Chemical Handling SWMS

Chemical handling in manufacturing encompasses receiving, storing, decanting, mixing, using, and disposing of hazardous chemicals across the full production lifecycle. The incoming WEL reductions for styrene, isocyanates, formaldehyde, and numerous other substances mean that chemical handling procedures must be reviewed against the new limits. Chemical incompatibility during storage, toxic gas generation during mixing, and skin sensitisation from contact with epoxies and isocyanates are hazards that require specific controls beyond general PPE provision. This template maps controls to the binding Managing Risks of Hazardous Chemicals Code of Practice effective 1 July 2026 under Section 26A.

Legal Requirements

code of practice

Managing Risks of Hazardous Chemicals in the Workplace (binding 1 July 2026 under Section 26A)

section 26a binding

Yes — effective 1 July 2026. Non-compliance is admissible as evidence of breach.

Hazards

Hazard	Consequence	Likelihood
Inhalation of chemical vapours and fumes above WEL	Acute poisoning, chronic respiratory disease, cancer	Likely
Chemical burns from corrosive substances during decanting	Severe skin and eye burns, permanent eye damage	Possible
Chemical incompatibility reaction during storage or mixing	Fire, explosion, toxic gas release	Unlikely
Skin sensitisation from isocyanate, epoxy, or formaldehyde contact	Occupational dermatitis, respiratory sensitisation	Likely
Fire or explosion from flammable chemical vapour accumulation	Flash fire, explosion, severe burns, death	Possible
Environmental contamination from chemical spill	Regulatory prosecution, cleanup costs, community harm	Possible

Controls (Hierarchy of Controls)

Maintain a current chemical register with Safety Data Sheets for every chemical on site

Store chemicals according to the GHS segregation requirements with incompatible chemicals separated

Provide local exhaust ventilation at decanting stations and mixing areas

Fit-test appropriate RPE for workers handling chemicals with exposure above the applicable WEL

Provide chemical-resistant gloves matched to the specific chemicals being handled using SDS permeation data

Install emergency eyewash stations and safety showers within 10 seconds travel of chemical handling areas

Implement spill response procedures with appropriate spill kits for each chemical category

Conduct personal exposure monitoring for substances with incoming WEL changes to verify compliance
