I don't know the circumstances behind the complaint that triggered the inspection (be it a disgruntled employee or someone who opposes E-cigs) but now the seed has been planted. I work for Boar's Head Provisions (the deli meat) managing their Process Safety Management program (OSHA required program for their ammonia refrigeration system). A large part of my job is following the trends of OSHA's citations, with OSHA losing federal funding they are getting very aggressive with their citations, I would consider this fair warning to all the suppliers, cover your 6 as far as your safety practices go. We don't need another government agency causing us headaches. You can actually view the citations at the link below, there are 2 different PDFs you can view.

While I hate this, self regulation is the best policy.
