What to Do If Sulfuric Acid Touches the Skin

Accidental exposure to sulfuric acid is serious and requires immediate action. This strong corrosive chemical can cause severe burns on contact with skin or eyes, and time is critical when responding.

If sulfuric acid comes into contact with the skin, the first step is to remove any contaminated clothing carefully—without spreading the acid further. Then, immediately rinse the affected area under running water for at least 15 minutes. The goal is to flush away the chemical and minimize tissue damage. Do not delay this step, even if the burn seems minor at first. The same thorough rinsing applies if the acid gets into the eyes, though in such cases it’s especially important to keep flushing while seeking emergency help.

If the acid has been swallowed, giving water or milk right away may help dilute the chemical—but only if the person is conscious and able to swallow without difficulty. If they are vomiting, unconscious, or having trouble breathing, do not give anything by mouth. In all ingestion cases, call emergency services immediately.

Regardless of the type of exposure, medical attention is essential. Even if symptoms seem mild, internal or long-term damage can still occur. Contact a poison control center or go to the nearest emergency room without delay. Quick, informed action can make a significant difference in recovery.
