Overall Plan for Gas Safety Management in University Laboratories

A three-tier architecture combining portable, fixed, and chemical cabinet sniffing, integrating with laboratory access control and fume hoods

行业痛点

高校实验室气体风险类型多、空间分散、人员流动大、监管薄弱：① 储气钢瓶（H2 / CO / CH4 / O2 / 特种气体）泄漏风险 — 一座 985 高校化工 / 材料 / 生命学院往往有 200+ 只在用钢瓶；② 实验过程产生 HCl / Cl2 / NH3 / HCN / H2S 等剧毒蒸汽；③ 通风柜风速不达标 / 通风柜与气体探测脱节；④ 学生 / 研究生轮换频繁，安全培训覆盖不足；⑤ 教育部 + 应急管理局”双随机”检查严格，2024 年起《高等学校实验室安全分类分级管理办法》要求三级以上实验室必须接入安全监管平台。一次实验室爆炸 / 中毒事件（如 2021 年南京航空航天大学甲醛泄漏）会引发停工整顿 + 教学影响 + 学校声誉危机。

方案概述

优锐安针对高校实验室提供”储气源 + 通风柜 + 实验室空间 + 中央平台”四级监测方案：① **储气钢瓶间**：每瓶可燃气专用泄漏探头（H2 / CH4 / CO 等）+ 房间整体可燃气 + 助燃气（O2 浓度 > 23.5% 助燃风险）+ 视频联动；② **通风柜风速 + 风量监测**：超低风速（< 0.3 m/s）报警，与气体探头联动加大新风；③ **实验室空间**：分布式有毒气体探头（按实验类型选 HCl / Cl2 / NH3 / HCN / VOC），采用电化学 + PID 复合原理；④ **中央 EMS 平台**：全校全实验室气体 + 视频 + 通风状态实时上墙，对接教育部 / 应急管理局监管平台，自动生成日报 / 异常预警 / 人员定位。配套学生扫码进入 + 安全准入考试模块。

## Laboratory Classification and Distribution Strategy

– **Chemistry / Chemical Laboratory**: HCl + Cl2 + NH3 + VOC + Fume Hood Velocity
– **Life Sciences / Biochemical Laboratory**: H2S + HCN + Formaldehyde + CO2 (leakage from incubator)
– **Materials / Physics Laboratory**: H2 (thin film sputtering) + Ar (shielding gas, risk of oxygen deficiency) + He
– **Gas Chromatography / Mass Spectrometry (Analysis Platform)**: He + H2 + N2 + O2
– **Gas Storage Cylinder Room (Shared)**: Combustible LEL + Combustion Supporting O2 + Toxicity (selected based on actual gas type)
– **Fume hood (per hood)**: wind speed/air volume sensor, alarm for ultra-low wind speed < 0.3 m/s ## Key Technical Indicators - Range: H2 0-100% LEL (PPM-level sensitivity) / CO 0-500 ppm / Cl2 0-20 ppm (laboratory-grade accuracy) - Explosion-proof: Laboratory zones are classified according to GB 50058, with gas cylinder rooms typically designated as Zone 1 → Ex d IIC T4 - Communication: RS485 + Modbus, compatible with the school's existing EMS / smart campus platform - Calibration: Conducted every 6 months, with calibration certificates provided (essential for inspection by the Ministry of Education) ## Implementation Essentials 1. **Access Permit System**: Students swipe their smart card / scan the QR code to enter → The gas status of the room is automatically retrieved → The door can only be opened if the status is normal 2. **Emergency Interlock**: Combustible Gas > 25% LEL → Shut off the main gas valve in the room + Initiate emergency ventilation + Close the access control to prevent others from entering
3. **Data Archive**: Records of gas concentration and ventilation status in each laboratory must be retained for at least 3 years (for traceability inspection by the Ministry of Education)
4. **Correction and Traceability**: In the event of an anomaly, it will be automatically pushed to the supervisor’s mobile phone, the college safety officer, and the school security office at three levels
