I must agree with Odgie’s comment in RC161 on the inadvisability of removing angle grinder guards. I was a union safety representative in the aerospace industry, and remember a couple of the statistics from material provided by the Royal Society for the Prevention of Accidents (RoSPA) relating to angle grinders. Over the period 2000 to 2002, angle grinders were third in the top ten of most dangerous tools, with injuries averaging 5400 per year.
Horrible facial injuries can occur when a cutting disc shatters, so it’s not enough to simply wear eye protection, but a face shield should also be worn. These aren’t expensive, and you can get them from suppliers such as Screwfix. I know most of us complain about nanny state health and safety regulations, but search the internet for angle grinder accidents, and the pictures speak for themselves.
There is obviously more to angle grinder safety than I’ve mentioned here, so it’s worthwhile to check out some of the training videos available. Peter Cushnaghan, member 7906
