EMERGENCY OVERVIEW
Appearance: white solid.
Danger! Causes eye and skin burns. Causes
digestive and respiratory tract burns. Hygroscopic (absorbs moisture
from the air).
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Eye:
Causes eye burns. May cause blindness. May cause chemical
conjunctivitis and corneal damage.
Skin:
Causes skin burns. May cause deep, penetrating ulcers of the skin.
Ingestion:
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.
Inhalation:
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.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Effects may
be delayed.
Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
Skin:
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.
Ingestion:
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.
Inhalation:
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
|
General Information:
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
hydrogen gas.
Extinguishing Media:
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.
Upper: Not available.
NFPA Rating:
(estimated) Health: 3; Flammability: 0; Instability: 1
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
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
containers.
Section 7 - Handling and Storage
|
Handling:
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.
Storage:
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
|
Engineering Controls:
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.
