On Mon, 21 Apr 2008 11:17:11 -0600, "Roger Helio" wrote this crap: Pyrene fire extinguishers where the defacto fire extinguisher aboard boats up until the 1950's. http://www.vintagefe.com/chriscraft.html Two problems: 1. They used carbon tetrachloride as the agent which affects the human brain ("mad hatter"). 2. When used on burning magnesium, phosgene (nerve gas) was generated. Today, a powder substance also called "Pyrene" is used for class D extinguishers which include magnesium fires. However, I don't believe it is carbon tet. I would recommend mariners carrying a Class D extinguisher as well as filling the mast with concrete for fire protection. It's been a while since I took organic chemistry, but I still remember that carbon tet, (CCL4 ) is highly flammable. Not to mention, poisonous. I'm Horvath and I approve of this post. Didja miss the part where he suggested filling the mast with concrete? |
