Mkihail, That happened to a Judge and legal staff in a Boston court building in the 1990s after a two-component urethane water proofing job went wrong. They ended up tearing down the building.
if you've ever seen this reaction, as I have, it is impressive. There is no way it can be faked. And if they hang around long, the face and eyes may also swell.
In this Boston case, however, a lot of air monitoring was done and the isocyanates were clearly present.

Very interesting. We had similar situation with an administrator who worked in an office located within a laboratory building. No longer the staff can enter
the building without having a rash and face-flushing. They did all kind of testing and monitoring without finding out the real cause. Eventually, the staff had to be relocated.

Right on Kay. And even if she had a skin reaction to nickel, that FEV1 says something dramatic happened. And she can't even go in the building? I only see that
kind of face-flushing, FEV1-dropping reaction in workers exposed to the major nasties like the isocyanates and certain dyes.

The original report indicated that one of the reactions she had was to her
earrings. This suggests that previously she had had no reaction to the nickel
in the earring posts, so the sensitization does appear to be related to the
material being in nano form.
Just a guess.

The report is based on a single case and the fact that the symptoms arose after
work with Ni nano-particle began; she had previously worked with non-nano Ni.
For a particular incident, I'm not sure how you would determine whether the nano
aspect exacerbated the situation. It's more of a suggestive data point report
than a conclusive study...
