VI    HEALTH HAZARD DATA                       EFFECTS OF OVEREXPOSURE AND PRIMARY ROUTES OF ENTRY



      Eyes:          Irritant; may be toxic.

      Skin:          Irritant; may be toxic.

      Ingestion:     May be poisonous.

      Inhalation:    Fumes may be toxic.

VII    EMERGENCY AND FIRST AID PROCEDURES



       Eyes:          Flush open eyes immediately with clean water; see Physician.

       Skin:          Remove contaminated clothing; wash with soap and water; consult physician.

       Ingestion:     Induce vomiting. Contact a Physician.

       Inhalation:    Remove to fresh air. Give oxygen if breathing becomes difficult. See Physician.





VIII   PRECAUTIONS FOR SAFE HANDLING AND USE



       Spills:        Ventilate area, cover with absorbent material (vermiculite or sawdust or sand), shovel into open

                      top containers and wash area with water and detergent.

       Disposal:      Dispose of or incinerate waste in accordance with Local, State, and Federal regulations.

       Handling:      Sensitive to humidity; close container tightly after use. Do not reseal empty container.

       Storage:       Store out of direct sunlight and in moderate temperature (40/ F to 100/ F) in sealed containers.

                      Polyols will absorb atmospheric moisture. Organometallics may hydrolyze in the presence of

                      water or oxygen, forming metal oxides which may be poisonous if ingested.





IX     CONTROL MEASURES



       General:       No special control measures at ambient conditions where work area is adequately ventilated.

                      When airborne concentrations exceed the Federal OSHA exposure standard (0.02 ppm TLV)

                      wear MSHA/NIOSH approved respirator.

       Ventilation:   As required to maintain work area below TLV.

       Respiratory:   None required.

       Eyes:          Glasses are recommended in case of accidental splashing.

       Skin:          Chemically resistant gloves.
