CPWR Team's Technology Featured at World of Concrete
Ergonomically friendly drill jig now commercially available 


Expo participant takes jig for a test drive

The annual World of Concrete expo in Las Vegas is one of the largest industry events in the basic trades. This year a CPWR-supported research team is making a splash with a new concrete drill jig.  The device can protect workers from dangerous hand-arm vibration - and when properly fitted with dust control technology, airborne crystalline silica - without compromising productivity.

Lines formed quickly to examine the latest product from the team of David Rempel and Alan Barr at University of California Ergonomics program. The team, having seen California construction laborers suffer fatigue and possible long-term injury while drilling hundreds of dowel holes into concrete, set out to make this task a little easier. Their invention, a heavy-duty drilling jig, is being picked up by innovative contractors across the country. And no wonder - equipped with a saddle that can accommodate two drills at once, it's not just safer for the worker but can get the job done quicker as well.

With two drills at once
ENR Magazine eyed the new tool (sold under the trade name "DrillBoss") and featured it on their Building 101 blog. CPWR's one-stop resource on how to prevent silica hazards, Work Safely with Silica, has incorporated the drill into its growing roster of commercially available equipment and controls. Check out this video of the drill in action - and spread the word about this important new technology!
