Does alcohol on the wet fabric do anything different with HCN? A quick searh found no reactions ot HCN with dilute or concentrated alchols. I think it's mainly the fire risk. Thanks for checking up on whether the alcohol makes the HCN gas less reactive. I didn't realize that a vodka drink could catch fire. That makes sense, if it can. |

At least that part of my memory works. -- .. Christopher A. Young Learn about Jesus www.lds.org .. |

Halon works on the fourth side of the triangle, sustained chemical reaction. Actually fire tetrahedron. Thank you Stormin' Mormon, for explaining that the proposed supposition that halon displaced oxygen was not supported in the literature. I found a similar explanation to yours in this FAA book on aircraft Fire Protection Systems: https://www.faa.gov/regulations_poli...a/ama_Ch17.pdf It's pretty troubling that some people believe stuff that has absolutely zero references in the literature that backs up their claims. I'm glad you're not one of them! As I remember from my fire protection courses, that (not displacing oxygen) was one of the advantages of halon. Of course, the government found it to be ozone toxic and outlawed it. Put that on the list of "if it works, outlaw it" along with DDT and machine guns. -- .. Christopher A.

Seems to me, an emergency kit for an airplane, could include a wash cloth of a size sufficient to cover both your nose and mouth, in a plastic bag. The use model would be that you go through airport security with the wash cloth dry. Then, when you get to the gate, you soak it from a nearby water fountain or bathroom wash sink. What else would you put in the cabin-fire emergency kit that makes sense (note that a smoke hood doesn't really make economic sense, as outlined in the papers reported). Might be best advice I've heard. Perhaps article of clothing, which has plausible deniability. Pair of new socks? -- .. Christopher A. Young Learn about Jesus www.lds.org .. |

Yes, but *if* you already have the extinguisher, you're allowed to refill it! So I bought three. One for kitchen, one for the car, and one for the electronic lab. |

A lot of people survive plane crashes, even the one where the big plane was doing cartwheels. The number who don't survive but could have if they had a survival kit is probably verrrrry low. Seems like something not worth worrying about. |
