EMERGENCY OVERVIEW
Appearance: clear to slightly turbid liquid.
Danger! Corrosive. Causes burns by all exposure
routes. May be harmful if swallowed.
Target Organs: Respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye burns. Contact may cause ulceration of the conjunctiva
and cornea. Eye damage may be delayed. Causes redness and pain.
Skin:
May cause deep, penetrating ulcers of the skin. Causes severe burns
with delayed tissue destruction. Causes redness and pain.
Ingestion:
May cause severe and permanent damage to the digestive tract. May
cause circulatory system failure. May cause perforation of the
digestive tract. Causes severe digestive tract burns with abdominal
pain, vomiting, and possible death. May cause systemic effects.
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. Inhalation may be fatal as a result
of spasm, inflammation, edema of the larynx and bronchi, chemical
pneumonitis and pulmonary edema. May cause systemic effects.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Prolonged
or repeated eye contact may cause conjunctivitis. Effects may be
delayed.
|
Section 4 - First Aid Measures
|
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Discard contaminated clothing
in a manner which limits further exposure. Destroy contaminated
shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. 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. Non-combustible, substance itself does not
burn but may decompose upon heating to produce irritating, corrosive
and/or toxic fumes.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire. Cool containers with flooding quantities
of water until well after fire is out.
Flash Point: Not available.
Autoignition Temperature: Not available.
Explosion Limits, Lower: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:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Neutralize spill with a weak acid
such as vinegar or acetic acid. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not breathe dust, mist, or vapor. Do not get in
eyes, on skin, or on clothing. Keep container tightly closed. Do not
ingest or inhale. Use only in a chemical fume hood. Discard
contaminated shoes.
Storage:
Keep container closed when not in use. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from strong acids. Corrosives
area.
|
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
ventilation to keep airborne concentrations low.
