Playing with Fire: Chemical Safety Expertise Required – submitted by Milan Sanader

This recent article from the Journal of Chemical Education is an excellent overview of accidents that have happened involving flammable liquids.  The authors report 164 children and educators have been injured over a 20 year period.  The article also provides useful insights into why these accidents occur and measures necessary to prevent them.

In my opinion, this article is a “must read” for any science teacher considering bringing a sample of a flammable liquid into their classroom.
