Seems to me the price of our heads is rising, so why put it to risk with a hard hat when you can erect something suitable for protection? It's still economics, right? I guess there's always going to be a line drawn between profit and safety, but these days I say no to risk or even discomfort because of what I have seen of the lifestyles of those who profit from my work.
Oh, by the way I use a fibre metal clear face sheild headgear rig when I grind in the shop. If it hits the floor it falls apart 50% of the time. I've been to three big trade shows over many years and I think maybe there's no innovation in this field because of liability. If we'd ship our lawyers overseas maybe we'd get our jobs and willingness to take a risk back.
Oops, check that...the rig is a Jackson, I think. But there's more that need work. I have a Huntsman hood that every 20 cycles will send washers and bits everywhere if not re-tightened.
