Doesn't that prove my point? Weed wackers have been around for 50 years, used by hundreds of millions of people, and the worst you could find was a freak accident that was treated successfully. I was far more likely to suffer from heat stroke than from any weed wacker related injury.

No it doesn't, it's also not the only thing that turned up when I googled 'weed wacker safety' just the most interesting. Obviously, it shows that there are more things hidden in grass than 'just pebbles' like you insisted.

Plenty of people get lacerations and other injuries from weedwackers but your employer has a duty of care to you to prevent the possibility of that happening. This has been codified by safety laws.

If you're using a weedwacker in your personal life feel free to do it nude for all I care but as others have pointed out if it's optional and unenforced that effectively means that employers won't do it.
