                                       NaOH is an eye and mucous membrane irritant and severe skin irritant. The

                                       CB130 solution with a concentration of 0.05N NaOH will irritate skin, eyes,

                                 and mucous membranes. Carcinogen status: none.

                CHRONIC EFFECTS: Prolonged exposure may cause bronchial irritation, coughing, bronchial

                                       pneumonia, and gastrointestinal disturbances.

                       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.
