An operation spray-paints large aircraft wings using a paint containing hexavalent chromium. Summarize the different types of engineering controls, administrative controls, and personal protective equipment that could be used to control the exposures for this operation. State which control you believe would be the most effective to reduce the risk in the painting operation to an acceptable risk level. Which additional controls would you use if your initial control did not reduce the risk to an acceptable level ‌‌‌‍‍‌‍‌‌‍‍‌‍‍‌‌‌‍‍ ?
