EMERGENCY OVERVIEW
Appearance: clear to white. Flash Point: -18 deg C.
Danger! Extremely flammable
liquid. Corrosive. Water-reactive. Causes eye and skin
burns. Causes digestive and respiratory tract burns. May be harmful
if absorbed through the skin.
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns. May be harmful if absorbed through the skin.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
May cause irritation of the respiratory tract with burning pain in
the nose and throat, coughing, wheezing, shortness of breath and
pulmonary edema. Inhalation may be fatal as a result of spasm,
inflammation, edema of the larynx and bronchi, chemical pneumonitis
and pulmonary edema. Vapors may cause dizziness or suffocation.
Chronic:
Prolonged or repeated skin contact may cause dermatitis.
|
Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
diately.
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. 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 not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
Notes to Physician:
Treat symptomatically.
|
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 can travel to a source of ignition and flash
back. Water Reactive. Material will react with water and may release
a flammable and/or toxic gas. Use water spray to keep fire-exposed
containers cool. Extremely flammable liquid and vapor. Containers may
explode in the heat of a fire.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. Do NOT use straight streams of
water.
Flash Point: -18 deg C ( -0.40 deg F)
Autoignition Temperature: 420 deg C ( 788.00 deg F)
Explosion Limits, Lower:1.80 vol %
Upper: N/A
NFPA Rating:
Not published.
|
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. Do not expose spill to water. A vapor
suppressing foam may be used to reduce vapors.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. Do not breathe dust, vapor, mist, or gas. Empty containers
retain product residue, (liquid and/or vapor), and can be dangerous.
Keep container tightly closed. Keep away from heat, sparks and
flame. Do not allow contact with water. Use only in a chemical fume
hood. Do not pressurize, cut, weld, braze, solder, drill, grind, or
expose empty containers to heat, sparks or open flames.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Keep under a nitrogen blanket. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from water. Flammables-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.
