Text For Citation: 01 Item/Group: 001A Hazard:
The violations listed below are grouped together as a single violation because they describe different aspects of a particular hazard that may increase the potential for occupational illness resulting from exposure to a toxic material. 29 CFR 1910.1000(a)(2): Employee(s) were exposed to an airborne concentration of carbon monoxide listed in Table Z-1 - Limits for Air Contaminants, in excess of the 8 hour Time Weighted Average concentration of 50 ppm: Specifics: Employees working stocking shelves in the supermarket on the overnight shift on 10/2/2013 were exposed to levels of carbon monoxide generated by the operation of a propane-powered concrete cutting saw inside the store. The exposures were at concentrations in excess of the OSHA Permissible Exposure Limits given in Table Z - 1 as detailed below: a) The Supervisory Stock Clerk was exposed to carbon monoxide (CO) concentrations averaging 273 ppm during a 450 minute work period. This assessment is based upon a documented carboxyhemoglobin (COHb) pulse oximeter sample of 22 % COHb obtained on the employee approximately 96 minutes following the exposure period. The carbon monoxide exposure concentration as averaged over an 8 hour work shift (assuming zero exposure for the non-work periods and for the time before the concrete saw was in operation) was calculated to be 256 ppm (8 hr., time-weighted average). This exposure exceeds the OSHA Permissible Exposure Limit (PEL) for carbon monoxide (which is 50 ppm) by a factor of 5.1 times. b) A Stock Clerk was exposed to carbon monoxide concentrations averaging 206 ppm during a 360 minute work period. This assessment is based upon a documented COHb blood sample of 11 % obtained approximately 280 minutes following the exposure period. The carbon monoxide exposure concentration as averaged over an 8 hour work shift (assuming zero exposure for the non-work periods and for the time before the concrete saw was in operation) was calculated to be 154 ppm (8 hr., time-weighted average). This exposure exceeds the OSHA Permissible Exposure Limit for carbon monoxide by a factor of 3.1 times.
