I am thinking that the term jet-flaming is a relatively new term coined to describe the kind of incidents that we have observed with the rainbow demonstrations (and other similar demos).
Dave Finster and I have used the term "flash fires" to describe the same thing. In our textbook (Laboratory Safety for Chemistry Students) on p. 5-253, we discuss this and how it can be described by using the gas equation.
Thanks for doing this - and calling attention to this continued string of incidents. It is my belief that these incidents are directly related to the lack of safety education in the undergraduate chemistry curriculum - which results in ignorance about essentials in lab safety and also a missing safety ethic (caring or thinking about safety).
Way to go!. Bob

>With the help of Anna Sitek, Sammye Sigmann and Rob Toreki, we've added a web page to the DCHAS site discussing how "flame-jetting" relates to the rainbow demonstration and other uses of flammable liquids. The effort was inspired by the incident in New York City last month, but adds information from the NFPA, Not Your Turn to Burn (an organization supporting burn survivors) and the Bureau of Alcohol, Tobacco, Firearms and Explosives.
