**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes.
Potential Health Effects
Eye:
Causes severe eye irritation. May cause transient corneal injury.
Skin:
Causes skin irritation. Prolonged and/or repeated contact may cause
defatting of the skin and dermatitis.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause headache. May cause unconsciousness. May cause
central nervous system depression.
Inhalation:
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion. May cause narcotic effects in high
concentration. Overexposure may produce irritation of the nose and
throat.
Chronic:
Prolonged or repeated skin contact may cause dermatitis.
**** 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 immediately.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Flammable liquid and
vapor. Containers may explode when heated. 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.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate 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.
Provide ventilation. Use only non-sparking tools and equipment.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Take precautionary measures against static discharges.
Keep container tightly closed. Keep away from heat, sparks and flame.
Do not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames. Use only with
adequate ventilation. Avoid breathing vapor or mist.
Storage:
Keep away from sources of ignition. Keep from contact with oxidizing
materials. Store in a cool, dry, well-ventilated area away from
incompatible substances.
**** 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. Ventilation fans and other electrical
service must be non-sparking and have an explosion-proof design.
