PERLITE ICSC: 1141
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE TO GREY POWDER.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (particulate matter containing no asbestos and <1% crystalline silica) 10 mg/m as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol.

INHALATION RISK:
Evaporation at 20C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

PHYSICAL PROPERTIES
Melting point: >1093C
Relative density (water = 1): 2.2-2.4 (crude); 0.05-0.3 (expanded)
Solubility in water: poor
ENVIRONMENTAL DATA

NOTES
This card applies to perlite with <1% crystalline silica. Expanded (high temperature treated) perlite is a fluffy particulate. Depending on the degree of exposure, periodic medical examination is suggested. If perlite contains more than 1% crystalline silica then see also ICSC0808 Quartz.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
