Russ,   I don't use a lot of videos in my training, but this one is a must.  It also makes the point I have trouble getting people to understand--that heavier than air does not mean put the ventilation exhaust at the floor!   Once airborne and mixed well with air, vapors will disperse and will not resettle quickly.  It's why heavy chlorinated solvents like the Freons end up in the stratosphere..

If that vapor was generated on a table, the exhaust either has to be very close to the source or you need to exchange the room air with a dilution system.

George's video from Bowling Green is here: . It is must see viewing for anyone who thinks that open containers of mercury are a good idea.

Bowling Green State University conducted a demonstration some years ago on how mercury vapors disperse. The report is a video on the web that is fairly easy to find. It may be useful a part of a class room introduction on vapor phase release training. IMHO it graphically demonstrates that just because an SDS says vapors are heavier than air, they don't necessarily stay on the floor. It also demonstrates that some fairly expensive and sophisticated equipment (such as a mercury vacuum cleaner) doesn't control vapors from the spill. It also demonstrates good use of PPE when dealing with vapors, and by implication shows that full face air purifying respirators may not provide sufficient protection to responders. If this is old news, sorry to waste your time.

A couple of other thoughts -

Depending upon what the goals of the training are - you might want to consider - leak recognition. Having done lots of leak detection and repair training, it always amazed me that individuals did not recognize that an ice ball around a valve in 100 degree F temps meant escaping gas. And I have also used essential oils (like peppermint) to get someone to recognize a leak and how vapor travels (and it doesn't take much.)

I would suggest contacting a local compressed gas supplier - preferably one of the big ones like Airgas or Praxair. Airgas does this sort if training routinely, and even has some good videos to show. We also have emergency response teams all over the country who may be able to assist.

Lastly Airgas has a fantastic website for training responders about compressed gas emergencies:

Have any of you done anything like this? If so, any ideas or input into how to get this training onto it's feet would be much appreciated.
