Have the answers at your fingertips. The potential dose of a contaminant is the product of the contaminant concentration, inhalation rate, exposure time, exposure frequency, and exposure duration divided by the product of averaging time and body weight. Respirators with tight-fitting respiratory inlets have half or full facepieces. They can choose a suitable respirator only after they have evaluated all relevant factors. 3. Permissible exposure limit (PEL) The Occupational Safety and Health Administration's (OSHA's) time-weighted average airborne contaminant concentration that must not be exceeded during any eight-hour work shift of a 40-hour workweek. This implies that some kind of shield is necessary between the lamp and the observer. // ]]>.
