If a small amount of acid falls on the skin, what should be the first safe step in the laboratory?

Answer and explanation

Correct answer: Wash the affected area with plenty of water

The governing safety principle is immediate dilution and removal of a corrosive chemical. The affected skin should be washed at once with a large amount of running water, while contaminated clothing is removed if appropriate and laboratory supervision or medical help is sought. Water reduces the acid concentration and carries it away. Adding a strong base can cause another corrosive reaction and heat, rubbing spreads damage, and doing nothing is unsafe. Hence option A is correct.
