**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Irritating to eyes, respiratory system and
skin.Moisture sensitive.
Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
Causes skin irritation. May cause irritation and dermatitis. May
cause cyanosis of the extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. The toxicological properties of this substance have not
been fully investigated. Ingestion of large amounts may cause CNS
depression.
Inhalation:
Causes respiratory tract irritation. The toxicological properties of
this substance have not been fully investigated. Aspiration may lead
to pulmonary edema. Vapors may cause dizziness or suffocation. Can
produce delayed pulmonary edema. May cause burning sensation in the
chest.
Chronic:
Effects may be delayed.
**** 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. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Get medical aid. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or 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 may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Will burn if involved in a fire. Use
water spray to keep fire-exposed containers cool. Water may be
ineffective. Material is lighter than water and a fire may be spread
by the use of water. Containers may explode in the heat of a fire.
Flammable liquid and vapor. Vapors may be heavier than air. They
can spread along the ground and collect in low or confined areas.
Will be easily ignited by heat, sparks or flame.
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 get water inside
containers. Do NOT use straight streams of water.
**** 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. Use a spark-proof tool. Provide ventilation. Do
not get water inside containers. 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. Avoid contact with eyes, skin, and 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. Avoid ingestion and inhalation. Use with adequate
ventilation. Do not allow contact with water. Wash clothing before
reuse. Do not pressurize, cut, weld, braze, solder, drill, grind, or
expose empty containers to heat, sparks or open flames. Keep from
contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a cool, dry, well-ventilated area away from
incompatible substances. Flammables-area. Store protected from
moisture.
**** 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 explosion-proof ventilation to keep airborne levels to
acceptable levels.
Exposure Limits
CAS# 21490-63-1:
Personal Protective Equipment

exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.
