Ed, This is actually a common incident in General Chemistry labs. Irrigating the exposure for 15 minutes is the only thing to do. The student can wash it with soap and water in the rest room after the 15 minutes. The health center doctor or emergency room doctor would not do anything different. The skin redness will go away in a few days. You should not add an acid to a hydroxide exposure. Cynthia A.
