EMERGENCY OVERVIEW
Not available.
Appearance: colorless clear liquid. Flash Point: -7 deg C.
Not available.
Target Organs: Central nervous system, liver,
respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation. May result in corneal injury.
Skin:
Causes mild skin irritation. May be absorbed through the skin.
Repeated or prolonged exposure may cause drying and cracking of the
skin.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
May cause respiratory tract irritation. Inhalation of vapors may
cause drowsiness and dizziness.
Chronic:
Chronic inhalation may cause effects similar to those of acute
inhalation.
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. Do NOT allow vi
ctim to rub eyes or keep eyes closed.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
Ingestion:
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 can travel to a source of ignition and flash
back. Will burn if involved in a fire. Flammable liquid and vapor.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.
Flash Point: -7 deg C ( 19.40 deg F)
Autoignition Temperature: 404 deg C ( 759.20 deg F)
Explosion Limits, Lower:1.8 Vol %
Upper: 11.5 Vol %
NFPA Rating:
(estimated) Health: 1; 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. Avoid runoff into storm sewers and
ditches which lead to waterways. 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. Avoid breathing
dust, vapor, mist, or gas. Avoid contact with skin and eyes. Take
precautionary measures against static discharges. Avoid ingestion and
inhalation.
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:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
