Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol.
Inhalation Risk:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
Effects of Short-Term Exposure:
Effects of Long-Term or Repeated Exposure:

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 sections Occupational Exposure Limits, EU classification, Emergency Response.
Card has been partially updated in February 2009: see Occupational Exposure Limits.
