A safety blitz by Work Safe Victoria has found the state's construction industry riddled with safety shortfalls, with the watchdog finding 90 breaches across the sector in the last month in Western Victoria alone.

WorkSafe inspectors visited almost 120 housing construction sites in and around Bendigo, Ballarat, Mildura, Warrnambool and Geelong as part of Operation SafeSite - a 12-month campaign aimed at reducing workplace injuries in the industry.

WorkSafe Chief Executive, Denise Cosgrove, said site safety was the responsibility of everyone on site including the builder, contractors and workers.

“It was pleasing to see some sites had heeded warnings about the blitz and made sure safety was up to scratch before inspectors arrived,” she said.

Inspectors issued 51 improvement notices requiring businesses fix health and safety breaches.  Another 39 breaches were identified, but were able to be dealt with on the spot.

Ms Cosgrove said there were simple steps that can be taken to make a real difference to site safety.

“Having the site fenced, kept clean of building rubble and waste and ensuring electrical tools are safe are just some of the simple steps that can make a real difference to workers and public safety.

“The risks on housing sites are well known and so are the control measures. Safety doesn’t just happen - it requires planning, having effective controls in place and regular supervision to ensure the site remains safe.”
