根因分析
中和反应会放热，可能加剧热损伤；正确的急救方法是立即用大量清水冲洗至少20分钟。
English
Neutralization reactions generate heat exothermically, which can worsen thermal injury; the correct first aid is immediate, copious irrigation with water for at least 20 minutes.

-
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.
-
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.
-
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
常见但无效的做法:
-
95% 失败
Vinegar (acetic acid) reacts with NaOH to produce sodium acetate, water, and significant heat, causing thermal burns on top of chemical injury.
-
90% 失败
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.
-
85% 失败
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.
