EMERGENCY OVERVIEW
Appearance: colorless to slight yellow liquid.
Danger! Causes eye and skin burns. Causes
digestive and respiratory tract burns.
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Eye:
Causes eye burns. Causes redness and pain. May cause chemical
conjunctivitis and corneal damage.
Skin:
Causes skin burns. Causes redness and pain.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract. May cause systemic
effects.

exposure.
|
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.
Ingestion:
Get medical aid immediately. Do NOT induce vomiting. If conscious
and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
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. Use water
spray to keep fire-exposed containers cool. Containers may explode
when heated.
Extinguishing Media:
Cool containers with flooding quantities of water until well after
fire is out. Use water spray, dry chemical, carbon dioxide, or
appropriate foam.
Flash Point: > 112 deg C (> 233.60 deg F)
Autoignition Temperature: Not available.

NFPA Rating:
(estimated) Health: 3; Flammability: 1; 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. 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. Use with adequate ventilation. Do not breathe
dust, vapor, mist, or gas. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Do not ingest or inhale.
Discard contaminated shoes.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Corrosives
area. Store protected from moisture.
|
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.
