  Small Spill                                                               
       Sweep up material for disposal or recovery.  Absorb liquid on        
       vermiculite, floor absorbent or other absorbent material.

       Persons not wearing protective equipment should be excluded from     
       area of spill until clean-up has been completed. Stop spill at       
       source, dike area of spill to prevent spreading, pump liquid to      
       salvage tank. Remaining liquid may be taken up on sand, clay,        
       earth, floor absorbent, or other absorbent material and shoveled     
       into containers.                                                     
  7.   HANDLING AND STORAGE                                                 
       Containers of this material may be hazardous when emptied.  Since    
       emptied containers retain product residues (vapor, liquid, and/or    
       solid), all hazard precautions given in the data sheet must be       
  8.   EXPOSURE CONTROLS/PERSONAL PROTECTION                                
  Eye Protection                                                            
       Chemical splash goggles in compliance with OSHA regulations are      
       advised; however, OSHA regulations also permit other type safety     
       glasses.  Consult your safety representative.                        
  Skin Protection                                                           
       Wear resistant gloves such as:  neoprene, nitrile rubber, Wear       
       normal work clothing covering arms and legs..                        
  Respiratory Protections                                                   
       Not required under normal conditions of use.  If workplace           
       exposure limit(s) of product or any component is exceeded (see       
       exposure guidelines), a NIOSH/MSHA approved air supplied             
       respirator is advised in absence of proper environmental control.    
       OSHA regulations also permit other NIOSH/MSHA respirators            
       (negative pressure type) under specified conditions (see your        
       industrial hygienist).  Engineering or administrative controls       
       should be implemented to reduce exposure.                            
  Engineering Controls                                                      
       Provide sufficient mechanical (general and/or local exhaust)         
       ventilation to maintain exposure below TLV(s).  Not required under   
       normal conditions of use.
