 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.

    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.  Holmium
     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. Holmium nitrate exposure may cause hair loss.

   Eye Contact:  Nitric acid can cause severe eye irritation, corneal burns, permanent eye damage, or blindness.
    Severity of the damage depends on the concentration and duration of exposure. Holmium nitrate exposure may
    cause irritation.

    Ingestion:  If ingested, nitric acid can cause severe burns and damage to the gastrointestinal tract.  Intestinal
    absorption is usually poor for rare earth salts, holmium nitrate.
