Hydraulic breaker attachments fitted to excavators are used to break concrete, rock, and hard ground on construction sites. The forces involved are extreme, and flying debris, noise, vibration, and dust create multiple hazards for both the operator and nearby workers. This talk covers the safe operation of excavator-mounted breaker attachments and the exclusion zone requirements that protect everyone on site.
Key Hazards
Flying debris striking workers near the breaker during concrete breaking operations
Excessive noise exposure causing hearing damage to operator and nearby personnel
Whole-body vibration transmitted to the excavator operator during sustained breaking
Dust and silica exposure from breaking concrete without adequate suppression controls
Control Measures
Establish an exclusion zone around the breaker work area to keep all non-essential personnel clear.
Ensure the excavator operator holds a current CPCS card with the breaker attachment endorsement.
Check the breaker, mounting pins, hoses, and quick hitch connection before each shift.
Use water suppression to control dust when breaking concrete or materials containing silica.
Wear hearing protection within the designated noise zone around the operating breaker.
Do not use the breaker in a prying or levering action — operate vertically as the manufacturer intends.
Rotate operators to limit whole-body vibration exposure within the daily action value.
Ensure underground services have been located and marked before breaking ground in any area.
Brief nearby workers on the exclusion zone and expected noise and dust levels before starting.
Remember
Establish an exclusion zone around the breaker area to keep non-essential personnel clear
Check the breaker, mounting pins, hoses, and quick hitch connection before every shift
Use water suppression when breaking concrete to control silica dust at the source
Wear hearing protection within the noise zone and rotate operators to manage vibration exposure
Operate the breaker vertically as designed — never use it in a prying or levering action
Locate and mark underground services before breaking ground in any new work area
