Section VI - Health Hazard Data
ROUTES OF Inhalation? Yes Skin? Yes Ingestion? Yes
ENTRY
HEALTH HAZARDS (Acute and Chronic): Concentrated Nitric Acid vapor is an irritant to the eyes, skin and upper respiratory tract. The sample solution may cause
irritation if inhaled, ingested or absorbed through the skin. A burning sensation may occur. With concentrated Nitric Acid, these symptoms are very severe. Repeated
and prolonged contact with concentrated Nitric Acid can result in mouth and bronchial problems. Prolonged skin contact results in dermatitis.
COMPONENTS LISTED AS CARCINOGENS OR POTENTIAL CARCINOGENS: N/A
SIGNS AND SYMPTOMS OF EXPOSURE: Irritation of the eyes with coughing and burning sensation on skin.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Bronchial problems and sensitive dermatitis.
EMERGENCY AND FIRST AID PROCEDURES: Seek medical assistance for treatment, observation and support if necessary.
Eye Contact: Wash eyes immediately with large amounts of water, occasionally lifting upper and lower lids, until no evidence of chemical remains (at least 15-20
minutes). Continue irrigating with normal saline until pH has returned to normal (30-60 minutes). Cover with sterile bandages. Get medical attention Immediately.
Skin Contact: Remove contaminated clothing and shoes immediately. Wash affected area with soap or mild detergent and large amounts of water until no evidence of
chemical remains (at least 15-20 minutes). In case of chemical burns, cover area with sterile, dry dressing. Bandage securely, but not too tightly Get medical
attention immediately.
Inhalation: Remove from exposure area to fresh air immediately. If breathing has stopped, give artificial respiration. Maintain airway and blood pressure and
administer oxygen if available. Keep affected person warm and at rest. Treat symptomatically and supportively. Administration of oxygen should be performed by
qualified personnel. Get Medical Attention Immediately.
Ingestion: Do not use gastric lavage or emesis. Dilute the acid immediately by drinking large quantities of water or milk. If vomiting persists, administer fluids
repeatedly. Ingested acid must be diluted approximately 100 folds to render it harmless to tissues. Maintain airway and treat shock. (Dreisbach, Handbook of
Poisoning, 12th Ed.) Get Medical Attention Immediately. If vomiting occurs, keep head below hips to help prevent aspiration.
Section VII - Precautions for Safe Handling and Use
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Do not touch spilled material. Stop leak if you can do so without risk. For small spills, take
up with sand or other absorbent material and place into containers for later disposal. For small dry spills, with a clean shovel place material into clean dry container and
cover. Move containers from spill area.
WASTE DISPOSAL METHOD: Observe all Federal, State and Local Regulations when storing or disposing of this substance. For assistance, contact the district
director of the Environmental Protection Agency.

materials.
OTHER PRECAUTIONS* Material may burn but does not ignite readily. Flammable, poisonous gases may accumulate in tanks and hopper cars. May ignite
combustibles (wood, paper, oil, etc.).
Section VIII - Control Measures
RESPIRATORY PROTECTION (Please specify): The following respirators are recommended based on information found in the physical data, and Health Hazards
