Section 4. First Aid Measures
Eye ContactCheck 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.
Skin ContactIn case of contact, immediately flush skin with plenty of water. Cover the irritated skin with an emollient. Remove
contaminated clothing and shoes. Cold water may be used.Wash clothing before reuse. Thoroughly clean shoes
before reuse. Get medical attention.
Serious Skin ContactWash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical
attention.
InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get
medical attention.
Serious InhalationEvacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Seek medical attention.
IngestionDo 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.

Chronic Effects on Humans May cause damage to the following organs: blood.
Other Toxic Effects onHazardous in case of skin contact (irritant), of ingestion.
HumansSlightly hazardous in case of inhalation.

Toxicity to Animals
Special Remarks onMay cause adverse reproductive effects based on animal data.
Chronic Effects on HumansMay affect genetic material based on animal data.
May cause cancer (tumorigenic) based on animal data.
Special Remarks on otherAcute Potential Health Effects:
Toxic Effects on HumansSkin: 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).
