PEORIA (WEEK) -- Peoria firefighters responding to a report of a carbon monoxide alarm at a Peoria gas station instead found a leak of carbon dioxide.
The incident happened after 11 a.m. Thursday at the MacDonald Shell at 4709 North Sterling.
A release from the fire department says firefighters put on their self-contained breathing apparatus before entering the building to determine the cause of the alarm.
The inside of the store was searched for the cause of the leak while other firefighters shut off the carbon dioxide tank outside the building connected to the soda fountain.
Firefighters remained on scene for an extended period of time to ventilate the interior.
Hazmat was also called to the scene to monitor air quality inside the store.
Customers were prevented from entering the store by firefighters but gas pumps were unaffected.
No injury or illness to the store employee or firefighters was reported.
The incident was under control within 20 minutes of arrival.
