and when any of these prohibited materials are/may be present, as a result of being present as a trace or impurity in
another ingredient(s), the concentration shall not equal or exceed 0.1 percent by weight of any individual coating of
the coating system. The coating components and mixed coating shall have no adverse effect on the health of
personnel when used for its intended purpose in accordance with the manufacturer's instructions. Questions
