Executive Summary
This report presents the findings of a work health and safety audit of a medium-sized food-processing facility located in South East Queensland. The facility employs approximately 180 workers across chilled processing, packaging, sanitation and dispatch functions and operates two shifts. The audit was commissioned to assess compliance with the Work Health and Safety Act 2011 (Qld) and associated Regulation, to benchmark practice against the international standard for occupational health and safety management systems, and to identify priority risks.
The audit found a functioning safety system with genuine strengths, including active senior management commitment, a documented incident-reporting process and a well-maintained ammonia refrigeration permit regime. It also identified significant gaps. Machine guarding on two legacy lines was incomplete, sanitation chemical controls were inconsistently applied, and manual handling risks in the packing area were not adequately controlled. Nine findings were rated, of which two were high risk, four were moderate and three were low. A prioritised action plan is recommended, beginning with the isolation and guarding deficiencies that expose workers to the most serious harm.
Background
Food processing is a hazardous industry. National regulator data consistently place manufacturing, which includes food product manufacturing, among the sectors with higher rates of serious workers’ compensation claims, driven by machinery, manual handling and slips on wet surfaces (Safe Work Australia 2022). The facility subject to this audit combines several of these hazards in a single environment: powered conveyors and slicing equipment, sharp hand tools, wet and refrigerated floors, caustic sanitation chemicals, forklift movement in shared areas, and an anhydrous ammonia refrigeration plant.
In Queensland the primary duty of care rests with the person conducting a business or undertaking under the Work Health and Safety Act 2011 (Qld), which mirrors the model laws developed by Safe Work Australia and is regulated by Workplace Health and Safety Queensland (Queensland Government 2011). The duty requires that risks to health and safety be eliminated so far as is reasonably practicable, and where elimination is not possible, minimised. Electrical safety is separately governed by the Electrical Safety Act 2002 (Qld). The audit assessed the facility against these obligations and against the management-system requirements of the international standard for occupational health and safety, which is structured around leadership, planning, operation, and performance evaluation (Standards Australia 2018).
Methodology and Approach
The audit was conducted over three days and used a triangulated method combining document review, physical inspection and worker interviews. The approach followed a plan, do, check, act logic consistent with recognised management-system auditing practice.
- Document review. Safety policy, the risk register, safe work method statements, plant maintenance records, chemical safety data sheets, training records, and 18 months of incident reports were examined for currency and completeness.
- Physical inspection. A structured walkthrough of processing, sanitation, cold storage, dispatch and plant rooms was completed using a checklist derived from the relevant codes of practice. Observations were photographed where permitted and recorded against the hierarchy of controls.
- Worker and supervisor interviews. Fourteen workers and four supervisors were interviewed to test whether documented controls were understood and applied in practice, and to surface concerns not captured in formal records.
Each identified hazard was assigned a risk rating using a five-by-five likelihood and consequence matrix, producing an overall rating of low, moderate or high. Findings were then mapped to the specific legislative or standard obligation they engaged, so that remediation could be prioritised by both severity and legal exposure.
Findings
Machine guarding and isolation
Two older packing lines had guarding that did not fully enclose in-running nip points, and the lockout and tagout procedure for these lines was documented but inconsistently followed during the observed sanitation shift. Interviews confirmed that cleaners occasionally reached into partially guarded areas while equipment remained energised. This is a high-risk finding because it exposes workers to amputation and entanglement hazards and engages the plant and machinery duties under the Regulation.
Hazardous chemicals and sanitation
The sanitation programme relies on caustic and acidic cleaning agents. Safety data sheets were available, but decanting practices were inconsistent, some secondary containers were unlabelled, and eyewash stations in one wash-down bay were partially obstructed. Personal protective equipment was provided but not always worn correctly. This was rated moderate to high, engaging the hazardous chemicals provisions and the requirement to provide adequate facilities.
Manual handling in packing and dispatch
Repetitive lifting of finished cartons and frequent awkward postures at the packing bench were observed. The existing risk assessment predated a recent line reconfiguration and no longer reflected actual task demands. Musculoskeletal complaints featured in the incident log. This was rated moderate.
Slips, trips and cold environments
Wet floors, hose management and the transition between chilled and ambient areas created slip hazards, partly mitigated by anti-slip footwear and drainage. Controls were reasonable but housekeeping was variable between shifts. This was rated moderate.
Ammonia refrigeration and emergency preparedness
The anhydrous ammonia plant was well managed, with a current maintenance regime, restricted access, gas detection and a documented emergency response. Minor gaps were noted in the currency of some evacuation drill records. This was rated low, reflecting an area of relative strength.
Forklift and pedestrian interaction
Forklifts operated in dispatch areas shared with pedestrians. Marked walkways existed but were faded in places, and one blind corner lacked a convex mirror. This was rated moderate.
