**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable.Harmful by inhalation,in contact with skin and if
swallowed.Irritating to eyes and skin.Possible risk of impaired
fertility.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.Harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed.May cause irritation of the digestive tract.
Inhalation:
Harmful if inhaled.May cause respiratory tract irritation.
Chronic:
Not available.
**** 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.
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.If conscious drink water,then induce vomiting.If
unconscious,immediately take victim to a physician and do NOT
attempt to induce vomiting.
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:
**** 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.
**** 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.Remove all sources of ignition.
Use a spark-proof tool.
**** 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.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:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower.Use adequate
ventilation to keep airborne concentrations low.
Personal Protective Equipment
Eyes:
Wear chemical goggles.
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.Always use
a NIOSH or European Standard EN 149 approved
respirator when necessary.
