Safely immobilising heavy vehicles and trailers


Between 2012 and 2016, there were 23 fatalities and other incidents in Queensland where a worker was crushed or hit by a heavy vehicle or trailer because it was not immobilised correctly.

Since then, there have been a number of incidents where heavy vehicles have unexpectedly moved causing injury and/or significant property damage, as well as a number of near misses. Many of these incidents could have been prevented by applying the braking system.

During 2017, Workplace Health and Safety Queensland (WHSQ) inspectors visited hundreds of workplaces across Queensland, providing practical guidance on managing the risks around immobilising trucks and trailers.

Businesses need to ensure that vehicles and trailers are safely immobilised, especially when workers get out of, are near, under or on the truck or trailer.

Commencing in February 2018, WHSQ will be contacting workplaces to arrange a compliance assessment on their systems of work for immobilisation of heavy vehicles and trailers. Inspectors will be taking the appropriate enforcement action, including issuing notices where risks are not being effectively managed.

Businesses can use the resources below to help ensure a safe system of work.
