I would encourage the membership to read Chapter 12 of NFPA 45 Fire Protection for Laboratories Using Chemicals in its entirety before doing any demonstrations. The number of accidents this has caused led the committee to add significant restrictions and responsibilities.

On a personal opinion note, it is 2020 and why can’t you show a video instead of creating a needless hazard. While I am sure we all have vivid memories of these type demonstrations, particularly the less well planned and executed ones, how many of us can truly say this is what made us decide to go into  science? I suspect few if any. These things, particularly the larger and more spectacular scale ones, are just not worth the risk. With all due respect to Michael Faraday and all the other greats who came before us, times have changed and I don’t see anyone suggesting that we should all throw out hot plates and ovens for Bunsen burners or get ride of our cars for horse drawn carriages. I think it is time to rethink the need for hazardous demonstrations and consider if new technologies can’t allow us to do something a lot safer.
