Concrete chipping operations may be on some jobsites. When required certain equipment and procedures must be followed.
Our safety training today will cover some basic safety precautions while performing chipping operations.
Eye and Face Protection- Always wear company approved eye protection and a clear face shield that attaches to the hard hat.
Head Protection- Just like any other job, all employees must wear hardhats at all times. Hardhats must be worn with the bill of the hat forward to protect your face.
Hand Protection- Because of the constant vibration produced by jackhammers or chipping guns, antivibration gloves must be worn. These special gloves are designed to reduce the impact vibration on your hands and wrists. If they are not worn, the user may feel numbness, tingling, and pain in the hand, wrist and forearm area. Additionally, the skin may become more whitish in color.
Hearing Protection- Is required if working in enclosed areas such as elevator shafts, stairways, room surrounded by walls or a basement area. If working in an open area, hearing protection will be required if concrete chipping lasts for more than one hour.
Respiratory Protection- When chipping concrete a fine dust is produced when the concrete breaks apart. If you operate a chipping gun or jackhammer for more than one hour a respirator is RECOMMENDED. However, a steady stream of water applied to point of impact between the chisel and concrete will reduce the dust created.
INSPECTION AND USE
Before using a chipping gun or jackhammer, check the tool for tightness and wear. Inspect the cord for cuts and loose plug-in prongs. If using a pneumatic jackhammer check hose connection for cracks, worn threads, loose couplings and be sure short safety chain is connected between the air-to-tool connection.
Never engage in horseplay with a chipping gun or jackhammer. Always disconnect the tool from power source when changing accessories. Always keep both hands on the tool at all times. Watch for excess lengths in the air hose or extension cord to prevent tripping hazards. Never operate the tool without the chisel against the working surface.
