Category 4 flammable liquids as defined in the GHS overlap with C1 combustibles, as defined in the Australian Standard AS 1940:2017. NOTE: GHS categories 1 to 3 are the same as the ADG Code for packing groups I to III. Therefore, it’s important the control measures are in place to minimise risk in your workplace. When you’re dealing with flammable liquids with a very low flash point, there can be a greater risk of fire, explosion and human harm. However, any flammable liquid, regardless of its flash point, has the chemical properties to ignite in the presence of an ignition source. The following explains the GHS category criteria for this chemical type: This system classifies flammable liquids into one of 4 categories - as defined by their flashpoint. The Globally Harmonised System (GHS) is a classification and labelling system that can help you responsibly store and handle your flammable liquids. The flammability of each flammable liquid also varies, so it’s essential that you check the Safety Data Sheet for each chemical to determine the safe storage and handling guidelines for its use. Some highly volatile flammable liquids include petrol and diesel fuel, while less volatile flammable liquids include substances such as diethyl ether and carbon disulphide. Due to this risk of fire (or explosion), it’s vital that anyone handling or storing flammable liquids is trained to identify and eliminate ignition sources.įlammable liquids are defined by their flash point and ability to ignite easily in the presence of an ignition source. If flammable liquids meet an ignition source, they will ignite easily and burn fast. Many everyday objects, like a cigarette lighter or an electric lamp, can be ignition sources. The flash point is the lowest possible temperature for vapor from a flammable liquid to ignite when triggered by an ignition source. Liquid state and which give off a flammable vapour at a temperature at or below the maximum transport temperature.Īs you can see from the above definition, the key chemical property that defines a flammable liquid is the substance’s flash point. (b) substances that are transported or offered for transport at elevated temperatures in a (a) liquids offered for transport at temperatures at or above their flash point and The Australian Dangerous Goods (ADG) Code provides us with a detailed definition of flammable liquids:įlammable liquids are liquids, or mixtures of liquids, or liquids containing solids in solution or suspension (for example, paints, varnishes, lacquers, etc., but not including substances otherwise classified on account of their dangerous characteristics) which give off a flammable vapour at temperatures of not more than 60 ☌, closed-cup test, or not more than 65.6 ☌, open-cup test, normally referred to as the flash point. To help your organisation stay safe and compliant, we’ll be answering the question, ‘ What is a flammable liquid’, and offering advice on how to avoid the risks and hazards that are associated with carrying this substance in your workplace. As a class of Dangerous Goods that’s widely used across a broad range of Australian workplaces, flammable liquids are an essential product - but also a hazardous one. If you work with any kind of flammable liquid - whether it’s in a manufacturing facility, a laboratory or a mechanical workshop - you probably are already aware of how important it is to handle and store t he chemical safely.
