4. FIRST AID MEASURES

Description of First Aid Measures:

    Inhalation:   If adverse effects occur, remove to uncontaminated area.   If not breathing, give  artificial
     respiration or oxygen by qualified personnel. Seek immediate medical attention.

    Skin Contact: Wash skin with soap and water for at least 15 minutes while removing contaminated clothing
    and shoes. Get immediate medical attention.  Thoroughly clean and dry contaminated clothing before reuse.
    Destroy contaminated shoes.

   Eye Contact: Immediately flush eyes, including under the eyelids with copious amounts of water for at least
    15 minutes. Seek immediate medical attention.

    Ingestion: Contact a poison control center immediately for instructions. Do not induce vomiting. Give water
     to rinse out mouth.  Never give liquids to a person with reduced awareness or becoming unconscious.   If
    vomiting occurs, keep head lower than hips to prevent aspiration.  If not breathing, give artificial respiration by
     qualified personnel. Seek immediate medical attention.

Most Important Symptoms/Effects, Acute and Delayed: Acid burns to skin, eyes, and lungs.

Indication of any immediate medical attention and special treatment needed, if necessary:  If any of the above
symptoms are present, seek immediate medical attention.

5. FIRE FIGHTING MEASURES

Fire and Explosion Hazards:  Negligible fire hazard.  See Section 9, “Physical and Chemical Properties” for
flammability properties.

Extinguishing Media:
     Suitable: Use extinguishing media appropriate to the surrounding fire.
    Unsuitable: None listed.

Specific Hazards Arising from the Chemical: Thermal decomposition will form oxides of nitrogen.

Special Protective Equipment and Precautions for Fire-Fighters: Avoid inhalation of material or combustion
byproducts. Wear full protective clothing and NIOSH approved self-contained breathing apparatus (SCBA).

Route of Exposure:   X    Inhalation     X    Skin        X    Ingestion

Symptoms Related to the Physical, Chemical and Toxicological Characteristics: Burning pain and severe skin
corrosion, and eye damage.

Potential Health Effects (Acute, Chronic and Delayed):

    Inhalation:  Inhalation of nitric acid can damage the mucous membranes and upper respiratory tract.  Short
    term exposure may cause irritation and inflammation of the upper respiratory tract, coughing, choking, sore
     throat, shortness of breath, headache, dizziness, and nausea.  Long term exposure to acid fumes may cause
   damage to teeth, bronchial irritation, chronic cough, bronchial pneumonia, and gastrointestinal disturbances.
    Lanthanum nitrate exposure may cause irritation; chronic exposure may result in itching, sensitivity to heat,
    lung damage.

    Skin Contact:  Nitric acid can cause severe skin burns.  Severity of the damage depends on the concentration
    and duration of exposure.  Effects of acid burns may be delayed. Lanthanum nitrate exposure may result in
     irritation and hair loss.
