Re Theatrical Fog: Just came home after 5 hours of deposition in a case of an alleged death attributed to theatrical fog. If people are going to breathe this stuff, there are professional theatrical standards for use that are recommended by the manufacturers. Visit and find their standards download feature and look for ANSI E1.5, E1.14, E1.23 and E1.29.  E1.5 will provide the TWA and peak (ceiling) limits recommended.  I recommend even less, but then......

You will also need to rent a Thermo MIE PDR-1000AN particle counter and use the calibration factor for the particular machine and type of fog you use.  

If you need advice, I'm here.

Gas rescue training in the steel industry uses theatrical fog. But you need to train people to a high level before using it, since the visibility problem adds a whole new dimension. Several years ago one company stupidly decided that everyone who worked in a gas hazard area should be trained in gas rescue. They gave people very limited training in SCBA use - basically how to don it - then threw them into a simulated rescue with a mannequin in a dark, foggy space. One worker died of a heart attack.

Subject: [DCHAS-L] Gas Leak Training Input
Hi all,
I'm trying to put together a gas leak training for our ERT members and I can't quite decide how to set it up. If the gas was visible, that would be nice but I can't think of a good candidate. 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.
I already have liquid spill training planned out.
Thank you!
