That's all because the US is such a lawsuit shithole, you can get sued for literally anything. You're the land of frivolous lawsuits.
It's possible to mis-operate machinery accidentally, then have an idiot lawyer chase your ambulance recommending you to sue the manufacturer because they didn't label it accordingly, therefore they'd be liable. Of course in most cases liability is on the person, but safety measure regulation increases meant that companies were held liable for any small mistake, including lacking appropriate labelling on products even the most mentally challenged would recognise as dangerous...
Some say it's a nanny state issue, IMO it's just a measure to force companies to make safe (as safe as possible, that is) equipment that has gone too far.
