I have a fairy character who can't touch iron. When I googled iron, I was shocked at how many things contain it. Apparently my education failed me somewhere and I never found out what steel was made of. One of the surprising things I found was that cars contain iron. Are there any other really, really common items like that that she'd have to avoid touching? Do doorknobs generally contain iron? I couldn't find a comprehensive list online, just general things like "transportation" or "steel."
Also, at some point she's going to be hospitalized after an accident, and I need a clueless doctor to poke a wound with something containing iron. Is it safe to say that most hospital equipment is made of stainless steel? Would a doctor use something made of steel to clean or stitch up a wound? The last time I was hospitalized for something like that I was a little kid and covered up my eyes, so I'm not sure how they got all those rocks out of my knee. :~)
