Question: You are to complete an evaluation of the employee's current exposure by determining the employee's exposure to hexane (toxic contaminant) by calculating time-weighted average (TWA) and comcomparingpare it to the permissible exposure limit (PEL) and modify the PEL, if necessary. If it is necessary to modify the PEL, explain the reasoning why it is to be modified. An employee working in a room measuring 15 ft x 20 ft x 15 ft sprays paint assembly parts using a paint containing hexane. The PEL for hexane is 500 ppm. The employee wears a half-face, air-purifying respirator, but management would like to install engineering control measures to reduce or eliminate the employee's exposure to hexane.
