AS 1841- General

Generally, AS1841 is utilized by fire extinguisher companies that are looking to develop their own extinguishers and have them rated.

From a service point of view AS1851 is the standard that explains all the ins and outs of fire testing while AS2444 is the installation standard of fire extinguishers. A building certifier or fire portables certifier will determine the location of the portable equipment, along with the risk and volume of potential fire risk. Legislation in all Australian states requires a competent person to complete this.

Ongoing Fire Extinguisher Maintenance to AS1851-2012

Once a fire extinguisher has been installed, certified and is in the maintenance period of AS1851- 2012 Section 10, the following testing frequency is required;

  • Six monthly
  • Annually
  • Five Yearly

Each test performed requires a different type of inspection, and different types of extinguishers require different tests. Although water and foam extinguishers are similar, the testing for each does differ.

Due to the risk of injury or even death by incorrect testing of fire extinguishers, it is highly recommended to only use a fire service professional for your routine inspections.

FCF Fire & Electrical’s recommendation is to purchase from a fire service company. Buying fire extinguishers online does not meet the requirements of AS2444 or AS1851. In many cases, consumers have tried to save a couple of dollars without understanding the fire legislation and as a result end up leaving their businesses, as well as other people and property at risk, also leaving themselves open to litigation or insurance claim rejections.
