Manufacturing WHS Management System

A compliant manufacturing WHS management system must address the full range of hazards present across production, maintenance, storage, and dispatch operations. The foundation is a current WHS policy endorsed by senior management, supported by hazard identification and risk assessment procedures that cover every machine, process, and material in use. Safe Work Method Statements are required for all high-risk work including confined space entry, hot work, and work at height. A chemical register must list every raw material, process chemical, cleaning agent, and maintenance product with current Safety Data Sheets accessible to all workers. Workplace exposure monitoring programs must be established for every substance with a workplace exposure limit that is relevant to the facility's processes. Lockout tagout programs must cover every machine and energy source that could endanger workers during cleaning, maintenance, and changeover. Machine guarding programs must ensure all presses, lathes, conveyors, mixers, and other plant meet the requirements of the Managing Risks of Plant Code of Practice. Noise management programs with audiometric testing are required where workers are exposed above 85 dB(A). Manual handling risk assessments, emergency planning, forklift management, and contractor management round out the core components. EHS Atlas integrates all of these elements with automated reminders, audit scheduling, and regulator-ready documentation.

The WHS Regulation 2025, which commenced on 1 September 2025, introduced several changes directly relevant to manufacturing operations. Psychosocial hazards are now explicitly regulated under Regulation 55C, requiring PCBUs to identify and control risks from excessive workload, shift work fatigue, workplace bullying, poor organisational justice, and exposure to traumatic events. Manufacturing environments with sustained production pressure, rotating shift patterns, and repetitive tasks must now formally assess and control these psychosocial risks alongside traditional physical and chemical hazards. The regulation strengthens requirements around health monitoring for workers exposed to hazardous chemicals, including mandatory medical examinations and biological monitoring for workers with regular exposure to scheduled substances. Air monitoring obligations have been clarified to require personal sampling where workers are exposed to substances with workplace exposure limits. Machine guarding requirements have been reinforced with specific obligations around isolation and lockout procedures, and the duty to ensure that guarding is maintained in effective working order is now supported by enhanced penalty provisions. The regulation also introduces lithium-ion battery storage and charging requirements relevant to manufacturing facilities that use battery-powered equipment and vehicles.

From 1 July 2026, Section 26A of the WHS Act transforms approved codes of practice from guidance into legally binding instruments. For manufacturing businesses, the codes that become binding include Managing Risks of Hazardous Chemicals in the Workplace, Managing Noise and Preventing Hearing Loss at Work, Confined Spaces, Hazardous Manual Tasks, Managing Risks of Plant in the Workplace, Managing the Risk of Falls at Workplaces, Spray Painting and Powder Coating, and Managing Electrical Risks in the Workplace. Under the current framework, a manufacturer can comply by following a code or by adopting an alternative measure that achieves an equivalent standard. After Section 26A commences, failure to follow a binding code will be a standalone offence unless the PCBU proves that an alternative measure provides equal or greater protection. This is particularly significant for manufacturing because the Managing Risks of Plant Code of Practice sets detailed requirements for machine guarding, isolation, and maintenance that many facilities have historically met through informal practices rather than documented procedures. Manufacturing businesses should audit their current procedures against each applicable code now and update SWMS, standard operating procedures, and training materials before the July 2026 commencement date.

The December 2026 workplace exposure limit transition will impact manufacturing across multiple substance categories. Styrene drops from 50 to 20 ppm — a 60 per cent reduction affecting plastics, fibreglass, and rubber manufacturing. Isocyanates tighten from 0.02 to 0.005 mg/m³ — a 75 per cent reduction affecting foam manufacturing, spray painting, and polyurethane processing. Formaldehyde reduces from 1 to 0.3 ppm — a 70 per cent reduction affecting resin manufacturing, plywood production, and textile finishing. Wood dust falls from 1 to 0.5 mg/m³ — a 50 per cent reduction affecting furniture manufacturing, joinery, and timber product operations. Manganese drops from 1 to 0.02 mg/m³ — a 98 per cent reduction affecting any manufacturing process that involves welding carbon steel components. The breadth of these changes means that most manufacturing businesses will face compliance challenges across multiple substances simultaneously. Prioritisation based on baseline exposure monitoring is essential. Facilities should identify which substances exceed the incoming WELs, rank them by the margin of exceedance, and implement controls in priority order. EHS Atlas tracks every substance against the incoming WEL and flags exceedances automatically.

Since 10 June 2020, WHS penalties in Australia have been uninsurable — no insurance policy can indemnify a business or officer against a fine imposed under the WHS Act. Every dollar of every penalty comes directly from the business or the individual. Category 2 offences carry maximum penalties of $1,731,500 for a body corporate and $346,300 for an individual. Industrial manslaughter carries a maximum fine of $20 million for a body corporate and 25 years imprisonment for an individual. The current penalty unit is $123.31. Recent prosecutions in manufacturing demonstrate active enforcement. Orica Australia Pty Ltd was fined $1.2 million in 2024 after workers were exposed to cobalt dust without adequate ventilation or health monitoring, resulting in occupational lung disease. SafeWork SA prosecuted a manufacturer resulting in an $840,000 penalty in 2024 following an apprentice death caused by inadequate machine guarding and supervision during maintenance operations. These cases demonstrate that regulators pursue maximum penalties when machine guarding, chemical exposure controls, and supervision failures result in worker harm. A properly implemented WHS management system with robust machine guarding, lockout tagout procedures, and chemical exposure controls is the most cost-effective protection against prosecution in manufacturing.
