                          RTECS #: TT2100000

                      RTECS NAME: Potassium hydroxide

                         REVIEWS: Only selected Registry of Toxic Effects of Chemical Substances (RTECS)

                                   data for crystalline KOH (pure) are presented here; K130 is 0.10N KOH.

                                   Refer to actual entry in RTECS for complete information.



                                Section V � Health Hazards and First Aid



                  ACUTE EFFECTS: For crystalline KOH: Orl-rat LD50: 365 mg/kg; may be fatal if inhaled,

                                 swallowed, or absorbed through skin. Depending on the intensity and

                                 duration of exposure, effects may vary from mild irritation to severe

                                 destruction of tissue. The K130 solution with a concentration of 0.005N KOH

                                 will irritate skin, eyes, mucous membranes, and upper respiratory tract; it

                                 can also be corrosive and causes burns.

                CHRONIC EFFECTS: Not established

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

                                 by separating eyelids with fingers. Get medical attention.

                     SKIN CONTACT: Rinse with 1% acetic acid (or vinegar) to neutralize, followed with plenty of

                                   water while removing contaminated clothing and shoes. Wash contaminated

                                   clothing before reuse. For chemical burns, apply sterile bandage securely,

                                   but not too tightly. Get medical attention.

                        INGESTION: Give water freely and/or 1% acetic acid (or vinegar), followed by milk. Do not

                                   induce vomiting. Get medical attention immediately.

                                  diluted acetic acid. Soak up spill with rags, paper towels, sponge; rinse away

                                  or discard. Clean spill-area thoroughly with water.

                  WASTE DISPOSAL: This solution may be sent to an EPA-approved waste disposal facility.
