Residents of home safe from CO leak thanks to alarms installed by local fire dept

On Friday night our crews were dispatched to a home in the area of Lafayette Street for smoke/carbon monoxide alarms sounding. They were met by an elderly resident who said she went to bed and was awoken by the alarms. Crews entered the residence with our explosive gas meter (this meter detects levels of oxygen, explosive gas, carbon monoxide, hydrogen cyanide and hydrogen sulfide). They immediately got readings of carbon monoxide and lowered levels of oxygen in the home. Crews backed out and donned SCBA’s. Readings of carbon monoxide in the home were around 600 parts per million (it should be 0, acceptable levels are below 9 parts per million in a home). Carbon monoxide is a poisonous, order less, colorless byproduct of combustion. After a thorough investigation, it was found that the resident mistakenly left her car running in a closed garage, likely for at least 4 hours. Liberty utilities was called to the scene as a precaution, extra firefighters were called into the station due to extensive time on scene, and the home was vented with a battery powered ppv fan until there were 0 parts per million of carbon monoxide in the home. The resident was transported by our rescue to a local hospital because of slight confusion and having detectable levels of carbon monoxide in there system. If the resident had not been alerted by the properly working smoke/carbon monoxide alarms they would have passed away within hours (likely an hour).
