Effects of Overexposure Contact with skin has a defatting effect causing drying and irritation.  Inhalation of              
vapors of vapors may cause nausea, vomiting, lightheadedness or headache.  Inhalation of excessive                       
may cause depression, dizziness, confusion or collapse.  Chronic effects of over-exposure may include                    
kidney and/or liver damage.                                                                                                                                   

Emergency and First Aid Procedures
            Ingestion Do not induce vomiting.  If conscious, cautiously give warm water, then mineral oil                       
            followed by hot coffee or strong tea.                                                                                                          
            Inhalation   Remove to fresh air.  If not breathing give artificial respiration.  If breathing is difficult                 
            give oxygen.                                                                                                                                              
            Skin    Immediately flush skin with plenty of water for at least 15 minutes.                                                   
            Eye     Immediately flush eyes with plenty of water for at least 15 minutes.   Get medical help.
