Chemical Segregation: Why It Matters and How to Do It Right

Written by Phil John | Jun 26, 2025 4:33:42 AM

 

Chemical segregation is the separation of incompatible substances such as acids, bases, flammables, and oxidisers, to prevent dangerous reactions, fires, and spills in labs, warehouses, and workplaces.

Risks of Poor Segregation

  • Reactive hazards: Mixing oxidisers and organics or acids and bases can create heat, flames, toxic gases, or even explosions.

  • Environmental spill risks: Chemical releases can contaminate drains and soil.

  • Regulatory breaches: In Australia, the ADG Code and AS 4452 mandate strict segregation of hazardous substances.

Australian Standards & Regulations

  • AS 4452:1997 (Storage and Handling of Toxic Substances) outlines the requirements for the safe storage and handling of toxic substances classified as Class 6.1 under the Australian Dangerous Goods (ADG) Code. It includes specifications such as the use of metal cabinets for storing highly toxic chemicals like cyanides and phenols.

  • ADG Code (Australian Dangerous Goods Code): Establishes the rules and guidelines for the classification, packaging, labelling, and transport of dangerous goods by road and rail in Australia.

  • Labeling and signage: Clear signage is required for effective chemical segregation in Australian workplaces. It ensures legal compliance, enhances safety, and supports emergency response. Safety signs such as "Chemical Storage Area" reduces misidentification.

Practical Strategies for Segregation

Category

Recommended Storage

Flammable liquids

Store in dedicated flammable cabinets, away from ignition sources.

Corrosives

Store in separate cabinets with acid/base trays and spill containment.

Toxics

Store in AS 4452-compliant toxic substance cabinets such as SAYKA’s Stortekt 250L container.

Class 4 Solids

Store in specialised flammable solids units as per Class 4 cabinet specs.

Oxidisers

Isolate from organics in vented, stainless cabinets.

Spill kit & bunding

Store nearby in labelled spill kits such as the Spillfixr 80L Kit and bunded pallets.

 

Best Practice Implementation Tips

  1. Assess chemical inventory: Map quantities, hazard classes, incompatibilities.

  2. Label everything clearly: For example, “Toxic”, “Flammable”, “Corrosive”.

  3. Select proper storage equipment: Such as SAYKA’s Stortekt cabinets, matching class & volume.

  4. Use bunding mechanisms: Spillfixr bunded pallets help contain leaks.

  5. Equip spill kits: Place near storage zones based on hazard type.

  6. Regular training & audits: Staff must be competent in segregation, storage, and response.

Why Segregation Is Worth It

  • Reduced incident rates: Lower chance of dangerous chemical mixing or spills.

  • Legal compliance: Avoid hefty fines, work-safe enforcement, and environmental liabilities.

  • Protect your team & environment: Limits exposure and mitigates contamination risks.

  • Operational efficiency: Clearly designated areas speed up workflows and inspections.

Effective chemical segregation goes beyond compliance - it’s foundational to a safe and efficient workplace. 

By investing in proper cabinets, like SAYKA’s Stortekt range, and also bunded pallets, spill kits, clear signage, and staff training, you can significantly reduce hazards and foster a culture of safety.
