A flammable liquid is a liquid that has the potential to ignite at temperatures below 62°C. This ignition temperature is the liquid's flash point.
A common example of a flammable liquid is Unleaded Petrol.
A combustible liquid is a liquid which has the potential to ignite or combust. It is defined as being a liquid other than a flammable liquid which has an ignition point less than its boiling point. The temperature at which ignition occurs, is known as the liquids flash point.
A common example of a combustible liquid is diesel fuel.
As of the 1st January 2012, the Dangerous Goods Safety Management (DGSM) Act 2001 was repealed. The repeal of the dangerous goods legislation resulted in the abolition of the flammable and combustible liquids (FCL) licences administered by local governments. This means that all FCL licences ceased to have effect after 31 December 2011. There is no power for local government to issue FCL licences after this date. The storage of dangerous goods is now regulated by the Queensland Work Health and Safety (WHS) Act 2011. Council planning schemes may contain provisions relating to the design and location of flammable and combustible liquid storage facilities, which aim to minimise the risk to the community from hazardous chemicals.
