What first-aid procedure should be immediately administered if dilute acid splashes onto a student's skin in the science lab?
Answer and explanation
Correct answer: A. Flush the affected skin area immediately with plenty of clean running water for several minutes
- Step 1: Diluting and washing away the corrosive chemical is the primary first-aid priority. Step 2. Rinsing with abundant running water dissipates heat and removes the acid without causing secondary chemical burns. Answer: Flush the affected skin area immediately with plenty of clean running water for several minutes. Why not the others: Applying concentrated alkali causes an exothermic reaction and severe alkaline burns; oil and bandages trap the acid against tissue.
