V. HEALTH HAZARD

ACUTE EFFECTS OF OVEREXPOSURE

Swallowing:      Ingestion of this material is not known to result in significant adverse health effects.

Skin Absorption: DNA

Inhalation:      Mist or spray may cause allergic reactions in susceptible individuals. Avoid breathing fumes.

Skin Contact:    This material is not known to be a skin irritant, but it is recommended that prolonged contact

                 with skin be avoided.

                      specialist. In case of inhalation, drink water. if symptoms occur, see a doctor.



VIII. SPECIAL PROTECTION INFORMATION

Ventilation:     Efficient exhaust ventilation should always be provided to draw fumes and vapors away from

                 workers to prevent routine inhalation. Ventilation should be adequate to maintain the ambient

                 workplace atmosphere below the TLV of any items identified under the hazardous

                 components section.

Respiratory

Protection:      Normal. Wear a MIOSH/MSHA approved respirator whenever exposure to fumes or vapors

                 exceeds the TLV of any items identified under hazardous components section.

Protective

Gloves:          Impervious gloves, such as Neoprene or polyvinyl alcohol, should be worn when handling

                 chemicals.

Eye Protection:  Goggles/Safety Glasses/Mono-goggles

Other Protective

Equipment:       Long Sleeve shirt/Rubber apron/Safety shoes



IX. SPECIAL PRECAUTIONS IN HANDLING AND STORING

Keep from freezing. Protect against physical damage. Store in a cool, dry area in closed containers. Segregate from

acids, peroxides and all combustible organic or easily oxidizable materials. Keep away from heat and flame. Avoid

accidental discharge into sewers and natural waters. Empty container retains vapor and product residue. Observe all

labeled safeguards until cleaned, reconditioned, or destroyed.
