Section 3 - Hazards Identification
Appearance: white solid.
Danger! Causes eye and skin burns. May cause
severe respiratory tract irritation with possible burns. May cause
severe digestive tract irritation with possible burns. Hygroscopic
(absorbs moisture from the air).
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Causes eye burns. May cause chemical conjunctivitis and corneal
Causes skin burns. May cause deep, penetrating ulcers of the skin.
May cause skin rash (in milder cases), and cold and clammy skin with
cyanosis or pale color.
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. Causes severe pain, nausea, vomiting, diarrhea, and shock.
May cause corrosion and permanent tissue destruction of the
esophagus and digestive tract. May cause systemic effects.
Irritation may lead to chemical pneumonitis and pulmonary edema.
Causes severe irritation of upper respiratory tract with coughing,
burns, breathing difficulty, and possible coma. Causes chemical
burns to the respiratory tract.
Prolonged or repeated skin contact may cause dermatitis. Effects may
Section 4 - First Aid Measures
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Use water spray to keep fire-exposed containers
cool. Use water with caution and in flooding amounts. Contact with
moisture or water may generate sufficient heat to ignite nearby
combustible materials. Contact with metals may evolve flammable
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire. Do NOT get water inside containers.
Flash Point: Not applicable.
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.

(estimated) Health: 3; Flammability: 0; Instability: 1
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Vacuum or sweep up material and place into a suitable disposal
container. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation. Do not get water on spilled substances or inside
Section 7 - Handling and Storage
Wash thoroughly after handling. Do not allow water to get into the
container because of violent reaction. Minimize dust generation and
accumulation. Do not get in eyes, on skin, or on clothing. Keep
container tightly closed. Avoid ingestion and inhalation. Discard
contaminated shoes. Use only with adequate ventilation.
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from metals. Corrosives area. Keep away from acids. Store protected
from moisture. Containers must be tightly closed to prevent the
conversion of NaOH to sodium carbonate by the CO2 in air.
Section 8 - Exposure Controls, Personal Protection
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
