# AI 建议用纸巾或水清理实验室中的浓硫酸泄漏，忽略中和和个人防护装备要求

## 根因

浓硫酸（H2SO4）是一种强脱水剂，与水发生放热反应（可能沸腾和飞溅）。纸巾吸收酸液，扩散并产生热量，可能引燃有机材料。正确规程：用碳酸氢钠（小苏打）或碳酸钙中和，然后用惰性材料（蛭石、沙子）吸收。必须穿戴PPE（耐酸手套、护目镜、实验服）。AI可能混淆弱酸泄漏（如乙酸）或一般清洁建议。

## 解决方案

1. ```
   Evacuate the area, ventilate, and don acid-resistant PPE (nitrile gloves, chemical splash goggles, lab coat). For small spills (<1 L), carefully cover with sodium bicarbonate (baking soda) until fizzing stops. Use a plastic scoop to transfer neutralized residue to a chemical waste container. For large spills, use a spill pillow or vermiculite to contain, then neutralize.
   ```
2. ```
   If sodium bicarbonate is unavailable, use calcium carbonate (limestone powder) or soda ash (sodium carbonate). For extremely concentrated acid (>95%), consider using sand or diatomaceous earth first to absorb, then neutralize the absorbed material. Never add water directly to the spill.
   ```

## 无效尝试

- **** — Water reacts with concentrated H2SO4 exothermically (temperature can exceed 100°C), causing splashing and potential burns. The heat can also damage lab surfaces or ignite nearby combustibles. (90% 失败率)
- **** — Universal absorbents may not neutralize acid; they only soak it up, leaving corrosive residue. Some pads are hydrophobic and won't absorb concentrated acid effectively. (70% 失败率)
- **** — Concentrated H2SO4 degrades latex rapidly (within seconds). Use nitrile or neoprene gloves; safety glasses do not protect against splashes (goggles required). (85% 失败率)
