Me as a teenager, happily cutting my grandad's hedge when the hedge trimmers just stopped. Completely dead. Odd. Checked the plug - still firmly in. Consumer unit - no tripped switch. Hmmm. Changed the fuse in the plug - still nothing. Resigned myself to a new pair of hedge trimmers. Started to tidy away the cable when I found these bare wires - as if someone had caught the cable in a pair of hedge trimmers and not realised
So - safety starts with the individual. I never touch hedge trimmers now.
