Cleaning Chemical Use SWMS

Food processing facilities use concentrated cleaning chemicals including sodium hydroxide (caustic soda), phosphoric acid, peracetic acid, sodium hypochlorite, and quaternary ammonium compounds for equipment sanitisation and CIP cleaning. These chemicals cause severe chemical burns on skin contact, eye damage on splash, and toxic gas generation if incompatible chemicals are mixed. Chlorine gas is released when hypochlorite contacts acid cleaners — a mixing error that has caused multiple worker hospitalisations in Australian food processing facilities. The formaldehyde WEL drops from 1 to 0.3 ppm affecting facilities using formaldehyde-based sanitisers. This template maps controls to the binding Hazardous Chemicals Code of Practice effective 1 July 2026.

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

HazardConsequenceLikelihood
Chemical burns from caustic soda or acid splashSevere skin and eye burns, permanent eye damageLikely
Chlorine gas release from mixing hypochlorite with acidAcute respiratory distress, pulmonary oedema, deathPossible
Inhalation of chemical vapours during manual cleaningRespiratory irritation, chemical pneumonitisLikely
Formaldehyde exposure from formaldehyde-based sanitisersRespiratory sensitisation, nasal cancerPossible
Slip and fall on wet chemical-treated floorsFractures, chemical contamination of injuriesLikely
Skin sensitisation from repeated chemical contactOccupational dermatitis, chronic skin conditionsLikely

Controls (Hierarchy of Controls)

Maintain a current chemical register with Safety Data Sheets for every cleaning product on site
Implement chemical incompatibility procedures preventing acid and hypochlorite contact
Provide chemical-resistant gloves, aprons, and face shields for all chemical handling tasks
Install emergency eyewash stations and safety showers within 10 seconds travel of chemical use areas
Use enclosed chemical dosing systems for CIP cleaning to minimise manual chemical handling
Ensure ventilation is adequate in areas where chemicals are used manually — open doors and activate extraction
Train all workers in chemical hazard identification, SDS interpretation, and emergency spill procedures
Substitute formaldehyde-based sanitisers with less hazardous alternatives where disinfection efficacy permits
