Chemical Disinfection SWMS

Chemical disinfection in healthcare settings exposes workers to respiratory sensitisers, skin irritants, and toxic vapours from products including glutaraldehyde, peracetic acid, sodium hypochlorite, and quaternary ammonium compounds. Glutaraldehyde — used for high-level disinfection of endoscopes and surgical instruments — is one of the most potent respiratory sensitisers in any workplace and has a workplace exposure limit of 0.05 ppm ceiling. Workers in endoscopy suites, sterile services departments, and dental surgeries face the highest exposure concentrations. This template covers all chemical disinfection procedures with controls mapped to the binding codes effective 1 July 2026.

Legal Requirements

WHS Regulation 2025 Part 7.1 — Hazardous Chemicals

hrcw category

Work involving hazardous chemicals (disinfectants, sterilants)

code of practice

section 26a binding

Yes — Hazardous Chemicals code binding July 2026. Non-compliance is admissible as evidence of breach.

Hazards

HazardConsequenceLikelihood
Glutaraldehyde vapour inhalation during instrument reprocessingRespiratory sensitisation, occupational asthma, skin sensitisationPossible
Peracetic acid splash during automated endoscope reprocessingSevere chemical burns to skin and eyesPossible
Chlorine gas release from mixing incompatible cleaning productsAcute respiratory distress, chemical pneumonitisUnlikely
Skin irritation and dermatitis from repeated disinfectant contactContact dermatitis, chronic skin conditionLikely
Quaternary ammonium compound inhalation from spray applicationRespiratory irritation, occupational asthmaPossible

Controls (Hierarchy of Controls)

Use enclosed automated reprocessing systems for glutaraldehyde and peracetic acid wherever feasible
Provide local exhaust ventilation over manual disinfection sinks and reprocessing areas
Substitute glutaraldehyde with less hazardous alternatives (peracetic acid systems, ortho-phthalaldehyde) where clinically acceptable
Require chemical-resistant gloves, apron, and eye protection for all manual disinfection tasks
Prohibit spray application of disinfectants in enclosed spaces — use wipe application instead
Display incompatibility charts to prevent mixing of chlorine and acid-based products
Conduct air monitoring in reprocessing areas to verify exposure below glutaraldehyde ceiling limit

Recent Prosecutions

WorkSafe Victoria v Day Surgery Centre$175,000

Endoscopy reprocessing staff developed occupational asthma from glutaraldehyde exposure. Facility used open-tray manual reprocessing without LEV and did not provide health monitoring.

What Your SWMS Must Include

✓Disinfectant product selection with hazard comparison and substitution assessment
✓Ventilation requirements for each reprocessing and disinfection location
✓PPE specification for each disinfectant product and application method
✓Chemical incompatibility controls to prevent accidental toxic gas generation
✓Air monitoring program for glutaraldehyde and other respiratory sensitisers
