NSW silo and bin safety: better design before a dangerous task arises
A grain silo can look quiet while concealing serious hazards. Stored material can move unexpectedly, machinery can entangle a person, and an apparently empty space can contain a dangerous atmosphere. Familiarity with the farm does not make those hazards disappear.
The NSW Safe use and design of bulk storage silos and bins code commenced on 22 May 2026. It replaced the 2005 design code and the 2006 safe-use code. Its scope is agricultural bulk storage silos and bins, including storage of unpackaged grain, fertiliser and stock feed. Large horizontal storage such as bunkers and sheds is outside its scope.
Start before purchasing or changing equipment
A safer system begins with selecting equipment suited to the product, location and intended work. Different stored materials have different properties. A container suitable for one commodity is not automatically suitable for another.
Ask the designer or supplier how workers will inspect, sample, clean and maintain the equipment without unnecessary climbing or entry. Ground-level controls and external inspection arrangements can remove a dangerous task rather than merely make it easier to perform.
Location matters too. Vehicle movements, foundations, electricity infrastructure, nearby work areas and unauthorised access need consideration. Alterations should be assessed with the manufacturer, supplier or appropriately qualified engineer; a seemingly minor change can affect structural safety and bring design responsibilities.
Treat blockages and maintenance as planned work
A blockage creates pressure to restart production. That is precisely when an improvised response can become dangerous.
Grain may bridge over a hidden void or adhere to a wall before collapsing. Moving material can engulf a person. Never walk on bridged or crusted grain. Do not enter a silo or bin to investigate or clear a problem without competent assessment and the required safe system of work.
The code addresses confined-space assessment, entry permits, isolation, communication, monitoring and rescue arrangements. These are connected safeguards, not a menu from which to select one or two. A short article cannot provide a safe entry, clearing or rescue procedure.
Maintenance and inspection must be undertaken by competent people at the appropriate intervals. Keep useful records of inspections, defects, repairs and modifications so the next person is not relying on memory.
Look beyond the most obvious hazard
The code also covers structural collapse, falls, fire and explosion, electricity, airborne contaminants, noise, fatigue and psychosocial risks. Dust can create both respiratory and explosion hazards. An atmosphere cannot be declared safe because nothing unusual can be seen or smelled.
Protective equipment and a gas monitor do not replace effective hazard controls. Fumigation and other chemical work require competent advice about current product, licensing and workplace requirements, not a generic instruction from a blog.
Seasonal workload and isolated work deserve attention alongside machinery. Workers need understandable instructions, appropriate supervision and a practical way to raise concerns. Consultation should include relevant health and safety representatives and coordination with contractors and other businesses.
Plan for people who are not doing the job
A farm may also be a home. Children, visitors and delivery drivers need protection from operational areas, machinery and chemicals. Secure access and clear arrangements matter more than assuming everyone knows where not to go.
Emergency planning should match the actual location and hazards, including the availability of help. Do not enter a silo or bin in an improvised rescue or attempt to fight a silo fire yourself. Call 000 in an emergency and keep others clear while trained responders take control.
Current law and the official code
Read the code with the WHS Regulation 2025 and current applicable requirements. SafeWork NSW confirms that WHS Act section 26A commenced on 1 July 2026: duty holders must comply with an applicable approved code or manage the hazard through an equivalent or higher standard of work health and safety.
