Coughing, sneezing and some difficulty in breathing can occur in cases of exceptional dust inhalation. Higher levels may cause a chemical pneumonia. Large doses may, however, upset the osmotic balance and cause vomiting and diarrhea as well as nitrate irritation. Symptoms of redness, pain, and severe burn can occur.
Contact can cause blurred vision, redness, pain and severe tissue burns.
Repeated exposure causes strontium nitrate to accumulate in the body and effects can persist after exposure stops. Persons on diets low in calcium may be at greater risk of absorbing more strontium nitrate. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
