**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Irritating to eyes and skin. Harmful by inhalation.Light
sensitive.Air sensitive.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
May cause skin irritation. Prolonged and/or repeated contact may
cause defatting of the skin and dermatitis.
Ingestion:
May cause central nervous system depression, characterized by
excitement, followed by headache, dizziness, drowsiness, and nausea.
Advanced stages may cause collapse, unconsciousness, coma and
possible death due to respiratory failure. Aspiration of material
into the lungs may cause chemical pneumonitis, which may be fatal.
Inhalation:
Aspiration may cause respiratory swelling and pneumonitis. Causes
narcotic effects including headache, dizziness, weakness,
unconsciousness, and possible death.
Chronic:
Possible cancer hazard based on tests with laboratory animals.
**** 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:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse. Remove
contaminated clothing and shoes.
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:
Antidote:
None reported.
**** 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. Flammable Liquid. Can release vapors that form
explosive mixtures at temperatures above the flashpoint. Containers
may explode in the heat of a fire. Vapors may be heavier than air.
They can spread along the ground and collect in low or confined
areas.
Extinguishing Media:
This material is lighter than water and insoluble in water. The fire
could easily be spread by the use of water in an area where the water
cannot be contained. Use water fog, dry chemical, carbon dioxide, or
regular foam. Cool containers with flooding quantities of water
until well after fire is out.
**** 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. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Empty containers
retain product residue, (liquid and/or vapor), and can be dangerous.
Take precautionary measures against static discharges. 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. Store in a cool place in the
original container and protect from sunlight.
Refrigerator/flammables.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
