# AI advises using a weak acid (vinegar) to neutralize an alkali chemical burn, or a weak base (baking soda) to neutralize an acid burn, ignoring the exothermic reaction and increased tissue damage

- **ID:** `safety/chemical-burn-neutralization-myth`
- **Domain:** safety
- **Category:** physical_safety
- **Error Code:** `CHEM-BURN-NEUT-004`
- **Verification:** ai_generated
- **Fix Rate:** 90%

## Root Cause

Chemical burns require immediate dilution with copious water, not neutralization; neutralization reactions generate heat that can worsen thermal injury, and the delay in treatment allows deeper penetration of the chemical into tissue

## Workarounds

1. **Immediately flush the affected area with large amounts of lukewarm running water for at least 20 minutes, removing contaminated clothing. Use a safety shower or hose if available. Do not apply any neutralizing agents.** (92% success)

2. **If the chemical is a dry powder (e.g., lime, sodium hydroxide), brush off the powder before flushing to avoid activating it with water, then flush thoroughly** (85% success)

## Dead Ends

- **Apply vinegar to an alkali burn to neutralize it** — User remembers chemistry class concept of acid-base neutralization and applies it directly to first aid without considering exothermic effects (85% fail)
- **Mix baking soda with water and apply to the burn area** — User reads online forum suggesting baking soda paste for acid burns, thinking it's safer than water (80% fail)
- **Use any available kitchen acid or base to neutralize the chemical** — User assumes neutralization is faster than dilution and will stop the burn immediately (75% fail)
