Peanuts are nasty and yes for many who have it the allergy becomes sever enough to kill with only a miner exposure to the dust (the dust is actually the protein people are allergic to).
Yes it is serious and deadly.
Don’t you think its unreasonable of people suffering from a rare disease to make reasonable accommodations to the world and not make the world meet their needs?
Of course this is a parallel to the americans with disabilities act which is frequently used to bankrupt small companies because 1 customer decided he was discriminated against. I know one blind guy who goes around looking for people he can sue.
Don't expose miners to them (why would you eat peanuts in a mine, anyway?), and nothing will be severed...
