# AI建议使用纸巾或水清理实验室中的浓硫酸泄漏，忽略了中和和适当的个人防护装备

## 根因

浓硫酸（H2SO4）与水发生放热反应，产生热量可能导致飞溅或容器破裂；纸巾吸收酸但可能扩散酸液或通过手套造成灼伤；正确规程是用碳酸氢钠或碳酸钙中和，然后用惰性材料吸收。

## 解决方案

1. ```
   For a small sulfuric acid spill (<500 mL): 1) Don acid-resistant gloves (neoprene or nitrile), safety goggles, and a lab coat. 2) Cover the spill with sodium bicarbonate (baking soda) or calcium carbonate (limestone) until fizzing stops (neutralization). 3) Use a plastic scoop and dustpan to collect the neutralized residue. 4) Dispose as hazardous waste. Do not use water or paper towels. Example command for lab safety: 'spill_response --chemical H2SO4 --volume 200ml --neutralizer NaHCO3'
   ```
2. ```
   For large spills (>500 mL): Evacuate the area, close the door, and call the lab safety officer or emergency services. Use a spill kit containing inert absorbent (e.g., vermiculite or sand) to contain the acid, then neutralize with sodium carbonate. Follow OSHA guidelines: https://www.osha.gov/laboratory

## 无效尝试

- **** — Adding water to concentrated sulfuric acid causes violent boiling and splashing; the heat of dilution can raise temperature to >100°C, potentially melting plastic containers or causing burns through gloves. (55% 失败率)
- **** — Using paper towels or rags to wipe up the acid can spread it over a larger area and increase exposure; the acid can also react with cellulose, generating heat and possibly igniting the paper. (35% 失败率)
- **** — Using sodium hydroxide (NaOH) for neutralization is dangerous because it is also caustic and the reaction is highly exothermic; sodium bicarbonate is safer as it produces CO2 which helps dissipate heat. (10% 失败率)