Electrical safety and noise
Electrical risk in the wash-down zones was generally well controlled through residual current devices and a testing and tagging regime, although a small number of flexible leads in the sanitation area showed wear and were scheduled for replacement. This was rated low, but it engages the distinct duties imposed by the Electrical Safety Act 2002 (Qld), which applies in Queensland alongside the general work health and safety framework. Noise in the main processing hall approached the exposure standard near certain equipment. Hearing protection was provided and audiometric testing was in place, so the residual risk was rated low, although periodic noise monitoring should continue as plant ages and as production volumes change.
Table 1 summarises the rated findings.
| Finding | Primary hazard | Risk rating | Key obligation engaged |
|---|---|---|---|
| Machine guarding and isolation | Entanglement, amputation | High | Plant and machinery, energy isolation |
| Hazardous chemicals and sanitation | Burns, eye injury | High | Hazardous chemicals, facilities |
| Manual handling | Musculoskeletal injury | Moderate | Hazardous manual tasks |
| Slips, trips and cold | Falls on the same level | Moderate | General duty, housekeeping |
| Forklift and pedestrian | Impact, crushing | Moderate | Powered mobile plant, traffic management |
| Electrical wash-down zones | Electric shock | Low | Electrical Safety Act 2002 (Qld) |
| Noise in processing hall | Hearing loss | Low | Noise exposure standard |
| Ammonia refrigeration | Toxic release | Low | Major hazard controls, emergency plan |
| Emergency drill currency | Delayed evacuation | Low | Emergency plan requirements |
Analysis
The findings show a facility whose formal safety system is sound but whose implementation is uneven across shifts and functions. The most serious exposures cluster where high-energy plant meets the sanitation task, which is a recognised danger zone in food manufacturing because cleaning frequently requires access to areas that are guarded during production (Workplace Health and Safety Queensland 2020). The guarding and isolation gap is significant not only because of the severity of potential harm but because the control failure sits at the top of the hierarchy of controls; a robust isolation procedure that is actually followed would eliminate the hazard during cleaning rather than relying on the vigilance of individual workers.
The chemical and manual handling findings reflect a common pattern in which risk assessments lag behind operational change. The packing line reconfiguration altered task demands, but the supporting documents were not revised, so the paperwork no longer described the work being done. This gap between the documented system and actual practice is precisely what auditing is designed to expose, and it points to a need for a trigger that requires risk assessments to be reviewed whenever plant or process changes (Bahn 2013). The relative strength of ammonia management demonstrates that the facility is capable of high-quality control when a hazard is treated as critical, and the challenge is to extend that discipline to the more routine hazards that cause the majority of injuries.
The uneven performance across shifts also points to safety culture, rather than documentation, as the binding constraint. The paperwork required by the legislation was largely present, yet its translation into consistent behaviour depended on supervision that varied between the day and afternoon shifts. Mature safety systems rely on leading indicators, such as completed inspections and near-miss reports, rather than waiting for lagging indicators such as lost-time injuries to reveal problems. Extending the discipline evident in the ammonia programme to everyday hazards would mean treating verification, that is confirming that a control is actually working, as a routine supervisory task. It is also relevant that the cost of the priority remedies, principally fixed guarding and retraining, is modest relative to the severity of the harm they prevent, which speaks directly to the reasonably practicable test at the heart of the primary duty of care.
Recommendations
The following actions are recommended in order of priority.
- Immediately restrict cleaning access to the two legacy packing lines until fixed guarding is upgraded and a verified lockout and tagout procedure is retrained and audited on every sanitation shift.
- Rectify chemical controls by labelling all secondary containers, standardising decanting, clearing eyewash stations, and reinforcing correct use of personal protective equipment through supervised checks.
- Revise the manual handling risk assessment for the reconfigured packing area, introduce mechanical aids or bench redesign where reasonably practicable, and monitor musculoskeletal reports.
- Establish a formal management-of-change procedure so that any alteration to plant or process triggers review of the associated risk assessment and safe work method statement.
- Refresh traffic management by repainting walkways, installing a convex mirror at the identified blind corner, and reviewing forklift and pedestrian separation in dispatch.
- Reinstate a regular schedule of emergency evacuation drills and record participation, maintaining the existing high standard of ammonia plant management.
- Strengthen shift-to-shift consistency by adding brief documented safety handovers and periodic internal inspections between external audits.
Conclusion
The facility demonstrates a real commitment to work health and safety and manages its most catastrophic hazard, the ammonia refrigeration plant, to a high standard. The audit nonetheless identified two high-risk findings and several moderate ones that require prompt attention, principally the guarding and isolation deficiencies during sanitation and the inconsistent control of cleaning chemicals. Addressing these findings in the recommended order will reduce the most serious exposures first and bring practice into closer alignment with the obligations of the Work Health and Safety Act 2011 (Qld) and the management-system standard. Sustained improvement will depend less on additional documentation than on consistent implementation of existing controls across every shift.
