Fire and explosion in a feed mill, documented end to end.
The NSW documents for combustible dust across the whole mill — receival, elevators, grinding, mixing, pelleting, cooling, dust collection, storage and load-out. A process-unit risk assessment plus the four instruments its controls point at — so the mill can start now instead of waiting months for a specialist to become available.

The documented system, not just the method
A feed mill supplies every condition for a dust explosion as a matter of routine. Every transfer point makes a cloud; every bucket elevator leg, hammer-mill housing, bin and dust collector is a confined volume; bearings, belts, tramp metal, hot work and electrical equipment are ignition sources. Under the WHS Regulation 2025 (NSW) an atmosphere is a hazardous atmosphere where combustible dust is present in a quantity and form that would result in a hazardous area (s 51), the risks from ignition sources in it must be managed (s 52), combustible material must be kept to the lowest practicable quantity (s 53), and an ignition source must not be introduced where it could cause fire or explosion (s 355). A mill that holds a risk assessment and nothing else has documented its hazards and left the zoning, the ignition-source controls, the housekeeping standard and the emergency response undocumented.
This pack closes that gap. It contains six documents: a Master SOP that governs how the pack is implemented and kept current; a Fire & Explosion Risk Assessment that walks every process unit of the mill — receival, elevators, hammer mill, mixing and liquid addition, pellet press, cooler, dryer, dust collection, bins and silos, conveying and bagging, electrical, hot work, combustible liquids, vehicles and management of change — scored on the house 5 × 5 method with hierarchy-tagged controls and routing to permits, plans and SWMS; a Hazardous Area Classification & Dust Zoning Register for Zone 20/21/22; an Ignition Source Control Register with the hot-work permit interface that s 355 depends on; a Dust Accumulation Inspection & Housekeeping Regime with layer-depth action limits, because the secondary explosion is what destroys a building; and a Fire & Explosion Emergency Response Annex with the mill-specific procedures for smouldering product, collector fires and explosions, and the dated fire-equipment test record s 359(1)(d) requires. Every regulatory citation was checked against the consolidated text of the Regulation before authoring.
The practical problem for most mills is not knowing that these duties exist — it is getting anyone qualified to help. Occupational hygienists and process-safety specialists with combustible-dust experience are scarce, regional NSW is served last, and a wait of six months or more for a site visit is common. A mill cannot leave its elevators and collectors unassessed for that long, and a regulator will not accept a booking confirmation as a control. This pack lets the mill start now: walk the plant, classify the zones, control the ignition sources, set the housekeeping standard and put the emergency procedures in place this month, with every document mapped to the section of the Regulation it discharges. When a specialist is engaged, they arrive to a mill that has done the groundwork — the hazard register, the zoning judgements and the data gaps are already on paper — which shortens the engagement and lowers its cost.
- ✗The Zone 20/21/22 hazardous area classification
- ✗The ignition source register and hot-work permit interface
- ✗The measured dust-accumulation housekeeping standard
- ✗The emergency procedures and the s 359 fire-equipment test record
Sections 51 to 53, 355, 359 and 43 of the WHS Regulation 2025 (NSW) each carry a separate duty. This pack is what documents them — and it is the groundwork a specialist would otherwise spend their first days on site producing.
The 6 documents, in detail
Every document is authored for NSW, supplied as an editable, unbranded Microsoft Word file, and ready to complete for your specific assets. No blind purchase — here is exactly what you receive.
Master SOP
Combustible Dust Fire & Explosion Management: the governing procedure for the whole pack — roles and competence, first-time implementation step by step, how each document is completed and kept consistent, a daily-to-three-yearly compliance calendar, the permit-to-work interface, interlock and bypass control, impairment of fire and explosion protection, management of change, contractors and visitors, warning signs, incidents and restart, training, audit and records. Appendices: go-live readiness checklist, management of change form, contractor and visitor induction checklist, annual review checklist and a stop-and-report card.
Fire & Explosion Risk Assessment — Animal Feed Mill
73 pre-identified hazards across the whole mill, with a start-here guide for leading the assessment, the hazard in plain English, key terms, indicative dust characteristics and a conservative design baseline, step-by-step risk scoring, a walk-through guide of what to look for, routing to permits, plans and SWMS, a controls verification checklist, action plan, roles, consultation, review and sign-off.
