Question

why should you wear gloves, apron, and eye protection when working with battery acid?
battery acid can cause serious burns.
it helps keep your clothes clean.
your supervisor says you have to wear them.
protective clothing is not necessary with battery acid.

Explanation:

Battery acid is a strong acid (usually sulfuric acid in lead - acid batteries). Strong acids can cause severe chemical burns upon contact with skin, eyes, or clothing. Wearing gloves, apron, and eye protection is primarily for safety against these burns. Keeping clothes clean is a secondary (and less important) aspect. Just because a supervisor says so is not the fundamental reason (the fundamental reason is the chemical's properties). And protective clothing is definitely necessary as battery acid is hazardous.

Answer:

Battery acid can cause serious burns.
