All contractors, including concrete core drillers, must be licensed by the state in which they are working, and they must comply with the U.S. Department of Labor Occupational Safety and Health Administration (OSHA) Part 1986 Construction Regulations, Part 1926 and subparts. Concrete core drilling is a method of drilling a hole in concrete using a diamond-tipped hollow drill.
Concrete core drillers must comply with OSHA's general rules---operators must be adequately trained to use the equipment and the equipment must be in safe condition. They must wear personal protective equipment (PPE), including goggles, long pants, protective noise equipment and steel-toed work boots. Operators should wear a respirator when exposed to hazardous materials, and there should be adequate ventilation.
OSHA rules state that concrete core drillers should make certain they are not drilling into electrical cables. They should use the services of the underground utility and cable locating companies prior to drilling. Concrete core drillers should maintain a distance of 10 feet from high voltage overhead power lines. Contractors must maintain all work trucks and follow safe driving habits when traveling to jobs.
Concrete core drillers must take special precautions when working on busy roads and highways. Warning and directional signs must be placed according to directions from local law enforcement officers. Night work flagger stations should be illuminated. Vehicles should be parked facing oncoming traffic, and all workers must wear visibility safety apparel as well as the regular PPE.
