Appropriate Engineering Controls:
Use outdoor in well-ventilated areas; otherwise employ natural or mechanical ventilation
to maintain exposure within applicable limits.
Personal protective equipment
Face and eyes: safety glasses with side shields or protective goggles should be
worn while using this product. For extremely dusty conditions, non-vented goggles
or goggles with indirect venting are recommended. Avoid contact lens wear when
using this product.
Body: Long sleeved shirts and trousers should be worn while using this material.
Wear water-proof boots. If working in dusty conditions, impervious over garments
are recommended.
Respiratory: If exposure levels cannot be maintained below an acceptable limits,
suitable particulate-filtering facemasks or respirators approved by MSHA/NIOSH