Hazardous Area Classification & Dust Zoning Register
Zone 20/21/22 definitions, classification inputs, a zoning register with typical zone extents for each area and item of plant, an equipment-in-classified-areas verification log and competent-person sign-off.
Ignition Source Control Register
the ignition sources of a feed mill and their controls, a register with verification methods and frequencies — bearings, magnets, hammers and screens, sensors, suppression, permits and burners — the hot-work permit interface and portable-equipment rules.

10 hazards, identified and controlled
These are the hazards the documents are built around — each with the consequence that makes it matter, rated by priority. This is the depth a regulator expects and a generic template does not carry.
Belt slip, misalignment or a seized bearing ignites the continuous dust cloud in the casing — the most common initiation point for mill explosions; propagation to bins and the building.
A pressure wave from any primary event lofts settled dust on beams, ledges, ducts and roof spaces into a cloud that the flame front ignites — the building-wide event that kills people away from the origin.
Concentrated fines ignited by a carried spark, static from filter media or an ember; propagation back through ducting into the plant if not isolated.
Sparks or hot spots in the finest dust on site; explosion in the mill and its aspiration system.
Self-heating meal or hot pellets smoulder in storage; opening, disturbing or watering the vessel turns a nest into a cloud fire or explosion; entrapment during entry.
Welding, cutting or grinding without shutdown, cleaning, isolation and fire watch — direct ignition of a dust cloud or layer.
Dust ingress, hot enclosures, damaged luminaires or portable tools ignite a cloud or a layer resting on a hot surface.
Die friction, blocked dies, product build-up on hot surfaces and burner faults start fires that spread to the cooler and storage.
Fats, oils, molasses, diesel and LPG add a pool or jet fire load that can escalate to the process building.
A new fine ingredient, higher throughput, relocated collector or bypassed interlock changes the dust or the zone extent without the controls being reconsidered.
Where holding only a SWMS goes wrong
A regional mill receives wheat, barley and canola meal by truck, grinds through a single hammer mill into a batch mixer with liquid fat addition, and pellets through one press with a counterflow cooler into four finished-feed bins and a bagging line. On the first walk with Document 01 the team scores the elevator legs, the hammer mill and the collector at Extreme inherent risk, which is where the pack expects them to be. Document 02 classifies the inside of every leg, the mill housing, the collector and the bins during filling as Zone 20, the tip station and bag-change area as Zone 21, and the process floor as Zone 22 on the condition that housekeeping is held to the Document 04 standard. Document 03 then surfaces the gap: the elevator bearing sensors are fitted but wired to an alarm only, not a shutdown, and there is no hot-work permit — the last contractor welded a bracket on the mill leg with the plant running. Both go on the Document 01 action plan with owners and dates. The first Document 04 round finds dust footprints on the elevator tower floor — a Stop finding traced to a split boot seal, which is repaired the same week. Document 05 is inserted into the site emergency plan; the fire brigade is briefed on the bin layout and told that a smouldering bin is never to be opened or jetted. The residual profile after closure is High on the confined dusty plant and Medium elsewhere — which is what the pack says a well-run mill should expect.
High risk construction work under s291
Why this work is high risk construction work, category by category — and what the law requires once it is.
Work in or near a confined space
Entry into bins, silos, hoppers, coolers and dust collectors for cleaning, inspection or repair. The risk assessment routes these rows to a confined-space entry permit and a SWMS.
Work in an area that may have a contaminated or flammable atmosphere
Maintenance and construction work inside classified Zone 20/21/22 areas — hot work on elevators, mills, collectors and bins. Routed to the hot-work permit and a SWMS.
Work on or near energised electrical installations or services
Work on explosion-protected electrical installations in classified areas during fault-finding, replacement or inspection.
Where the work is construction work — installation, repair, maintenance or alteration of the mill's plant and structure — the high risk construction work categories above require a Safe Work Method Statement under s 291 and s 299 of the WHS Regulation 2025 (NSW) before the work starts. The routing column of the risk assessment identifies which rows trigger that duty. The fire and explosion duties in ss 51–53 and s 355 apply to the operating mill whether or not construction work is taking place.
The NSW codes of practice listed are approved under s 274 of the WHS Act 2011 (NSW) and are admissible in proceedings as evidence of what is known about a hazard and how to manage it. The Australian and international standards are cited as the recognised technical basis for zoning, equipment selection, static control, hot work and fire-equipment servicing; they are not themselves law in NSW.
