Engineering Controls:
Avoid creating dust.
Local exhaust ventilation is usually not required.
If cutting or grinding material after it has hardened, water can be used as a dust
suppressant.
Personal protective equipment
Respiratory protection: Usually not required when working with virgin product, but
take measures to minimize dust exposure. May be required, depending on work done,
for grinding or cutting material after it has hardened.
For protection against irritation from dust or up to ten times the recommended exposure
limits, use a NIOSH-approved N-95 filtering facepiece or a half mask respirator
equipped with N-95 filters. A more protective respirator (e.g., P100 filters or full face
respirator) may be substituted.
Skin protection: Avoid any skin contact, particularly when skin may be wet from sweat.
Wear any water-impermeable gloves such as PVC gloves, particularly for prolonged
contact. Wear waterproof boots, high enough to prevent any cement from getting into
them. Promptly wash off of skin and remove contaminated clothing.
Eye protection: Safety glasses with side shields. If used in dusty or windy conditions,
goggles are recommended.
Section 9: Physical and Chemical Properties
