Section 3 - Hazards Identification
|
EMERGENCY OVERVIEW
Appearance: colorless clear liquid. Flash Point: -3 deg C.
Danger! Flammable liquid and
vapor. Breathing vapors may cause drowsiness and
dizziness. Causes eye and skin irritation. Toxic to aquatic
organisms, may cause long-term adverse effects in the aquatic
environment. Aspiration hazard if swallowed. Can enter lungs and
cause damage. May cause respiratory tract irritation.
Target Organs: Central nervous system, lungs,
eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May be harmful if absorbed through the skin.
Ingestion:
Aspiration hazard. May cause irritation of the digestive tract. May
be harmful if swallowed. May cause lung damage.
Inhalation:
May cause respiratory tract irritation. May cause narcotic effects
in high concentration. May be harmful if inhaled. Inhalation of
vapors may cause drowsiness and dizziness.
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.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. If
vomiting occurs naturally, have victim lean forward.
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.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use foam, dry
chemical, or carbon dioxide. Water may be ineffective.
Flash Point: -3 deg C ( 26.60 deg F)
Autoignition Temperature: 285 deg C ( 545.00 deg F)
Explosion Limits, Lower:1.2 vol %
Upper: 6.7 vol %
NFPA Rating:
(estimated) Health: 2; Flammability: 3; Instability: 0
|
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 let this chemical enter the
environment.
|
Section 7 - Handling and Storage
|
Handling:
Use spark-proof tools and explosion proof equipment. Do not get in
eyes, on skin, or on clothing. Take precautionary measures against
static discharges. Keep away from heat, sparks and flame. Do not
ingest or inhale. 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. Flammables-area.
|
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.
