If a few drops of acid fall on the skin, what should be done first?
Answer and explanation
Correct answer: Wash with plenty of water
The governing safety principle is immediate dilution and removal of the corrosive substance. The affected skin should be washed with a large amount of running water as soon as possible, which reduces the acid concentration and carries it away. Hence option A is correct. Applying a strong base is unsafe because neutralisation may release heat and cause another chemical injury. Rubbing can spread or damage the skin, and waiting allows the acid to penetrate further; medical help should be sought when needed.
