It is sometimes necessary in bridge and highway repair, to remove small amounts of concrete. Compact pneumatic chipping hammers (jackhammers) are often used to do the job. These compact battering rams pack a lot of punch, and they can be dangerous if not used properly. Here are some common-sense tips provided by tool manufacturers.
Dress Appropriately to Protect Yourself
- Everyone in the area should always wear impact-resistant eye protection.
- Depending on the situation, wear a facemask or respirator.
- Wear a hardhat, especially if there is a risk from falling objects.
- Wear adequate clothing that fits properly.
- Wear proper hearing protection.
- Wear gloves to protect your hands and steel-tipped boots to protect your feet.
- Set up screens to prevent nearby workers from being struck by flying fragments.
Inspect the Jackhammer and Tools Before Use
- Carefully inspect the jackhammer for damage and make sure all controls and safety interlocks work properly.
- Inspect air hose connections at the air compressor and the jackhammer for cracks, worn threads and loose couplings.
- Inspect the safety clip or tool retainer for proper operation. This prevents the chisel/tool from being unintentionally shot from the barrel.
- Check the chisel/tool for tightness of fit and excessive wear. Repair or replace when required, following the manufacturer’s recommendations.
Beware of Air Under Pressure
- Never engage in horseplay with compressed air – it’s dangerous!
- Always disconnect the tool when it is not in use or when you are changing accessories.
- Never exceed the tool’s designated operating pressure.
Proceed With Caution
- Always keep both hands on the tool.
- Watch for excess lengths of the air hose, which can cause you to trip.
- Never operate the tool without the chisel against the work surface.
- Discontinue use if numbness, tingling, pain, or flushing of the skin occurs.
- Prevent back injuries by using your leg muscles to lift the jackhammer into position.
- Allow the tool to do the work by using a grip light enough to maintain control.
- Always follow any special manufacturer instructions.
Work smart and work safe when using jackhammers or any other equipment on the jobsite.
