Handheld breakers and demolition hammers are used to break out concrete, tarmac, and masonry on construction sites. They generate high levels of noise, vibration, and dust, and the physical demands of operating them can cause serious musculoskeletal and hand-arm vibration injuries. This talk covers the safe use of breakers and demolition hammers, the exposure limits, and the controls needed to protect operators.
Key Hazards
Hand-arm vibration syndrome from prolonged breaker use exceeding exposure limits
Hearing damage from sustained high noise levels during breaking operations
Silica dust inhalation when breaking concrete without dust suppression controls
Musculoskeletal injuries from the weight and physical demands of operating breakers
Control Measures
Check the vibration magnitude of the tool and calculate the maximum daily exposure time permitted.
Rotate operators regularly to keep individual vibration exposure below the daily action value.
Use water suppression or dust extraction to control silica dust at the point of breaking.
Wear hearing protection rated for the noise level of the specific breaker being used.
Inspect the breaker, chisel, and hoses before each use for damage, wear, or loose connections.
Ensure the correct chisel type is fitted for the material being broken — point, flat, or spade.
Take regular breaks to allow blood circulation to recover in the hands and fingers.
Wear anti-vibration gloves and ensure a firm but not excessively tight grip on the handles.
Report any tingling, numbness, or whitening of fingers to your supervisor immediately.
Remember
Calculate the maximum daily exposure time based on the tool's vibration magnitude before use
Rotate operators regularly to keep individual vibration exposure below the daily action value
Use water suppression or dust extraction to control silica dust when breaking concrete
Wear hearing protection rated for the specific noise level of the breaker being operated
Take regular breaks and report any tingling, numbness, or whitening of fingers immediately
Inspect the breaker, chisel, and hoses for damage before every use on site
