ABC Dry Chemical Fire Extinguishers

ABC Dry Chemical Fire Extinguishers are the most common Fire Extinguisher and 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 and are not recommended to be used on computers or other sensitive equipment or machinery which may be damaged by the powder

  • Home
  • Office
  • Sleeping Areas
  • Home Kitchen (not commercial kitchens)
  • Outdoor Shed
  • Garage

Class K Fire Extinguishers

Class K Fire Extinguishers are REQUIRED to be located in all commercial kitchens, these extinguishers are designed to put out cooking oil and grease fires.
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 do not leave a harmful residue.

  •  Computer Rooms

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

  • 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.

Monthly Visual Inspections

Monthly and annual inspections are the best ways to ensure your fire extinguisher operates effectively and is stored and mounted properly. The monthly inspections are visual only and can be performed by the homeowner or a company's maintenance or safety personnel. These inspections ensure the extinguisher is undamaged, the hose is not blocked, the safety seal is unbroken and the operating instructions are legible.

They also include a check of the pressure gauge to verify the device is fully charged. The month and year of these inspections, along with the initials of the person performing them, are recorded on the extinguisher's hang tag.

Annual Maintenance of Fire Extinguishers

Annual Inspections are more thorough and must be completed by a licensed professional, since annual maintenance must include an examination of the mechanical parts, the fire-suppression agent and the delivery system. The certification of these inspections must be recorded on the Fire Extinguisher Tag, including the inspection date and the inspector's initials.

Six-Year Inspections

Six-year maintenance inspections are much like the annual inspections. The main difference is that during the six-year inspections, stored-pressure Fire Extinguishers are emptied of contents. A licensed professional must examine the mechanics, outlet hose and delivery system, after which the extinguisher is refilled, re-pressurized and marked with a tamper-resistant seal.

These six-year inspections must be recorded on the regular hang tag and on a separate metallic label attached to the body of the extinguisher. Notations must include the month and date of the inspection, as well as the inspector's name and company affiliation.

Hydrostatic Materials Inspections

Hydrostatic materials inspections are required at varying intervals. Five-year inspections are required for all pressurized water, carbon dioxide and wet-chemical extinguishers, while dry-chemical extinguishers must be inspected every 12 years. These inspections use water or another fluid to pressurize the extinguisher cylinder to verify it still meets factory standards.

Hydrostatic inspections must be carried out by professionals with particular training in handling the fire-extinguishing agents. They must recharge and seal the extinguisher as soon as the hydrostatic testing is done. Five-year and 12-year inspections are recorded on the hang tag and the permanently attached metal tag on the cylinder. Inspectors must note the date, their name and company affiliation, the fire extinguisher's pressure level and the extinguishing agent used.
