                 **** SECTION 3 - HAZARDS IDENTIFICATION ****

                              EMERGENCY OVERVIEW
Irritating to eyes.

Potential Health Effects
         Causes eye irritation.  Effects may be delayed.  May cause
         lacrimation (tearing), blurred vision, and photophobia.  May cause
         chemical conjunctivitis and corneal damage.
         May cause skin irritation and possible burns.
         May cause gastrointestinal irritation with nausea, vomiting and
         May cause irritation of the respiratory tract with burning pain in
         the nose and throat, coughing, wheezing, shortness of breath and
         pulmonary edema. Olfactory fatigue may occur. Can produce delayed
         pulmonary edema.
         Chronic inhalation may cause effects similar to those of acute
         inhalation. Effects may be delayed.

                   **** SECTION 4 - FIRST AID MEASURES ****

         Immediately flush eyes with plenty of water for at least 15 minutes,
         occasionally lifting the upper and lower eyelids. Get medical aid.
         Flush skin with plenty of soap and water for at least 15 minutes
         while removing contaminated clothing and shoes. Get medical aid if
         irritation develops or persists. Wash clothing before reuse.
         Never give anything by mouth to an unconscious person. Do NOT induce
         vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls
         of milk or water. Get medical aid if irritation or symptoms occur.
         Remove from exposure to fresh air immediately. If not breathing,
         give artificial respiration. If breathing is difficult, give oxygen.
         Get medical aid if cough or other symptoms appear.
    Notes to Physician:
         Treat symptomatically and supportively.

                 **** SECTION 5 - FIRE FIGHTING MEASURES ****

    General Information:
         Evacuate area and fight fire from a safe distance. 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. Dust can be an explosion hazard when
         exposed to heat or flame. This material in sufficient quantity and
         reduced particle size is capable of creating a dust explosion.
         Flammable solid. May burn rapidly with flare burning effect. May
         re-ignite after fire is extinguished.
    Extinguishing Media:
         Water spray may cause frothing. For large fires, use water spray,
         fog or regular foam. Contact professional fire-fighters immediately.
         For small fires, use dry chemical, carbon dioxide, sand, earth, water
         spray 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.
         Vacuum or sweep up material and place into a suitable disposal
         container. Clean up spills immediately, observing precautions in the
         Protective Equipment section. Scoop up with a nonsparking tool, then
         place into a suitable container for disposal. Avoid generating dusty
         conditions. Remove all sources of ignition. Provide ventilation.

                  **** SECTION 7 - HANDLING and STORAGE ****

         Wash thoroughly after handling. Remove contaminated clothing and
         wash before reuse. Minimize dust generation and accumulation. May
         form flammable dust-air mixtures. Avoid contact with eyes, skin, and
         clothing. Empty containers retain product residue, (liquid and/or
         vapor), and can be dangerous. Keep container tightly closed. Avoid
         contact with heat, sparks and flame. Use with adequate ventilation.
         Do not pressurize, cut, weld, braze, solder, drill, grind, or expose
         empty containers to heat, sparks or open flames.
         Keep away from heat, sparks, and flame. Keep away from sources of
         ignition. Store in a tightly closed container. Store in a cool, dry,
         well-ventilated area away from incompatible substances.


    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.
    Personal Protective Equipment

                      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.
                      Wear appropriate protective gloves to prevent skin
                      Wear appropriate protective clothing to prevent skin
                      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 a respirator's use.
