Section 4. First Aid Measures
    Eye Contact        Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at    
    least 15 minutes. Cold water may be used. Get medical attention.

    waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
    resuscitation. Seek medical attention.
    Ingestion        Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an    
    unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight
    clothing such as a collar, tie, belt or waistband.

Section 8. Exposure Controls/Personal Protection
    Engineering Controls        Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below    
    recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
    airborne contaminants below the exposure limit.
    Personal Protection        Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.    
    Gloves.
    Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
    a Large Spill        to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist    
    BEFORE handling this product.
    Exposure Limits        Not available.

    Toxicity to Animals
    Special Remarks on        May cause adverse reproductive effects based on animal data.    
    Chronic Effects on Humans        May affect genetic material based on animal data.    
    May cause cancer (tumorigenic) based on animal data.
    Special Remarks on other        Acute Potential Health Effects:    
    Toxic Effects on Humans        Skin: Causes moderate skin irritation.    
    Eyes: Causes moderate to severe eye irritation.
    Inhalation: Dust may cause respiratory tract irritation, chemical pneumonia, shortness of breath and wheezing.
    Ingestion: May be harmful if ingested. May cause gastrointestinal tract irritation with nausea, vomiting and
    possible holes in the esophagus.
    The first clinical signs associated with nitrate poisoning include: Gastroenteritis, abdominal pain, nausea,
    vomiting(spontaneous vomiting), diarrhea, metabolic acidosis. Purging and diuresis can be expected. The toxicity
    of nitrates is due to the in vivo conversion to nitrites. The primary toxic effects of nitrites include orthostatic
    hypotension (due to perpheral vasodilation) and methemoglobinemia (the formation of methemoglobin in the blood
    which causes deficient oxygenation of the blood due to decreased available hemoglobin). Other symptoms may
    include muscular weakness, dizziness, lightheadness, fatigue, throbbing headache, general depression, mental
    impairment, incoordination, seizures convulsions, bradycardia or tachydardia (slow or fast heart beat),
    dysrhythmias, dyspnea. Furthermore, methemoglobinemia due to inadequate oxygenation of the blood can lead to
    progressive cyanosis, and coma. Cyanosis is first visible as a bluish discoloration of the mucous membranes and
    unpigmented areas of the body.
    Chronic Potential Health Effects:
    Ingestion: Under some circumstances methemoglobinemia occurs individuals when the nitrate is converted by
    bacteria in the stomach to the nitrite. Nausea, vomiting, dizziness, rapid or slow heart beat, irregular breathing,
    convulsions, symptoms similar to acute ingestion, coma and death can occur should this conversion take place.
    Repeated or prolonged ingestion may also affect the liver and cause anorexia (weight loss).
