A carbon monoxide (CO) alarm alerted two Madison, Wisconsin, residents to a potentially
life-threatening situation earlier this week.
According to the Wisconsin State Journal, firefighters found out the couple had used two
charcoal grills a few hours earlier and put the grills in their garage, under the apartment.
“The couple called 911 after their alarm went off twice, but then fell silent,” said
Madison Fire Department spokesperson Cynthia Schuster.
CO is a gas you cannot see, taste, or smell. It is often called “the invisible killer,” and
is created when fossil fuels, such as kerosene, gasoline, coal, natural gas,
propane, methane, or wood, do not burn completely.
Fire officials say that firefighters opened the garage door and brought the grills
out. Once the CO reading fell to zero, the residents were allowed back into their
NFPA’s community toolkit on CO alarms, co-produced with the Consumer Product Safety
Commission, provides everything needed to motivate residents to install and
maintain CO alarms. In addition, the carbon monoxide safety page includes
safety tips and reports about the dangers of CO and preventative measures.
