Portable fire extinguishers must be installed in all workplaces regardless of whether other fire protection measures are present. As an early response to a developing fire, the successful performance of a fire extinguisher depends on appropriate placement, proper maintenance and trained users.

There are different types of extinguishers, each designed to extinguish a specific class of fire. They are selected according to the potential fire hazard, the construction & occupancy of the building, and the asset to be protected.

The different classes of extinguishers are:

  • Class A – Ordinary Combustible Solids: Wood, paper, cloth, plastics, rubber, coal, carbon based compounds
  • Class B – Flammable & Combustible Liquids: Petrol, oil, paint, thinners, kerosene, alcohol
  • Class C – Flammable Gases: L.P.G., Butane, Acetylene, Hydrogen, natural gas and Methane
  • Class D – Combustible Metals: Magnesium, aluminium, sodium or potassium
  • Class E – Electrically Energised Equipment: Computers, switchboards, power-boards
  • Class F – Cooking Oils and Fats: Cooking oils and fats usually found in industrial kitchens

Stevnor Services sells, tests and services fire extinguishers for all classes of fire. In addition to maintaining an extensive inventory of new extinguishers, our highly trained technicians inspect, certify and repair them in strict adherence to AS 1851. We can also sell, test and service other portable equipment including lay flat hoses & hose reels as well as ensuring your building has the appropriate signage for your portable equipment.

It is imperative that fire extinguisher maintenance is carried out regularly to ensure that the equipment will work when you need it most. After an extinguisher has been used, even if only partially, it must be recharged or replaced and all extinguishers should be fully serviced each six months to comply with the requirements of AS1851.
