OSHA is pointing to an innovating new concrete drill jig developed by a University of California ergonomics team as a means of limiting worker exposures to respirable crystalline silica, as well reducing fatigue and risk of musculoskeletal injuries.
The jig can drive multiple large hammer drills at different angles and heights, and is mounted on a base that allows it to move easily around a construction site. A vacuum collects dust generated by the drill bit.
