If you’re responsible for a school, childcare center, campus facility, or any public building, you may have been told some version of: “Don’t worry; we have CO detectors installed.” But here’s the problem: Most buildings rely on carbon monoxide devices that weren’t designed for educational or multi-room environments. And many assume all CO detection devices work the same; they don’t.

The model building codes used in the U.S. are updated every three years, but not often regularly adopted by states, leaving tremendous gaps in safety.
