> I have never personally seen laboratory safety training materials discuss that the trainee or his/ her coworkers may freeze, panic, or do something completely wrong in an eme rgency situation.

The training I described in an article in th e Journal of Chemical Health and Safety (Volume 17, Issue 6, November-Decem ber 2010, Pages 29-32) includes this consideration in discussing lab emerge ncy response. This is the required classroom training for UVM lab workers a nd we had probably 1000 people take it over 5 years. In it, I included a di scussion about why the victim of a spill or injury is probably not the best person to make the decision about how to manage it and suggested that thei r neighbors should help organize the response. Over the course of the 5 yea rs we did that training, we had a number of responses to lab situations tha t went better than I would have expected before that training was put into place. We had some other ones as well - as others have noted, there is no g uarantee that what is talked about in training will be applied in the momen t.
