BATON ROUGE - Seven people were rushed to the hospital Friday morning after a carbon monoxide exposure at their home.

Emergency officials say it’s a warning for everyone.   

Carbon monoxide is colorless, odorless, and tasteless — it's known as the "invisible killer." 

Friday morning, Baton Rouge EMS and firefighters, along with their hazmat team, arrived at the home on Brady Street to find the people all conscious, but experiencing symptoms of carbon monoxide exposure.

"Typically if you see a group of people having the same type of symptoms that's a sign that it can possibly be a gas exposure," EMS spokesman Brad Harris said.

Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, confusion and fatigue.

"What happens is when the carbon monoxide builds up in the bloodstream it will actually bind to those receptors and it causes the oxygen to not be able to be delivered to the body like it's supposed to," Harris said.

Officials recommend that people install detectors on every level of homes, test them monthly, have all gas appliances serviced annually and never use gas-burning devices inside homes, including generators and grills.

Inspectors believe this case was caused by a gas-powered heating, ventilation and cooling — HVAC — system connected to the home.

"It's not common, but it is something that can happen if appliances are maintained properly or if they're not vented properly carbon monoxide can build up in the home and cause an issue for you," Baton Rouge Fire Department spokesperson Justin Hill said.

It's unclear if the home had working carbon monoxide detectors. 

“Carbon monoxide is a gas that you're not going to taste, smell or see, the only way you're going to know its presence is if you have working detectors in the home, they need to be placed at every level of the home and the sleeping areas," Hill said.

If you experience any symptoms of carbon monoxide exposure you should get out of the home and call 911.
