Health and Safety for Trade Businesses

Who holds the duty

Australian WHS law puts the primary duty on the person conducting a business or undertaking — the PCBU. That's the business, and in a small trade business it's effectively you. The duty is to ensure, so far as is reasonably practicable, the health and safety of workers and of anyone else affected by the work.

Two parts of that are worth reading twice. Workers is broader than employees — it takes in subcontractors, labour hire, apprentices and volunteers. And anyone else affected covers the client, the neighbour, the kid on the footpath. You don't get to scope the duty down to the people on your payroll.

There's a second duty on top if you're a company director or hold a senior decision-making role: a positive duty of due diligence — to actually know what the hazards are, to make sure there are resources and processes to deal with them, and to check they're being used. It can't be delegated away to a supervisor.

How the rules fit together

There's no single national WHS law. Safe Work Australia develops model laws and model codes of practice, but it doesn't regulate anyone — each state and territory decides what to adopt and enforces its own version. That's why the framework looks the same everywhere and the detail doesn't.

• The Act — the broad duties. Who owes what to whom, and the consequences.
• The Regulations — the specifics. Particular hazards, particular work, thresholds, licences and notification requirements.
• Codes of practice — practical guidance on how to meet the duties. Not optional reading: they're admissible in proceedings as evidence of what was reasonably practicable.
• The regulator — the agency that inspects, advises and enforces in your jurisdiction. Most states also have a separate workers compensation authority.

Most jurisdictions have adopted the model WHS laws, with Victoria running its own long-standing occupational health and safety framework instead. The practical differences show up in thresholds, notification timeframes and licence categories rather than in the underlying duty. Find your regulator's website, bookmark the codes of practice that apply to your trade, and work from those rather than from a summary.

What you're actually required to do

Stripped of the legal wording, the duty resolves into a list a business owner can act on:

• Provide and maintain a safe work environment and safe systems of work.
• Provide and maintain safe plant and structures — including the ute, the ladders and the leads.
• Ensure the safe use, handling and storage of plant, structures and substances.
• Provide adequate facilities — water, toilets, somewhere to eat, appropriate to the site.
• Provide the information, training, instruction and supervision needed to do the work safely.
• Consult your workers on matters that affect their health and safety, and consult other businesses you share a site with.
• Monitor conditions and the health of workers where the work requires it.
• Have arrangements for emergencies and first aid.

Consultation is the one small businesses most often skip, and it's a standalone duty rather than good manners. It doesn't require a committee — a genuine conversation with the crew about a hazard, and a record that you had it, is consultation.

Building a system a small business can actually run

Big-company safety systems fail in small trade businesses because nobody has time to feed them. Build the smallest thing that's real, then keep it current:

1. Write down your hazards. Go through the work you actually do and list what could hurt someone: heights, electricity, silica and other dusts, asbestos in older buildings, manual handling, plant and vehicles, chemicals, noise, heat and sun, and fatigue. Trade-specific, not generic.
2. Decide the controls, top-down. For each hazard, work down the hierarchy — eliminate, substitute, isolate, engineer, then administrative controls and PPE last. Write the control you'll actually use, not the one that sounds best.
3. Put it into the job. A control that lives in a policy folder doesn't exist. It has to show up as a step in how a job gets set up, quoted and resourced — the second person for the lift, the scaffold instead of the ladder, the time allowance for isolation.
4. Do the paperwork the work requires. SWMS for high-risk construction work, and a task-level assessment for everything else worth thinking through. Keep them job-specific.
5. Train and induct. White cards, tickets for high-risk work, and a real site induction for each new site. Record who was trained in what and when.
6. Review after anything goes wrong. Every incident and near miss gets looked at, and the control changes if it needs to. A near miss investigated properly is the cheapest safety improvement you'll ever get.

The hazards that dominate by trade

Every trade has its own short list of things that cause most of the harm. Start your risk register with yours:

Two of those deserve separate attention because the consequence is fatal and delayed: asbestos in anything built before the ban, and respirable crystalline silica from cutting engineered stone, concrete, brick and tile. Both are heavily regulated, both have specific codes of practice, and both are managed with elimination and engineering controls rather than a dust mask.

The business case, briefly

The reason to do this is that people get hurt otherwise. But a safety system that's actually written down also does three things for the business, and they're worth naming:

• It wins commercial work. Head contractors and government clients ask for your safety documentation at prequalification. No documents, no tender.
• It keeps good people. Nobody stays long at a business that treats safety as an inconvenience, and the ones who leave first are the ones you least want to lose.
• It lowers your cost of risk. Fewer claims, less downtime, and a much better position with your insurer and your workers compensation authority when something does happen.
