Risk Phrases: 35
Section 3 - Hazards
Appearance: clear, colorless. Danger! Corrosive. Causes eye
and skin burns. Causes digestive and respiratory tract burns.
Eye: Causes severe eye burns. May
cause irreversible eye injury. Contact may cause ulceration of the conjunctiva
and cornea. Eye damage may be delayed. Causes redness, pain, and irritation.
Skin: May cause deep, penetrating ulcers of the skin.
Causes severe burns with delayed tissue destruction.
Ingestion: May cause circulatory system failure. May cause
perforation of the digestive tract. Causes severe digestive tract burns with
abdominal pain, vomiting, and possible death.
Irritation may lead to chemical pneumonitis and pulmonary edema. Causes severe
irritation of upper respiratory tract with coughing, burns, breathing
difficulty, and possible coma. Palpitation, inflammation, edema of the larynx
and bronchi, chemical pneumonitis and pulmonary edema may result from inhalation
Chronic: Prolonged or repeated skin contact may
cause dermatitis. Prolonged or repeated eye contact may cause conjunctivitis.
Section 4 - First Aid
Eyes: Get medical aid at once. Immediately flush
eyes with water lifting upper/lower lids occasionally until chemical is gone
Skin: Get medical aid at once. Immediately
flush skin with plenty of soap and water for at least 15 minutes while removing
contaminated clothing and shoes. Remove contaminated clothing to reduce further
exposure. Cover burns with a dry sterile bandage (loose, not tight).
Ingestion: Do NOT induce vomiting. Give conscious victim
2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious
person. Get medical aid at once. Medical personnel may do esophagoscopy,
irrigate injured area with 1% acetic acid to neutralize alkali.
Inhalation: Get medical aid at once. Move victim to fresh
air immediately. Give artificial respiration if necessary. If breathing is
difficult, give oxygen.
Notes to Physician: Treat
symptomatically and supportively.
Section 5 -
Information: Wear appropriate protective clothing to prevent contact
with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent
contact with thermal decomposition products. Use water with caution and in
flooding amounts. Contact with moisture or water may generate sufficient heat to
ignite nearby combustible materials.
Use extinguishing media most appropriate for the surrounding fire. DO NOT USE
Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
Spills/Leaks: Absorb spills with absorbent
(vermiculite, sand, fuller's earth) and place in plastic bags for later
Section 7 - Handling
Handling: Wash thoroughly after handling. Use with
adequate ventilation. Do not allow water to get into the container because of
violent reaction. Do not breathe dust, vapor, mist, or gas. Do not get in eyes,
on skin, or on clothing. Use only in a chemical fume hood.
Storage: Store in a cool, dry area. Store in a tightly
closed container. Keep away from strong acids. Keep away from water. Keep away
Section 8 - Exposure
Controls, Personal Protection
Controls: Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels.
