Construction Work Causes Carbon Monoxide Buildup On East Side

Construction workers were cutting concrete in a basement on Mendota Street Monday evening when one of them became ill. He stepped outside for fresh air, and the Madison Fire Department was called.
 
Ladder 8 went inside with air monitors and came back with readings indicating high levels of carbon monoxide (122 parts per million).
 
Firefighters began initial ventilation of the basement, and the construction workers remained on site to continue ventilating. They said no more indoor concrete cutting would be done.
