ADR Training – Class 3 Flammable Liquid

The ADR qualification is required for drivers who transport dangerous goods. These are goods ‘classified’ as dangerous by the ADR Agreement itself.

Drivers are required to be qualified, and hold the certificate for, the relevant modules for the goods they will be transporting. These modules are Core, Packages, Tanks, Classes 1 – 9.

In this article we will discuss the Class 3: Flammable Liquid module.

When transporting dangerous goods that are primarily classified as Class 3: Flammable Liquid, drivers are required to hold an ADR certificate that includes the Class 3 module.

The Class 3 module gives drivers an understanding of the different terms used to describe the dangers of Flammable Liquids. These include Flashpoint and Auto-ignition. Flammability Limits is also discussed as well as vapour volumes/ratios.

The Class 3 module includes:

• Characteristics of Class 3 materials
• Marking and Labelling
• Dangers and precautions to be exercised when transporting flammable liquids
• Volatility
• Vapours above the liquid burn rather the liquid themselves
• Vapours are usually colourless and heavier than air increasing the risk of asphyxiation and/or fire
• Possible subsidiary hazards including toxicity and corrosivity
• Segregation methods and responsibilities of all persons involved
• Flashpoint, auto-ignition temperature, flammability limits and liquid to vapour volumes/ratios
• Combination of vapour, air and ignition source can create fire hazards
• Miscibility and immiscibility
• Containment of material and actions on exposure to flammable liquids
• Source of ignition
• Appropriate PPE to include respiratory protective equipment (RPE)

The full syllabus and more details can be found in the ADR Course Guide.

The Class 3: Flammable Liquid module must be passed by drivers who transport goods classified as Class 3 in ADR. These can include items such as Petrol, Diesel (Gas Oil) and Kerosene.

In order to obtain the ADR certificate, at least one Class module must be taken.
