Dry ice in water off-gases carbon dioxide, which will itself have certain hazards in enclosed spaces. Carbon dioxide by sublimation (goes from a solid directly to gas without going through a liquid phase) has also caused toxicity in enclosed spaces. A certain Air Force aircraft with frozen foods in the cargo compartment comes to mind.

Usually not hazardous if outdoors, but in a confined space scenario, can be toxic or deadly.

Carbon dioxide is also not just a simple asphyxiant (displaces oxygen from the breathing atmosphere), but has other toxic properties in high enough concentrations.

Outdoors, you might consider a simple smoke grenade in a barrel and go from there. Could also do fire extinguisher training at the same time. The parrtipants would need to have proper PPE including full face-piece respiratrors, etc.

Safety FIRST. Dead or hurt rescuers don't save/assist anybody.

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!
