EMERGENCY OVERVIEW
Appearance: yellow to brown clear liquid. Flash Point: 23 deg C.
Danger! Causes burns by all exposure routes.
Heating may cause an explosion. Reacts violently with water.
Flammable liquid and vapor.
Target Organs: Respiratory system,
gastrointestinal system, eyes, skin, mucous membranes.
Potential Health Effects
Eye:
Causes severe eye burns.
Skin:
Causes skin burns. Substance is readily absorbed through the skin.
Ingestion:
Causes gastrointestinal tract burns. May cause burning sensations,
coughing, wheezing, laryngitis, shortness of breath and headache.
Inhalation:
Causes chemical burns to the respiratory tract. May cause asthma and
shortness of breath. May cause burning sensation, coughing, wheezing,
laryngitis, shortness of breath, headache, nausea, and vomiting.
Chronic:
No information found.
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.
Ingestion:
Do not induce vomiting. Get medical aid immediately. Call a poison
control center.
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 victim ingested or inhaled the
substance; induce artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory
medical device.
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. Reacts violently with water.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide. DO NOT USE WATER!
Flash Point: 23 deg C ( 73.40 deg F)
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 3; Flammability: 3; Instability: 2; Special Hazard: -W-
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. Wear a self contained breathing
apparatus and appropriate personal protection. (See Exposure
Controls, Personal Protection section). Remove all sources of
ignition. Use a spark-proof tool. Do not expose spill to water. Do
not get water inside containers. Do not let this chemical enter the
environment.
Section 7 - Handling and Storage
|
Handling:
Do not allow water to get into the container because of violent
reaction. Use spark-proof tools and explosion proof equipment. Do
not get in eyes, on skin, or on clothing. Keep away from heat,
sparks and flame. Do not ingest or inhale. Do not allow contact with
water. Use only in a chemical fume hood.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Store in a dry area. Flammables-area. Store in freezer.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use only under a chemical fume hood.
