EMERGENCY OVERVIEW
Not available.
Target Organs: Respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes severe eye irritation. May cause blindness. Causes redness
and pain.

Section 4 - First Aid Measures
|
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and 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. Wash mouth out with water.
Inhalation:
Remove from exposure and move to fresh air immediately. 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. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Will burn
if involved in a fire. Containers may explode in the heat of a fire.
Flammable liquid and vapor.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use foam, dry
chemical, or carbon dioxide. DO NOT USE WATER!
Flash Point: -13 deg C ( 8.60 deg F)
Autoignition Temperature: 404 deg C ( 759.20 deg F)
Explosion Limits, Lower:5.50 vol %
Upper: 10.40 vol %
NFPA Rating:
4 - health, 3 - flammability, 2 - instability, water reactive
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. Remove all sources of ignition.
Use a spark-proof tool.
Section 7 - Handling and Storage
|
Handling:
Use spark-proof tools and explosion proof equipment. Avoid breathing
dust, mist, or vapor. Avoid contact with skin and eyes. Do not allow
contact with water. Use only in a chemical fume hood.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Keep under a nitrogen blanket.
Flammables-area.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
