TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE      
Inhalation   Avoid inhalation of dust and mist.  Fresh air, rest. 
Skin   Protective gloves.   
Eyes   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion      

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.

IMPORTANT DATA
Physical State; Appearance
WHITE-TO-GREY POWDER. 

Physical dangers
No data. 

Chemical dangers
No data. 

Occupational exposure limits
TLV not established. 

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
 


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

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.
