8.2 EXPOSURE CONTROLS/PERSONAL PROTECTION
Ventilation: Use adequate ventilation to keep exposure to dust below recommended exposure levels. Avoid inhalation of dust. The
highest probability of silica exposure occurs during installation using dry cutting methods or during removal of installed natural stone
tile. Wet cutting methods are recommended.
Respiratory Protection: Use of a properly fitted NIOSH/MSHA approved particulate respirator is recommended when cutting natural
stone products for installation or during the removal of installed product.
Avoid creating excessive dust. Clean up dust with a vacuum system with a High-efficiency particulate (HEPA) air filter vacuum or damp
sweeping. See Section 8 of this SDS concerning PPE information for clean-up.
When cutting, grinding or removing, use equipment with integral dust collection and/or use local exhaust ventilation. Use wet cutting
methods to reduce generation of dust. Use respiratory protection in the absence of effective engineering controls.

Eye Protection: Use dust-proof goggles or safety glasses with side shields. Contact lenses may absorb irritants. Do not wear contact
lenses in work areas.
Skin Protection: Cotton or leather work gloves should be worn when cutting this product to minimize skin exposure to dust and/or cuts.
Wash hands prior to eating, drinking, or smoking, and at the end of the work shift, after cutting operations are conducted.
