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

Hazards

Hazard	Consequence	Likelihood
Glutaraldehyde vapour inhalation during instrument reprocessing	Respiratory sensitisation, occupational asthma, skin sensitisation	Possible
Peracetic acid splash during automated endoscope reprocessing	Severe chemical burns to skin and eyes	Possible
Chlorine gas release from mixing incompatible cleaning products	Acute respiratory distress, chemical pneumonitis	Unlikely
Skin irritation and dermatitis from repeated disinfectant contact	Contact dermatitis, chronic skin condition	Likely
Quaternary ammonium compound inhalation from spray application	Respiratory irritation, occupational asthma	Possible

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
