Jackhammers & Demolition Hammers

Jackhammers and demo hammers combine nearly every hazard at once: heavy lifting, vibration, extreme noise, silica dust, flying chips and buried utilities.

• Construction

Before you start

• Utilities located. Underground lines can be just under the slab.
• Bit or chisel in good shape and locked in
• Air hose connections secured with whip checks (pneumatic), or cord GFCI-protected (electric)
• Water spray or dust collection ready for silica control
• PPE: safety glasses and face shield, hearing protection, safety-toe boots with metatarsal guards, gloves, respirator if required

Operating

• Let the tool’s weight do the work. Don’t lean your body weight on it.
• Keep your feet out from under the bit, and keep a balanced stance.
• Take small “bites” near an edge instead of driving deep into the middle where the bit can get stuck.
• Lift with your legs when moving the hammer. Get help or use a cart for heavy units.
• Take regular breaks and rotate tasks to limit vibration exposure. See Hand-Arm Vibration.

• Don’t pry a stuck bit with the hammer handles.
• Don’t use a hammer that’s too heavy for the job or for you.
