WorkSafe VIC - Mobile Boom Pump Safety
Following numerous incidents involving boom pumps placing workers and the public at risk, WorkSafe inspectors are currently visiting construction sites to ensure the risks associated with setting up and operating truck-mounted mobile concrete boom pumps (boom pumps) are being controlled.

Incidents have included:
Overturning boom pumps due to situations such as structural slab failure, ground conditions and short blocking outriggers
Structural failure in the boom or slew ring
Full or partial collapse of the boom
End hoses uncoupling and falling during the pout or while being cleaned out
End hoses whipping around
Concrete or the pipe clean-out device ('sponge') striking people during the clean-out process
Bursting pipes, bends and end hoses
Pipe clamp failures
People being entangled in the pump's moving parts
Boom striking overhead powerlines
WorkSafe VIC August/September Focus
WorkSafe inspectors will ensure duty holders involved in concrete pumping operations are complying with their obligations, which include (but are not limited to):
Providing and maintaining plant or systems of work
Boom pump operators hold a high-risk work licence (ie ‘Class PB – concrete-placing boom’)
Safe work method statement (SWMS) is prepared before high-risk construction work commences and work is performed in accordance with the SWMS
Risks associated with concrete pumping operations are controlled and the Concrete pumping industry standard is followed, including requirements related to:
The location of the boom pump set-up;
Public areas set-up, including traffic and pedestrian controls
No-go zones for overhead powerlines (see image)
Boom pump inspections and maintenance, including pipe componentry (eg pipe clamps and safety pins)
Thickness testing for pipeline components
Boom pump set-up, including outrigger placement
Control of trucks discharging into the hopper
Hopper guarding and emergency controls
Pump and pipeline clean-out process.
