These kits contain sodium azide which is intended to be there as a chemical sterilizing and preservative agent.
The CDC says when it comes in contact it “prevents the cells of the body from using oxygen,” facilitating cell death. “Sodium azide is more harmful to the heart and the brain than to other organs, because the heart and the brain use a lot of oxygen.” Symptoms of sodium azide exposure (via inhalation, ingestion, or skin contact) include dizziness, low blood pressure, headache, heart palpitations, skin burns and blisters, seizures, loss of consciousness, and death. If you ever suspect that you or a loved one are suffering a reaction to a toxic chemical, call Poison Control immediately at (800) 222-1222.
