KSC develops Earth-friendly fire suppression agent
wrote in message news:20031105224328.QPKE2463.amsfep12- NASA-KSC has filed a patent application for the dry powder substance that combines the best properties of water and Halon fire extinguishing agents. The agent is made of microencapsulated water, which means it's not evaporated into the atmosphere making it a more powerful suppressant that's also appropriate for the environment. Sounds impressive. I wonder what the microcapsules that hold the water are made of, though. If they're made of some petroleum product, are they better than Halon? rgds Neil |

Considering Halon is banned now, yes. :-) Actually I can see a real call for this in data centers. They've been moving away from dry suppressants in some places simply because the room is so large that any people in it would risk suffocation before they could evacuate. (not to mention the clean-up cost of triggering such a system.) The solution has been a dry pipe system with separate sprinklers over each rack and flooding the system in the event of a fire and then only releasing water over specific racks, ideally isolating the damage the suppressant might cause. rgds Neil |

wow, powdered water! Like the Steven Wright joke; "I bought some powdered
water, but I don't know what to add". |

Each partition needs its own environmental control system and fire suppression system (redundant, preferably). And the multiplicity of control systems introduces headaches and costs; larger A/C units and more bottles for the basic system are a lot cheaper than more systems... -george william herbert |
