Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: colorless to yellow. Flash Point: 55 deg F.
Danger! May be fatal if inhaled. Causes severe eye
irritation and possible eye injury. Causes respiratory tract
irritation. Flammable liquid and vapor.
Lachrymator (substance which increases the flow of tears). Harmful
if swallowed or absorbed through the skin. Causes skin irritation.
May form explosive peroxides. Air sensitive. Light sensitive.
Target Organs: Eyes.
Potential Health Effects
Eye:
Causes severe eye irritation. May cause eye injury. Lachrymator
(substance which increases the flow of tears).
Skin:
Causes skin irritation. Harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea.
Inhalation:
May be fatal if inhaled. Causes respiratory tract irritation.
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 immediately. Do
NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Discard contaminated clothing in a manner which limits further
exposure.
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 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. Use
water spray to keep fire-exposed containers cool. Flammable liquid
and vapor. May be ignited by heat, sparks, and flame. Containers may
explode when heated. Approach fire from upwind to avoid hazardous
vapors and toxic decomposition products. Vapors are heavier than air
and may travel to a source of ignition and flash back. Vapors can
spread along the ground and collect in low or confined areas. Fight
fire from protected location or maximum possible distance.
Extinguishing Media:
Use water spray, dry chemical, "alcohol resistant" foam, or carbon
dioxide.
Flash Point: 55e deg F ( 12.78 deg C)
Autoignition Temperature: 450 deg F ( 232.22 deg C)
Explosion Limits, Lower:2.1
Upper: 15.5
NFPA Rating:
(estimated) Health: 4; Flammability: 3; Instability: 2
|
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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Provide ventilation. A vapor suppressing foam
may be used to reduce vapors. Water spray may reduce vapor but may
not prevent ignition in closed spaces. Evacuate unnecessary
personnel.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Do not get in eyes, on skin, or on clothing. 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 ingest or inhale. 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 heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Keep from contact
with oxidizing materials. Store in a cool, dry, well-ventilated area
away from incompatible substances. Do not store near alkaline
substances. Store under an inert atmosphere.
|
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.
