The Hidden Rules That Shape CO Safety in Schools: Why Occupancy Types Matter More Than You Think
Carbon monoxide (CO) detection rules are inconsistent across schools, daycares, churches, camps, and athletic facilities. Buildings aren’t regulated by who uses them — they’re regulated by how the code classifies them.
And that classification, called an occupancy type, determines whether CO detection is required, optional, or never mentioned at all.
The problem? Most parents, teachers, and even administrators have no idea which occupancy type their building falls under.
