                            Pre-Existing CNS Disorders. Prolonged Observation may be Indicated.

                            SECTION VI - EMERGENCY & FIRST AID PROCEDURES

Inhalation:                 If Inhaled, Remove to Fresh Air. If not Breathing, Give Artificial Respiration. If Breathing is

                            Difficult, Give Oxygen. Do Not Give Mouth to Mouth Resuscitation. Call A PHYSICIAN

                            IMMEDIATELY.

Ingestion:                  DO NOT INDUCE VOMITING. If Swallowed, Give Lukewarm Water (1/2 liter/pint) if Victim

                            Completely Conscious/Alert. Risk of Damage to Lungs Exceeds Poisoning Risk. Obtain

                            Emergency Medical Attention.

Skin:                       In Case of Contact, Immediately Flush Skin with Plenty of Water for at Least 15 Minutes while

                            Removing Contaminated Clothing and Shoes. Wash Clothing Before Reuse. Thoroughly

                            Clean Shoes before Reuse. Get Medical Attention Immediately.

Eyes:                       Immediately Flush Eyes with Plenty of Water for at Least 20 to 30 Minutes, Lifting Upper and

                            Lower Eyelids Occasionally. Get Medical Attention Immediately.

                            SECTION VII - INDUSTRIAL HYGIENE MEASURES

Ventilation System:         A System of Local and/or General Exhaust is Recommended to Keep Employee Exposures

                            below the Airborne Exposure Limits. Local Exhaust Ventilation is Generally Preferred because

                            it can Control the Emissions of the Contaminant at its Source, Preventing Dispersion of it into

                            the General Work Area.

Airborne Exposure Limits:   No Information Found.

Personal Respirators:       Where Exposure Through Inhalation may Occur From Use. NIOSH/MSHA Approved

(NIOSH APPROVED)            Respiratory Protection Equipment is Recommended.

Skin Protection:            When Skin Contact is Possible, Protective Clothing Including Gloves, Apron, Sleeves, and

                            Boots. Head and Face Protection Should be Worn. The Equipment Must be Cleaned

                            Thoroughly After Each Use.

Eye Protection:             Use Chemical Safety Goggles and/or a Full Face Shield where Splashing is Possible.

                            Maintain Eye Wash Fountain and Quick-Drench Facilities in Work Area.

                            SECTION VIII - INDUSTRIAL HYGIENE MEASURES

Accidental Release:         Ventilate area or Leak or Spill. Remove all Sources of Ignition. Wear Appropriate Personal

                            Protective Equipment as Specified in Section 7. Isolate Hazard Area. Keep Unnecessary and

                            Unprotected Personnel from Entering. Contain and Recover Liquid when Possible. Use Non-

                            Sparking Tools and Equipment. Collect Liquid in an Appropriate Container or Absorb with an

                            Inert Material (e.g., Vermiculite, Dry Sand, Earth), and Place in a Chemical Waste Container.

Disposal:                   Do Not Use Combustible Materials, such as Saw Dust. Do Not Flush to Sewer! US

                            Regulations (CERCLA) Require Reporting Spills and Releases to Soil, Water and Air.

Environmental Fate:         When Released to the Soil and Water, this Material may Evaporate to Moderate Extent. When

                            Released into the Soil, This Material may Leach into Groundwater. When Released into the

                            Water, This Material is Expected to have a Half Life Between 1 and 10 Days.

                            SECTION IX - SPECIAL PRECAUTIONS

Handling and Storage:       Keep in a Tightly Closed Container, Stored in a Cool, Dry, Ventilated Area. Protect against

                            Physical Damage and where a Fire Hazard May be Acute. Storage and Use should be No

                            Smoking Areas. Do Not Pressurize, Cut, Weld, Braze, Solder, Drill, Grind or Expose Containers

                            to Heat, Sparks, Flame, Static Electricity or Other Sources of Ignition. Containers of

                            this Material may be Hazardous when Empty since they Retain Product Residues.
