Pennsylvania –

“Carbon monoxide detectors are currently not required for child care centers in Pennsylvania, despite repeated efforts by state legislators to change that.  State Rep. Jeanne McNeill, D-Lehigh County, last year sponsored a bill for the requirement, but it languished in committee. On Friday, McNeill announced she was reintroducing her legislation, which would require one or more alarms in buildings that house child care facilities with possible sources of carbon monoxide.”
