Dangers that most of the chemists deal with are overrated. Sure, there are substances that should be treated with extreme caution, but accidental & temporary exposition to small amounts of most of the chemicals used in labs is not dangerous. It doesn't mean we shouldn't pay attention or ignore risks, but loosing a sleep is overreacting.

I don't blame you. We live in a world where fear mongering and media hype make most people chemophobic.
