UNIONTOWN, Pa.,None — Construction crews will again work during the day at Uniontown High School now that a hospital has explained carbon monoxide levels in staff and students are not likely tied to construction equipment.
Uniontown Hospital has determined the "vast majority" of students and staff tested had carbon monoxide levels of 1.6 percent to 3 percent -- slight above the normal threshold of 1.5 percent.
Two students tested above 3 percent, but both are smokers. The hospital said carbon monoxide levels of less than 3 percent are not unusual during colder weather, because of normal fireplace and furnace use.
The district last week had suspended construction work during the school day, because of concerns that construction machinery was making students ill.
Superintendent Charles Machesky said three agencies tested every classroom in the school. Results showed either no carbon monoxide or levels in the acceptable range.
Machesky said schools aren't required to have carbon monoxide detectors in the building, but the district is planning to purchase a handheld one.
