Section 4. First Aid Measures
Eye Contact Check for and remove any contact lenses. Flush with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Cold water may be used. Get medical attention. Seek medical attention
in case of eye contact with a radioactive material.
Skin Contact In 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 Contact
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical
attention in case of skin contact with a radioactive material.
Inhalation If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical attention.
Serious Inhalation Evacuate 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. If breathing is difficult, administer oxygen. If the victim is not breathing, perform
mouth-to-mouth resuscitation. Seek medical attention in case of inhalation of a radioactive material.
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 7. Handling and Storage
Precautions Keep away from heat. Keep away from sources of ignition. Keep away from combustible material.. Do not
breathe dust. Take precautionary measures against electrostatic discharges. Wear suitable protective
clothing. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek medical
advice immediately and show the container or the label. Avoid contact with skin and eyes. Keep away from
incompatibles such as reducing agents, organic materials, metals.
Storage Keep container tightly closed. Keep container in a cool, well-ventilated area. Separate from acids, alkalies,
reducing agents and combustibles. See NFPA 43A, Code for the Storage of Liquid and Solid Oxidizers.
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. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this

Toxic Effects on Humans Acute/Chronic Potential Health Effects:
Skin: Causes skin irritation and possible ulceration.
Eyes: Causes eye irritation and possible conjunctivitis. Risk of serious injury possible.
Inhalation: Causes irritation of the respiratory and mucous membranes. It is slightly corrosive to the
respiratory (mucous) membranes. Symptoms may include coughing fits, sneezing, difficulty breathing,
burning sensation, acute aterial lesions, and pulmonary edema. It is transferred from the lungs of animals
quite slowly. A suspect carcinogen. Chronic exposure by inhalation may cause lung cancer, and kidney
damage.
Ingestion: Causes gastrointestinal tract irritation. Symptoms may include salivation, burning sensation in the
stomach, cramps, nausea, vomiting, weakness, dizziness, diarrhea, convulsions, flushed skin, sweating,
syncope, tachycardia, hypotension and state of shock possible. Being radioactive, this compound is
carcinogenic at any site of contamination on the body. Acute or chronic exposure may cause liver and kidney
damage, and blood/bone marrow changes. Chronic exposure may also affect metabolism (weight loss).
Addtional Data Concerning Uranyl Nitate:
Uranium is a highly toxic element on an acute basis. The levels for soluble compounds are based on the
chemical toxicity while the permissible body level for insoluble compounds is based on radioactivity.
