Cutting onions

[mr-rubix]

What precautions do onion peelers and cutters in factories that provide us with ready chopped onions take? Do they don full chemical gear or do they get used to peeling onions? Ok maybe machines do it but there are certainly humans around and understand that a crying and blinded workforce around dangerous big machinery would be dangerous, so how do they do it? Me personally constantly wetting the onion in hot water donning a pair of workmens goggles and stuffing tissue up my nose seems to be the best method, but is there an easier method to stop tears and discomfort? What do you do?
(Sorry for the multiple questions but I deemed this better then asking several on the same subject)

I once read that chopping onions whilst holding a slice of bread between your teeth stops the tears......I guess the bread soaks up the onion 'fumes' before they reach your eyes

Wetting the knife with cold water works for me

There was something on brainiac about this. I think they found wearing goggles or placing a wet teatowel next to the chopping board helps.

They don't affect me now.....so I think if you do it often enough your body gets used to it...
