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.

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

Hazards

Hazard	Consequence	Likelihood
Chemical burns from caustic soda or acid splash	Severe skin and eye burns, permanent eye damage	Likely
Chlorine gas release from mixing hypochlorite with acid	Acute respiratory distress, pulmonary oedema, death	Possible
Inhalation of chemical vapours during manual cleaning	Respiratory irritation, chemical pneumonitis	Likely
Formaldehyde exposure from formaldehyde-based sanitisers	Respiratory sensitisation, nasal cancer	Possible
Slip and fall on wet chemical-treated floors	Fractures, chemical contamination of injuries	Likely
Skin sensitisation from repeated chemical contact	Occupational dermatitis, chronic skin conditions	Likely

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
