Emergency Overview
This product contains crystalline silica (less than 1%). OSHA considers perlite to be a nuisance dust. Inhalation of high
amounts over long periods of nuisance dust may overload lung clearance mechanism and make the lungs more vulnerable
to respiratory disease. Long term inhalation of crystalline silica dusts may cause lung cancer (Silicosis). Crystalline silica has
been classified as a probable human carcinogen (Group 2A) by IARC, a unit of the World Health Organization. This product
has been classified a carcinogen by NTP and/or OSHA.

Potential Health Effects
Inhalation: Pre-existing upper respiratory and lung disease may be aggravated. Acute inhalation can cause dryness of the
nasal passage and lung congestion, coughing and general throat irritation. Chronic inhalation of dust should be avoided.
Eye: May cause irritation (tear formation and redness) if dust gets in eyes.
Skin: Not absorbed by the skin. But may cause dryness if prolonged exposure.
Ingestion: Ingestion of small to moderate quantities is not considered harmful, but may cause irritation of the mouth, throat
and stomach.
