In the case of a chemical burn to the skin, what is the first step you should take?

Answer Details

The first and most critical step when dealing with a chemical burn to the skin is to immediately flush the affected area with copious amounts of clean, running water. This serves two purposes: it physically washes the chemical off the skin, and it dilutes any remaining chemical to reduce further tissue damage. Flushing should continue for at least 20 minutes.

Attempting to neutralise the chemical with a neutralising agent is dangerous in a first aid setting. A neutralisation reaction can be exothermic (heat-releasing), which would cause additional thermal burns on top of the existing chemical injury. This approach requires expert knowledge of the specific chemical involved and is not appropriate as a first response.

Applying a cold compress does not remove the offending chemical from the skin, so it fails to address the root cause of the injury. Covering the burn with a bandage before thorough flushing would trap the chemical against the skin, prolonging exposure and worsening the burn.

Exam tip: For chemical burns, the universal first aid rule is dilution by flushing with water, not neutralisation.
