**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns. Irritating to respiratory system.
Potential Health Effects
Eye:
May cause irreversible eye injury. Vapor or mist may cause
irritation and severe burns. Contact with liquid is corrosive to the
eyes and causes severe burns.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration. The severity of injury depends on the concentration of
the solution and the duration of exposure.
Ingestion:
Causes severe digestive tract burns with abdominal pain, vomiting,
and possible death. May cause corrosion and permanent tissue
destruction of the esophagus and digestive tract.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema. Causes
chemical burns to the respiratory tract. Inhalation may be fatal as
a result of spasm, inflammation, edema of the larynx and bronchi,
chemical pneumonitis and pulmonary edema.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
inhalation and ingestion may cause effects similar to those of acute
inhalation and ingestion.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at 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:
POISON material. If inhaled, get medical aid immediately. Remove
victim to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
Notes to Physician:
**** 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. Not flammable, but reacts with most metals to form
flammable hydrogen gas. Use water spray to keep fire-exposed
containers cool. Vapors may accumulate in confined spaces Approach
fire from upwind to avoid hazardous vapors and toxic decomposition
products.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Provide ventilation. Spill may be
carefully neutralized with lime (calcium oxide, CaO). Evacuate
unnecessary personnel. Approach spill from upwind. Do not use metal
tools.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing. Do
not ingest or inhale. Keep away from strong bases and metals. Do not
use with metal spatula or other metal items. Do not breathe vapor or
mist. Use only with adequate ventilation or respiratory protection.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep away from metals. Corrosives area. Store protected
from light and air. Store away from alkalies. Separate from
oxidizing materials.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower. Use a
corrosion-resistant ventilation system.
