Hazard Rating Key: 0=minimal; 1=slight; 2=moderate; 3=serious; Reasons for Citation 4=severe f Strontium Nitrate is on the Right to Know Hazardous Substance List because it is cited by DOT. f Strontium Nitrate can affect you when inhaled. f Contact can irritate the skin and eyes. f Inhaling Strontium Nitrate can irritate the nose, throat and lungs. f Repeated exposure may damage the lungs, heart, liver and kidneys, and affect the nervous system f Exposure to very high levels of Strontium Nitrate can cause it to accumulate in the bones and may affect their function. SEE GLOSSARY ON PAGE 5. f Strontium Nitrate is not combustible, but it is a STRONG OXIDIZER that enhances the combustion of other substances. FIRST AID Eye Contact f Immediately flush with large amounts of water for at least 15 minutes, lifting upper and lower lids. Remove contact Workplace Exposure Limits lenses, if worn, while rinsing. No occupational exposure limits have been established for Strontium Nitrate. However, it may pose a health risk. Skin Contact Always follow safe work practices. f Quickly remove contaminated clothing. Immediately wash contaminated skin with large amounts of water.

Inhalation f Remove the person from exposure. f Begin rescue breathing (using universal precautions) if breathing has stopped and CPR if heart action has stopped. f Transfer promptly to a medical facility.
