       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, shovel into open top containers, wash area with

                      water and detergent.

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

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

                      open flames. Avoid eye and skin contact. Wash thoroughly after handling. Do not eat or smoke

                      while using.

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

                      Polyols will absorb atmospheric moisture.





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.

       Eyes:          Glasses in case of accidental splashing.

       Skin:          Rubber gloves and clean body-covering clothing.
