WorkSafe ACT inspectors will this week start targeted checks of construction sites installing pre-cast concrete panels following recent safety incidents such as the crushing of a small toilet block and a car in Braddon in late January.
Work Safety Commissioner Greg Jones said that concrete panels created off-site are being increasingly used on ACT construction sites but their installation is a high-risk activity with potentially serious consequences if a panel collapses.
“The installation of the panels is a high-risk construction activity and unfortunately across the country, serious injuries to workers have occurred during the installation of the panels and also when temporary supports are removed,” Mr Jones said.
He said that panels have fallen on sites in the ACT in the recent past and it has been very fortunate that they did not cause serious injury.
“The collapse of any concrete panel, even a small one, can have catastrophic consequences for workers or the public,” he said.
On January 30 this year, a 3.7-tonne concrete panel fell for nearly 20 metres at a construction site at 32 Mort Street, Braddon, crushing a small toilet block and a car parked nearby.
The panel had been temporarily installed at the site of the Yamaroshi apartment complex and was in the process of permanent fixing when it became dislodged and fell. Thankfully, no one was injured.
Mr Jones said WorkSafe ACT inspectors will be checking processes on sites involving precast panel installation. This will include checking safety design aspects and any modifications, installation, the removal of temporary supports and other potential safety risks.
“Pre-cast concrete panels, which have been created off-site and installed by crane, are an increasingly common building product across both residential and commercial development,” he said.
“The risk of panel collapse exists throughout the entire construction process, not only during the panel erection phase.
“The risk of collapse must be managed until the concrete panel is effectively part of the building’s permanent structure.”
Mr Jones said that he has recently sent a safety alert to local industry reminding them of the risk and the importance of Safe Work Method Statements for such activity.
“Erecting precast concrete panels, using mobile plant around the panels and altering or removing temporary bracing is always high-risk construction work and I’ve reminded industry of this as well as advising that this activity will be a key focus over the next few months.”
