View Diary: Three people killed in NC hotel by CO-leaking pool heater installed without a permit (117 comments)

  •  Pumps kill people . (9+ / 0-)

    There are great safety dangers re pools / hot tubs and pumps .
    You can electrocute people with a bad pump / install .
    You can suck the guts out of people with a bad pump / install .

    I take it this hotel had no CO sensors anywhere either.

    The search warrant documents state that police seized ice buckets, a video tape, two sections of heater exhaust pipe, a blue binder containing pool records, a wood clipboard containing room maintenance records and a GD-21 model combustible gas alarm.

    Detects many combustible gases: Natural Gas, LP, Propane, Butane, and Gasoline Fumes.
    Standard Calibration setting is 25% of LEL (Lower Explosive Limit) for natural gas (for other calibrations, please call)
    Loud Buzzer (similar to a smoke alarm buzzer) wakes even heavy sleepers.
    They had a "combustible gas alarm" at least .
    I don't know that that it would go off for CO .

    •  Pretty sure it won't- that thing's looking for (14+ / 0-)

      unburnt fuel ( usually poor combustion), not normal combustion by-product.

      Gonna turn out that the drafting on that exhaust pipe was insufficient.

      Really stupid reason for people to die.

        That and the inspection / testing .

      •  CO is a byproduct of INCOMPLETE combustion (1+ / 0-)

        If you oxidize hydrocarbons completely, you should get essentially zero CO.

        And certainly not enough to kill people in a hotel.

        That device is for catching it when you're paying for fuel that's not being used in burning. It's to save money.

      •  After thinking about it , it does in a way . (0+ / 0-)

        If it senses any combustible gas coming from the exhaust indoors , and exhaust contains CO , you could say that in a way it is detecting the fact that there is CO . If it detected zero combustible gas coming from the exhaust indoors , zero exhaust is leaking from the unit , it would follow that zero CO is leaking from the unit .

        It is not suggested to locate gas detectors in kitchens or bathrooms, because of frequent unwanted alarms due to the normal use in those rooms of products containing combustible gases.

        •  If you had CO release, but no combustible, it'd (0+ / 0-)

          zero.

          You're making the assumption that leakage will be combustible. If it's just CO, CO2, and H20, well, none of those things are combustible.

          •  No combustion is 100% . (0+ / 0-)

            Some unburnt is in the exhaust .

            If that unburnt fuel is detected , then CO is there also .

            You're making the assumption that leakage will be combustible
            Am I ? I don't think so .
            If you had CO release, but no combustible, it'd zero.
            How could you have CO and no "combustible" ?

            If you had a fuel burn of 100% ?
            But when does it ever happen in real life ?

          •  As a test , (0+ / 0-)

            lets say you have a sealed room
            with one exhaust pipe running through it .
            You test the air inside the room daily .
            One day you find that there is a small amount of fuel in the air and it could only come from the exhaust pipe .
            Is there , without testing , increased CO levels in that room .

            Another test ,
            You go in one day and find that the CO level as shown on a meter has gone up in the room but there is no unburnt fuel .
            What has gone wrong ?
