I'm sure some special effects idiot has used liquid nitrogen, but we routinely use CO2 and Nitrogen gases in cylinders (usually 100# cylinders) in theater, so there may be some relevance.  We have had one death and two people rendered unconscious from CO2 this year.   The problems usually are putting the gas cylinders in small rooms or basement areas where there is not enough ventilation to insure that a release can be dispersed.  So I would want to know where the liquid nitrogen is stored and applied and, figuring worst case, what could happen if there were a big spill or release in those locations.

Subject: [DCHAS-L] Restaurant use of liquid nitrogen for ice cream?

Hi all,

A colleague, Kerri Jansen, is working on a video about using liquid nitrogen to make ice cream in a restaurant-type setting. Do any of you have experience with safety standards for this, or can you point us to a possible source? We want to make sure we do this well.

Some of the questions Kerri is looking to answer are:

Would safety guidelines for liquid nitrogen use in a restaurant differ from the standards set for lab use? If so, what differences would be taken into consideration?

What is the proper way to handle liquid nitrogen in a restaurant setting, from a safety standpoint? (Said differently, what can consumers look for to know the liquid nitrogen used to prepare their food is being handled safely?)

You can reply to Kerri directly at k_jansen**At_Symbol_Here**acs.org.

Thank you!
Jyllian
