## 解决方案

1. ```
   Immediately flush the affected area with copious amounts of cool running water for at least 20 minutes. Remove contaminated clothing while flushing. Use a safety shower if available.
   ```
2. ```
   For dry chemical (e.g., lime, sodium metal), brush off the chemical with a dry, non-abrasive tool before flushing, then irrigate with water for 20 minutes.
   ```
3. ```
   After irrigation, cover the burn loosely with a sterile non-stick dressing or clean cloth. Seek emergency medical evaluation for all chemical burns larger than 3 inches or on face, hands, feet, or genitals.
   ```

## 无效尝试

- **** — Vinegar (acetic acid) reacts with NaOH to produce sodium acetate, water, and significant heat, causing thermal burns on top of chemical injury. (95% 失败率)
- **** — Baking soda (sodium bicarbonate) reacts with strong acids to produce CO2 gas and heat; the foaming action can spread the acid and the heat worsens tissue damage. (90% 失败率)
- **** — Wiping can spread the chemical to unaffected skin and push it deeper into tissues; dry cloth may not remove all chemical and causes friction damage. (85% 失败率)
