equipment. They are suitable for most environments in fire fighting and are the most common and cost-effective fire extinguisher. ABC Dry Chemical powder is non-toxic, but does leave a dusty residue if used or discharged. ABC Dry Chemical fire extinguishers are not recommended to be used on computers or other sensitive equipment or machinery which may be damaged by the powder.
Areas to use ABC Dry Chemical Fire Extinguishers:
-
Home
-
Office
-
Sleeping Areas
-
Home Kitchen (not commercial kitchens)
-
Outdoor Shed
-
Garage
K Class Fire Extinguishers.
This is the fire extinguisher REQUIRED to be located in all commercial kitchens..
These extinguishers are designed to put out cooking oil and grease fires.
Areas to use K Class Wet Chemical Fire Extinguishers:
-
Commercial Kitchen
CO2 Fire Extinguishers
CO2 Extinguishers contain carbon dioxide, a non-flammable gas, and are highly pressurized.
These extinguishers are a good choice for an area or office where an electrical fire might occur
because they don’t leave a harmful residue.

Fire Extinguisher Maintenance
-
Recharging - needs to be performed after each use or if the gauge is not in the green area.
-
Internal Maintenance: [ 6 year Inspection ]
Wet chemical & CO2 - every 5 years
Dry chemical -every 6 years
-
The extinguisher is emptied of its chemical and pressure to check for proper operation. All components are disassembled, inspected, cleaned, lubricated, or replaced if defective. Liquid agents are replaced at this time, dry agents may be re-used if in good condition, but CO2 is discharged into the atmosphere. The extinguisher is then re-filled and recharged, after a "verification of service" collar is placed around the cylinder neck. It is impossible to properly install or remove a collar without depressurizing the extinguisher.
Note: Cartridge-operated extinguishers are visually examined, but do not require a verification of service collar.
-
Hydrostatic testing: [ 12 year Inspection]
Wet chemical, and CO2, every 5 years
Dry chemical, dry powder, every 12 years
-
The agent is emptied and depressurized and the valve is removed. After a thorough internal and external visual inspection, the cylinder is filled with water, placed inside a safety cage, and pressurized to the specified test pressure (varies with the type, age, and cylinder material) for the specified time period. If no failure, bulges, or leaks are detected, the cylinder passes. The cylinder is then emptied of water and thoroughly dried. A new sticker is put on the back of the extinguisher showing the date the test was performed.
Note: these are the required intervals for normal service conditions, if the extinguisher has been exposed to excessive heat, vibration, or mechanical damage it may need to be tested sooner.
Types of Fire Extinguishers:
Water and Foam
Water and Foam fire extinguishers extinguish the fire by taking away the heat element of the fire triangle. Foam agents also separate the oxygen element from the other elements.
Water extinguishers are for Class A fires only - they should not be used on Class B or C fires. The discharge stream could spread the flammable liquid in a Class B fire or could create a shock hazard on a Class C fire.
Carbon Dioxide
Carbon Dioxide fire extinguishers extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge.
Carbon dioxide can be used on Class B & C fires. They are usually ineffective on Class A fires.
​
Dry Chemical
Dry Chemical fire extinguishers extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
Today's most widely used type of fire extinguisher is the multipurpose dry chemical that is effective on Class A, B, and C fires. This agent also works by creating a barrier between the oxygen element and the fuel element on Class A fires.
Ordinary dry chemical is for Class B & C fires only. It is important to use the correct extinguisher for the type of fuel! Using the incorrect agent can allow the fire to re-ignite after apparently being extinguished succesfully.
Wet Chemical
Wet Chemical is a new agent that extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements.
Wet chemical of Class K extinguishers were developed for modern, high efficiency deep fat fryers in commercial cooking operations. Some may also be used on Class A fires in commercial kitchens.
