Jeff, Looks like you got many good answers so far. Just to offer my input, You should be ok with the CO2 Usage. Special Effects Co2 being colorless and odorless will not leave residue unlike
fog or
haze would. The statistics were given above for what amounts can do what to humans but in general, it will take a lot and a high concentration of CO2 to really start affecting people. CryoFX offers some more information on their website
www.CryoFX.com under the product knowledge
tab. Here you can find details on CO2 and the
safety measures which should be taken.
Regarding the transport, the DOT has their guidelines (also stated above) as well as each state. The number one
safety concern about vehicles is transporting and storing the co2 in a correct manner. That is, keeping it from being to extreme temperatures in a fast period of time. Although tanks can withstand degrees reaching in the very low 100s, going from 85 degrees to 110 degrees in minutes will cause a tank to explode. This temp difference can easily be accomplished in a car with windows up or in the trunk on a hot day, therefore always keep in mind your transporting a sleeping giant!
Im sure you have already purchased co2 jets but for those reading who are interested or thinking about obtaining some, CryoFX has many options as featured in the new scary movie 5, with pussycat dolls, and more, with very comparable pricing.
