TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough.  Avoid inhalation of dust.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 

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
ODOURLESS WHITE CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Decomposes on heating slowly >1580°C. This produces toxic and corrosive fumes including sulfur oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly. 

Effects of short-term exposure
May cause mechanical irritation to the eyes and respiratory tract. 

Effects of long-term or repeated exposure
See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 1605°C
Density: 3.96 g/cm³
Solubility in water, g/100ml at 25°C: 0.0135 (very poor) 
 

NOTES
Strontium ion has effects on the calcium content of the bones and teeth, but data concerning harmful doses of strontium sulfate are inadequate.
Occurs naturally in environment as the mineral celestine.
