                           EYE CONTACT: Flush with plenty of water for at 15�20 minutes; assure adequate flushing by

                                        separating eyelids with fingers. Get medical attention immediately.

                          SKIN CONTACT: Wash with water for 15�20 minutes. If no burns have occurred, use soap and

                                        water to cleanse skin.

                              INHALATION: Remove to fresh air. If breathing becomes difficult, give oxygen. If not

                                          breathing, give artificial respiration. If patient is cardiac arrest, administer

                                          CPR. Continue life support measures until medical assistance arrives.

                               INGESTION: Rinse mouth with water insuring rinse is not swallowed. Drink 2 glasses of
