... Is there a special exclusion for the use of Halon in planes? I thought Halon was outlawed or common use and now required special permitting. AFAIK, halon *production* is banned. However, there's a considerable stockpile of halon left, and you can still purchase halon extinguishers. No permits required to buy. Pete |

George Patterson Treason is ne'er successful, Sir; what then be the reason? Why, if treason be successful, Sir, then none dare call it treason. |

CJ, Is there a special exclusion for the use of Halon in planes? I thought Halon was outlawed or common use and now required special permitting. Great stuff tho. Halon is not outlawed. You cannot produce it, but there are sufficient stockpiles of the stuff to make fire extinguishers for years. It is a great example of the idiocy of environmental laws. Bureaucrats would rather you burn alive than suffer a miniscule risk of getting cancer 20 years down the road. |

Actually, it was banned as a ozone-depleter, if I recall correctly. I suppose that could lead to skin cancer, but most people consider that to be the least of the concerns with respect to the ozone layer disappearing. In any case, there are other fire extinguishing agents that work just as well. Yes, they aren't necessarily as friendly to your airplane, but having to spend more money after a fire isn't the same kind of thing as making you "burn alive". Pete |

Are you seriously suggesting that the tiny quantities of halon discharged in airplane fires will have any appreciable effect on the ozone? What makes you think the other agents do not have the same or worse environmental effects? |

... Are you seriously suggesting that the tiny quantities of halon discharged in airplane fires will have any appreciable effect on the ozone? No. It's not the individual fires for which an individual canister of halon is discharged that's the problem. It's the total leakage that happens over the entire production, distribution, and storage lifetime of halon products. That said, one aspect of halon and similar agents is that a very small amount goes a very long way, in terms of depleting ozone. Because they act to encourage chemical reactions that get rid of ozone without actually being consumed in those reactions themselves (things that behave this way are known as catalysts), once ANY halon or other depleting agent gets into the upper atmosphere, it stays there for a very long time doing harm. What makes you think the other agents do not have the same or worse environmental effects? Um, because they don't. Your question is like asking what makes me think I can't use water as fuel for my airplane. The chemical agents used in fire extinguishers now are very different from halon, in that they are not catalysts for ozone-reducing reactions. In any case, I'm not here to debate the merits of halon bans with you. I was simply explaining WHY the ban exists, and the error in your assumption that a) you have to burn alive without halon and b) that cancer is the concern. You should feel free to contest the ban as much as you like, but if you don't get your facts straight everyone will just think you're an idiot. Pete |

You should feel free to contest the ban as much as you like, but if you don't get your facts straight everyone will just think you're an idiot. You are quite right. I am just an idiot who asks dumb questions. Questions like, "Halon has been banned for ten years now. Is the ozone layer coming back?" But we will let it rest. Suffice it to say that there is considerable dispute as to whether chlorofluorocarbons have had any effect on the ozone layer at all. There is certainly no hard scientific data supporting the theory. So we will re-state my assertion as, "Bureaucrats would rather that you burn alive than risk any damage to their pet environmental religious theories." |
