AS 1851 Requirements

Portable fire extinguishers are used to put out small fires. They are classified according to the type of fire they can put out, and include water, foam, powder (dry chemical), carbon dioxide, and vaporizing types.

Reference“Knowing Your Fire Classes & Extinguishers”

Most common in modern workplaces are ABE (automatic bicarbonate extinguishers) and CO2 fire extinguishers. A food business will also have a wet chemical fire extinguisher for fat fires.

The frequency of inspection and maintenance can vary from monthly to yearly to five-yearly depending on the type of extinguisher you use. At the five-year mark when an extinguisher is due for a pressure test the common result is to replace it with a new one because it’s cheaper than refurbishing them—each extinguisher can vary depending on the build quality of the unit, however, so many manufacturers only ensure that its cylinder quality lasts five years before melting it down into a new unit.

AS 1841 (General)

In Australia, the AS1841 and AS2444 standards are used by fire extinguisher companies that are looking to develop their own extinguishers. The two standards explain all the ins and outs of fire testing, while the AS1851 standard explains all the ins and outs of installing fire extinguishers.

A building certifier or fire portables certifier will determine where to locate your portable equipment along with their risk level and volume of potential fire risk. Legislation in all Australian states requires a competent person to complete this process.
