Hazardous spill response covers the containment, neutralisation and clean-up of uncontrolled releases of dangerous goods, hazardous chemicals, fuels, acids, alkalis and other regulated substances on Australian workplaces. The work involves rapid bunding deployment, absorbent application, exclusion zoning, evacuation coordination, atmospheric monitoring and contaminated waste packaging — each step exposing responders to inhalation, dermal, fire and environmental hazards. Under WHS Regulation 2025 (and harmonised state instruments), spill response that involves Schedule 11 hazardous chemicals, work in confined or oxygen-deficient atmospheres, or interaction with energised plant constitutes High Risk Construction Work or notifiable hazardous work, mandating a documented Safe Work Method Statement before work commences. Sections 19 and 274 of the model WHS Act place a primary duty on the PCBU to identify hazards, apply the hierarchy of control, consult workers, and document the method. This SWMS provides the controlled, signed-on, site-specific record required to discharge that duty and to satisfy regulator inspection during or after a spill incident.
Hazards identified
7 hazards covered, sorted by priority.
Acute chemical pneumonitis, pulmonary oedema, central nervous system depression and long-term respiratory sensitisation requiring hospitalisation
Flash fire, vapour cloud explosion, full-thickness burns and structural fire damage triggering notifiable incident under s38
Full-thickness chemical burns, corneal ulceration, permanent scarring and potential systemic absorption through compromised skin
Exothermic reaction, toxic gas evolution (chlorine, hydrogen sulphide, cyanide) and pressurised drum rupture causing secondary release
Falls onto contaminated surface causing immersion exposure, fractures and lost-time injury exceeding seven days
EPA prosecution under state Protection of the Environment legislation, clean-up orders and remediation costs in addition to WHS penalties
Core temperature elevation, syncope, impaired decision-making and rhabdomyolysis during prolonged response in encapsulating PPE
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where feasible, decant or transfer remaining product back to bulk storage by closed-loop pump before commencing manual absorbent clean-up to remove the source.
- 2Elimination — Isolate and lock out all ignition sources, plant and powered equipment within a 15 m radius of flammable spills before any responder enters the exclusion zone.
- 3Substitution — Replace clay-based absorbents with neutralising or reactive absorbents (e.g. SpillFix, neutralising pillows) matched to the SDS chemical class to reduce reactive risk.
- 4Substitution — Use polypropylene drum overpacks rated UN X1.8 in place of open-top steel drums for contaminated absorbent to remove corrosion-driven secondary release.
- 5Engineering — Deploy portable bunding, drain covers and inflatable stormwater plugs from the spill kit within 60 seconds of detection to prevent migration per AS 3780.
- 6Engineering — Establish forced-ventilation or extraction at the spill perimeter and use a calibrated four-gas monitor (LEL, O2, H2S, CO) before and during entry.
- 7Administrative — Conduct a pre-entry SWMS sign-on, confirm SDS review, verify chemical compatibility matrix, and nominate a standby observer with radio communication outside the zone.
- 8Administrative — Limit responder rotation to 20-minute work cycles in encapsulating PPE with mandatory rest, hydration and physiological monitoring per AS/NZS 1715.
- 9PPE — Issue chemical splash suits to AS/NZS 4501.2, gloves to AS/NZS 2161.10.1 matched to permeation data, and full-face respirators with appropriate ABEK-P3 cartridges.
- 10PPE — Provide emergency eyewash and safety shower within 10 seconds travel of the work zone compliant with AS 4775, plus chemical-resistant boots to AS/NZS 2210.3.
Applicable Codes of Practice
Sets the duty to identify, assess and control hazardous chemical risks including spill preparedness, SDS access and emergency planning under WHS Regulation Part 7.1.
Mandates fit-testing, cartridge selection and program elements for the air-purifying and supplied-air respirators required during volatile chemical spill response.
Specifies bunding capacity, compatibility segregation and spill containment performance directly referenced when sizing portable bunding deployed in this SWMS.
Defines performance classes for chemical splash suits and aprons selected against the permeation and breakthrough data on the hazardous chemical SDS.
High-Risk Construction Work triggered
Responders make direct contact with Schedule 11 hazardous chemicals during containment and clean-up, exceeding the workplace exposure standard threshold without engineering controls.
Spill response in bunded tank compounds, pits and process areas regularly meets the confined space definition under WHS Regulation r66 during entry.
Volatile flammable liquids generate atmospheres exceeding 5% LEL near the spill, classifying the response as work in a flammable atmosphere requiring controlled entry.
PCBU must consult workers, document the SWMS before work, retain it for two years (or until incident closure), and produce it on regulator request; penalties are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
At a regional fuel depot, a forklift punctures a 200-litre drum of sulphuric acid solution, releasing approximately 80 litres across the loading bay. The shift supervisor activates the spill alarm, evacuates non-essential workers upwind to the muster point, and convenes the trained response team at the equipment cache. Before any responder approaches the release, the supervisor opens the Hazardous Spill Response SWMS on the bay tablet and walks the two-person entry team through the hazard register — focusing on dermal corrosive contact, hydrogen evolution if the acid contacts aluminium pallets, and stormwater migration toward the adjacent drain. The SWMS control matrix directs the team to deploy the polypropylene drain cover first, then place neutralising absorbent (calcium carbonate granules) from the perimeter inward, confirming compatibility against the SDS already pinned to the document. Each responder signs onto the SWMS, records their respirator fit-test date and glove permeation rating, and the nominated standby observer takes position outside the zone with the four-gas monitor. Fifteen minutes into the clean-up, the gas monitor alarms on rising hydrogen near a damaged pallet. The supervisor pauses the task, annotates the SWMS dynamic-risk section, adds removal of metallic debris as an additional control, re-briefs the team, and resumes. The completed SWMS, with sign-ons and the field amendment, is filed for regulator inspection.
