Dear DCHAS Listserv members:
FYI, the NIH NLM's "Enviro-Health Links - Laboratory Safety" web page has a section on K-12 School Laboratory Safety: Some of the resources might be useful for you and others, e.g., the U.S. Chemical Safety and Hazard Investigation Board's (CSB's) "Key Lessons for Preventing Incidents from Flammable Chemicals in Educational Demonstrations" Safety Bulletin ( Please feel free to suggest other resources for us to consider for the "Enviro-Health Links - Laboratory Safety."

I think DCHAS members may want to be aware of this in case they have people who like to emulate Internet videos in the organization...

This teacher leaves his students treating the floor like lava while leaving them in awe and he shows them what a little bit of liquid methane will do when lit on fire and poured onto the floor. Perhaps there's an opportunity to develop a Job Hazard Analysis of this demonstration...
