We almost had 2 people and a dog fall victim to CO2 poisoning in the last hour in a perminant house.
They were running there generator outside there door of there house like they have done countless times before. Well with the south winds tonight the generator fumes were pushing towards the house and melted a hole in there bank and allowed fumes under the house and up through the holes in the house.
There dog started acting funny which alerted the two people inside and one of them got up and went right to the floor. Quick phone call was made and they were taken out and rushed to the hospital.
They had a CO detector that was pinned to 999 and was not alarming.
Last word is they sound like they will be ok. My point to this is pay attention to your generators and have 2 CO detectors in your house that are DIFFERENT brands mounted at different levels!
Please pass the word!
