Of course, we (i) get reminded of the dangers of such equipment
I was cutting up a steel frame once...standing on the metal beam, cutting with a 7 inch grinder, feet planted either side.
The beam must have folded in on itself, and instantly trapped the disc (something you DONT want to happen). Well this time it did, and the disc disintegrated in a millisecond, i was enveloped in the same millisecond, in a cloud of grey dust. Bang......so quick, you dont have time to react
.
Got away with it luckily.
Also, i was at the local casualty one evening.....a young guy was sitting forlornly with a whopping gash across his forehead.....
He'd been cutting the roof off a car with a disc cutter...the disc bit, flew up and sliced across his head
A gentle reminder that respect is due with these tools.
