Safety alert 09/2009 - Masonry cutting grinder causes death
In November 2008 a 39-year-old plumber died from injuries received while operating a 225mm cutting grinder (commonly know as a chasing saw).
The plumber was chasing brick walls in a bathroom of a single storey house under construction when the incident occurred.
Factors to consider
- The cutting grinder was not equipped with the appropriate handle for masonry chasing work.
- The cutting grinder was being operated above shoulder height with reduced control due to incorrect handle chosen.
- Tripping hazard.
- Never use a saw on unstable loose surfaces or around trip hazards.
- Operators need to be aware of the reactive forces (usually know as kickback) that may occur instantly and with great force, resulting in operators losing control.
- Cutting above 1.7m or shoulder height should be done from a platform or scaffold.
- Do not overreach.
- Guarding should never be altered or removed.
- Cut only as deeply as necessary.
- Use the cutting grinder in accordance with the manufacturer’s instructions.
- Refer to the Concrete and masonry cutting and drilling code of practice 2004.
