Computer running in tented home?
Is it safe to leave a computer running (as a server) in a home that is
being tented for fumigation? |

Heck, that's one way to debug a server. Only, I'd be sure to leave it running for at least 48 hours straight after fresh air has been restored to the building. I don't think it will hurt the computer. I'd be curious as to what the home is being fumigated with though .. . . I'd hate to have flammable fumes sucked through a hot power supply, for example. -Dave |

ARE YOU OUT OF YOUR MIND?
first of all they are going to shut off the electricity before they gas it. WHY? cause the concentrated gas is combustible. you have never heard of people bombing their house with even the cheap foggers and doing an overkill of ten foggers..then the water heater kicks on or the vapors reach the forgotten pilots on the stove..gas and power are going to be shut off.

That's why I was asking if the **** was flammable. I've never heard of houses blowing up from overkill of cheap foggers. But it would make sense, if the stuff was flammable. -Dave |

Somebody has a cockroach problem, and instead of hiring a professional they use 10 or 20 of the foggers. House is lifted right off of the foundation. Humorous, really. |

Well, it DOES solve the roach problem, doesn't it? In Olden Times, aerosol cans were pressurized with Freon - non-explosive but bad for the environment. When laws stopped that, the industry switched to stuff like butane and a new problem arose. |

Hard drive internals need to breathe, but are not ventilated as such.
o They have a small hole to equalise pressure between inside & outside o Hence the name "breather hole", also called "do not cover" :-) The breather hole is not a vacant hole, but has a filter membrane over it: o The filter membrane is porous to air molecules for pressure equalisation o It is non-porous to any solid matter large enough to cause a head crash That said I recall manufacturers do not advise the use of drives in very severe particulate environments - perhaps as much re membrane clogging. There is no "conventional airflow" - merely as the drive heats/cools it will cause air inside it to expand/contact - and migrate out/in across the filter. Hard drives often cite a limit to usage based on altitude: o That might be related to drive internal air pressure ---- since the head floats on a thin layer of air o It might also be due to air density, and so air mass re cooling ---- fans are constant *volume* air movement devices ---- increase altitude and so the *mass* of air moved falls Cooling is based on heat transfer to a given mass of air, so cooling at sea-level may become unsatisfactory at very high altitude. So hard-drives are not ventilated per se, they have a breather hole. Volatile compounds used in fumigation could enter a hard-drive thro the breather hole if the drive is cooling from hot to cool in that environment. Fumigation is designed to get everywhere - or it will not work. In reality I would not worry - except to adhere to fumigation guidelines :-) Hard drives are vastly more vulnerable to extremes of temperature. Power will almost certainly be disconnected since you do not want any airflow in the house to cause inadequate treatment anywhere. If they are using Butane as the propellant, that would also make things exciting. -- Dorothy Bradbury www.dorothybradbury.co.uk for quiet Panaflo fans (free shipping) |

being tented for fumigation? I don't think I'd want the gas getting into the little air holes in my hard drives. |

[rest snipped] An uncommonly cogent response. I learned stuff. Makes me remember why, long ago, I used to think Usenet was useful for something. |
