Can you store Class 3 Flammable Liquids with Class 8 Corrosive Substances?

Feb 1, 2019 Posted by Walter Ingles

When storing and handling chemicals and dangerous goods in the workplace, it is important that this is conducted in accordance to AS3833-2007 The Storage and Handling of Mixed Classes.

As AS3833-2007 outlines, Class 3 Flammable Liquids and Class 8 Corrosive Substances should not be stored together. Measure should be taken to ensure that chemicals of these two classes are not stored together as Class 3 Flammable liquids and Class 8 Corrosive substances are incompatible substances.

When these chemicals mix, they can react to form large quantities of gas. This gas can be toxic or flammable and can have dangerous implications upon people in the immediate area. If flammable gas develops,  there is potential that the flammable gas could come into contact with an ignition source, which could cause an explosion or severe fire. If toxic gas is evolved and inhaled, it can have very severe effects upon human health including suffocation and burning of internal organs.

Therefore, when you are using a number of different chemicals and dangerous goods in the workplace it is very important that you ensure that you are aware, or consult someone who is aware, of the requirements of segregation set out in AS3833-2007. This knowledge, coupled with an understanding of the chemical and physical properties of the substances that you are using and their Dangerous goods classification, will enable you to take certain measures to ensure that Class 3 Flammable liquids and Class 8 Corrosive substances are not stored together. In turn, this will minimise the risk of these two incompatible substances mixing and reacting in a violent manner and provide a safer workplace for people and the environment.
