Engineering Controls: Local exhaust can be used, if necessary, to control airborne dust levels.
Personal Protection: The use of barrier creams or impervious gloves, boots and clothing to protect the skin
from contact is recommended. Following work, workers should shower with soap and water. Precautions
must be observed because burns occur with little warning -- little heat is sensed.
