A new law will require schools to install carbon monoxide detectors.
The law comes after an incident last year, where about 150 students and staff members became ill at the North Mac Intermediate School in Girard. The cause was a faulty exhaust pipe in the heating system.
A carbon monoxide detector would have alerted those in the building. While the detectors are required for many structures, schools were left out.
The new law, which takes effect next year, requires the devices in schools near equipment that can produce carbon monoxide. The gas is odorless and can be deadly.
The North Mac school installed the detectors since the incident.
Three other states have similar laws.
