Abstract
This testimony concerns the application for permanent variance made by the St. Joe Lead Company. NIOSH has grave concerns over this request to use air purifying high efficiency half mask and full facepiece respirators for protection in lead (7439921) atmospheres up to 100 times the OSHA permissible exposure limit instead of the 10 times (half mask) or 50 times (full facepiece) the limit permitted in the current lead standard. NIOSH does not believe it is prudent to use quantitative fit test results to establish use concentrations higher than those normally accepted by OSHA. Field studies on powered air purifying respirators and one negative pressure respirator indicate that correlation between quantitative fit factors and workplace protection factors has not been demonstrated. Thus NIOSH does not recommend that fit test results be used to increase maximum use concentrations.
