Flammable vs Corrosive vs Toxic Cabinets: What's the Difference?
If you're storing hazardous chemicals in an Australian workplace, selecting the correct storage cabinet is an important part of safe chemical management. However, many businesses are unsure whether they require a flammable liquid cabinet, corrosive substance cabinet or toxic substance cabinet.
While these cabinets can appear similar at first glance, they are designed for different Dangerous Goods classifications and storage requirements.
Understanding the differences between Class 3 flammable liquids, Class 8 corrosive substances and Class 6 toxic substances can help ensure chemicals are stored appropriately and safely within the workplace.
Understanding Dangerous Goods Classes
In Australia, hazardous chemicals are classified according to their physical and health hazards. These classifications help determine how chemicals should be handled, transported and stored.
Three of the most commonly stored dangerous goods in Australian workplaces include:
Class 3 – Flammable Liquids
Class 3 dangerous goods are liquids that can ignite easily when exposed to an ignition source.
Common examples include:
- Petrol
- Acetone
- Ethanol
- Methylated spirits
- Paint thinners
- Solvents
- Adhesives
Because these products present a fire risk, they should be stored in cabinets specifically designed for flammable liquids.
Class 8 – Corrosive Substances
Class 8 dangerous goods are substances capable of causing damage to skin, equipment, metals and other materials through chemical action.
Common examples include:
- Hydrochloric acid
- Sulfuric acid
- Nitric acid
- Caustic soda
- Sodium hydroxide
- Industrial cleaning chemicals
Corrosive substances require storage solutions designed to help manage spills and withstand exposure to aggressive chemicals.
Class 6 – Toxic Substances
Class 6 dangerous goods are substances that may cause injury or adverse health effects through inhalation, ingestion or skin contact.
Common examples include:
- Certain pesticides
- Agricultural chemicals
- Laboratory reagents
- Industrial poisons
- Treatment chemicals
These substances typically require secure storage with controlled access and clear hazard identification.

Can Different Dangerous Goods Classes Be Stored Together?
Generally, dangerous goods should be stored according to their classification and chemical compatibility.
For example, flammable liquids and corrosive substances present different hazards and are typically stored in dedicated cabinets designed for their specific dangerous goods class.
Before storing multiple chemicals together, it is important to review:
- The Safety Data Sheet (SDS)
- Chemical compatibility information
- Workplace risk assessments
- Applicable Australian Standards
Where uncertainty exists, always consult the chemical manufacturer or a qualified hazardous goods specialist.
Which Cabinet Do I Need?
The easiest way to determine the correct cabinet is to identify the dangerous goods classification of the chemical being stored.
This information can usually be found on:
- Product labels
- Safety Data Sheets (SDS)
- Manufacturer documentation
Once the classification has been identified, the appropriate storage cabinet can be selected.
| Dangerous Goods Class | Typical Chemicals | Recommended Cabinet |
|---|---|---|
| Class 3 | Petrol, solvents, paints, fuels | Flammable Liquid Cabinet |
| Class 8 | Acids, alkalis, cleaning chemicals | Corrosive Substance Cabinet |
| Class 6 | Pesticides, poisons, toxic chemicals | Toxic Substance Cabinet |
