**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. May cause fire.Highly flammable.The toxicological
properties of this material have not been fully investigated.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be harmful if absorbed through the
skin.
Ingestion:
May cause irritation of the digestive tract. The toxicological
properties of this substance have not been fully investigated. May be
harmful if swallowed.
Inhalation:
May cause respiratory tract irritation. The toxicological properties
of this substance have not been fully investigated. May be harmful if
inhaled.
Chronic:
No information found.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. 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. Strong oxidizer. Contact with other material may cause fire.
During a fire, irritating and highly toxic gases may be generated by
thermal decomposition or combustion. Will burn if involved in a fire.
Flammable liquid and vapor. Will be easily ignited by heat, sparks or
flame. Containers may explode if exposed to fire.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.
**** 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.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Avoid breathing
dust, vapor, mist, or gas. 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 mechanical shock and
friction. Do not pressurize, cut, weld, braze, solder, drill, grind,
or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from sources of ignition. Do not store near combustible
materials. Store in a tightly closed container. Store in a dry area.
Refrigerator/flammables. Keep away from reducing agents.
**** 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.
Exposure Limits
CAS# 110-05-4:
Russia: 100 mg/m3 TWA
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
