Subcontractor Responsibilities


If you’re a subbie who is only on-site for a couple of hours, you still have health and safety responsibilities. From workers through to company directors, safety on-site is now everyone’s responsibility.

Here’s an example: Sam is a self-employed floor sander. He often does sanding on residential renovations for his friend the builder, Bruce. Although Sam may only come on-site for a few hours or days, he is still a PCBU (person conducting a business or undertaking) and has responsibilities. The extent of his duty will depend on how far he is able to control the risk. The more influence and control he has over the risk, the more responsibility he has. And because Sam is usually sharing a site with other crews or workers, he needs to be consulting with these other businesses to make sure everyone on-site is kept safe.

Under the recent Health and Safety at Work Act, clients, principals, main contractors and sub-contractors are all PCBUs. Despite the name, a PCBU is not necessarily one person – in most cases a PCBU will be a business entity, like a company or organisation but it could also be an individual running their own business, like a sole trader. A PCBU has the “primary responsibility of care” to ensure the safety of its workers and anyone affected by its work.

PCBUs must (as far as is reasonably practical):

  • Have a safe site, plant, structures and ways of working
  • Make sure plant, structures and substances are used, handled and stored safely
  • Provide facilities for the welfare of workers, such as running water and toilets
  • Provide the necessary information, training and supervision to protect people from risk
  • Monitor health and workplace conditions

As Sam is self-employed, he is also classed as a “worker” under the Act. This means he also has a responsibility to take reasonable care to ensure the health and safety of himself and others in the workplace.

So, what should I be doing?

Let’s take Sam. He may only be on-site for a day but he still needs to be thinking about what risks there might be and what he can do to manage them. As a minimum, we would suggest Sam:

  • Meets with the main contractor before starting work to discuss the job, any risks and what to do in an emergency.
  • Completes a Site Specific Health and Safety Agreement with the main contractor, a Hazardous Products and Substances Register for his varnishes and stains, and a Site/Job Hazard Risk Register. The Hazardous Products and Substances Register may be the same for most of his jobs and might just need minor changes for each job.
  • Does a quick Step Back 5x5 to think through the job. A Step Back 5x5 is when you step back five paces from the job and spend five minutes planning. Ask yourself: 
  • What will I be doing?
  • What are the hazards?
  • What equipment and plant do I need?
  • How can I get hurt?
  • What if something unexpected happens?

This is just an example of one scenario - it is important to remember that each job is different and will require a different approach depending on the circumstances.

Not just ticking the boxes

By talking to the main contractor and completing the Agreement, Sam is helping to communicate what he is doing about safety. By completing the Hazardous Products and Substances Register and Site/Job Hazard Risk Register, he is communicating what the risks of his work might be and how he will manage them on-site. By completing the right safety documentation, he is not just “ticking the boxes” but taking a systematic approach to managing risks. This reduces the chances of miscommunication and mistakes. In the event of an accident or injury, it is also evidence that Sam is on top of safety.

In a nutshell, the job is not there to create paperwork, the paperwork is there to support the job.
