29 CFR 1926.55(a): Employee(s) were exposed to airborne concentrations of styrene above 100 ppm ceiling limit as listed in the Threshold Limit Values of Airborne Contaminants for 1970 of the American Conference of Governmental Industrial Hygienists: a) On October 25, 2017, at the jobsite located at South Park Blvd. & Parkside Cir., Streamwood, IL 60107, an employee engaged in a cured in place pipe lining operation was exposed to styrene in excess of the 15 minute ceiling limit of 100 parts per million (ppm). The employee was exposed to styrene for up to four hours, working inside a 24 inch diameter horizontal sewer pipe, up to 30 feet away from the manhole. An employee was exposed to styrene at a concentration ranging between 220 - 270 parts per million (ppm), approximately more than twice the 100 ppm OSHA ceiling limit. Exposure levels were calculated from blood styrene levels obtained by the medical examiner's office. The styrene ceiling exposure limit was established to prevent eyes, skin and mucous membrane irritation, and central nervous system (CNS) depression, especially fatigue, headache, loss of coordination, muscle weakness, dizziness, and unconsciousness. In accordance with 29 CFR 1903.19(d), abatement certification is required for this violation (using the CERTIFICATION OF CORRECTIVE ACTION WORKSHEET), and in addition, documentation demonstrating that abatement is complete must be included with your certification. This documentation may include, but is not limited to, evidence of the purchase or repair of the equipment, photographic or video evidence of abatement, or other written records.
