What Are the Symptoms of Sodium Nitrate Poisoning?

Sodium nitrate is an odorless chemical that generally takes the form of white or yellow crystals or granules. It is used in making potassium nitrate, fertilizers and explosives. Sodium nitrate poisoning can be caused by exposure to the chemical either through inhalation, ingestion or skin contact.

Ingestion

• Ingesting sodium nitrate can cause poisoning. Symptoms include irritation of the mouth, esophagus and stomach; noticeably bluish skin or mucous membranes; nausea; dizziness; vomiting; collapsing; spasms of abdominal pain; rapid heart beat; irregular breathing; coma; convulsions; and death due to circulatory collapse. One to two g of sodium nitrate can be lethal. Medical professionals may advise that vomiting is induced.

Inhalation

• Inhaling sodium nitrate causes similar symptoms as ingesting it. If a person has been poisoned due to inhaling sodium nitrate, get him to an area with fresh air and administer artificial respiration if necessary. Seek emergency medical services.

Skin Contact

• Red, painful or irritated skin may indicate that sodium nitrate has been absorbed through the skin, particularly if accompanied by nausea, vomiting, dizziness and blue-tinted skin If sodium nitrate poisoning through the skin is suspected, flush the irritated area with water for 15 minutes. Remove any clothing that has come into contact with sodium nitrate and wash before wearing again. If irritation persists or worsens, seek medical attention.
