CLASS 3 - FLAMMABLE LIQUIDS

Note: The following description is not intended to be a definitive technical description of what is termed a dangerous goods under the New Zealand Standard 5433:1999 - Transport of Dangerous Goods on Land or The United Nations Recommendations on the Transport of Dangerous Goods.

Flammable liquids, as the name implies, are liquids which burn. Note however, it is not the liquid itself that burns, but the chemical's vapour above the liquid. In general, the easier it is to get the liquid to burn the higher the hazard. This will be a function of the physical and chemical properties of the liquid. In general, two simple measurements are used to determine whether a liquid is flammable or not, the flash point and the boiling point.

Examples of flammable liquids include

• Petrol/gasoline
• Alcohols
• Solvents e.g. benzene
• Thinners

Flammable Liquids are identified by the following label: Flammable liquids once they are are burning will cause many normally stable materials (eg wood) to burn. They can cause other packagings to burn and with the extreme heat, cause failure in the bottles, tins and drums containing other dangerous goods which may include more flammable liquids.

Burning materials produce large quantities of smoke which may be toxic (eg, burning plastic) and is oxygen deficient.
