Carbon monoxide exposure in office building sickens employees - Louisiana, 2007.
La Morb Rep 2007 May-Jun; 18(3):1-2
In early 2007, an office building in Louisiana was evacuated and twelve employees received emergency medical treatment due to carbon monoxide (CO) exposure. Around 3:30 p.m., the incident was first reported to the local fire department which arrived thirty minutes later, evacuated the building and conducted a CO air analysis. The initial reading detected high levels of CO - approximately 700 parts per million (PPM) - in a stairwell. (The Occupational Safety and Health Administration's permissible exposure limit for CO is 50 ppm as an 8-hour time-weighted average in the workplace.) A second reading conducted after the building had been ventilated for approximately thirty minutes showed CO levels less than 35 ppm. Although the source of exposure is still under investigation, initial reports suggested that an improperly vented boiler introduced CO into the building.
