Yesterday at 7:30 a.m., a carbon monoxide detector sounded in a Midwood apartment building. A tenant told the Daily News, "When I got up, I was dizzy," and it turns out there were "130 parts per million of carbon monoxide in the air... The FDNY evacuates buildings when carbon monoxide levels are more than 10 parts per million." The cause? A faulty basement boiler, which was turned on by the super at 6 a.m.; luckily, no one was hurt. Make sure you have a carbon monoxide detector (and make sure the batteries work) and follow these tips from the FDNY.
