Introduction
Analysis of the core content of the standard
| Chapter | Core requirements | Key technical indicators |
|---|---|---|
| Laboratory classification | Divided into 7 functional areas | Net height of general/special laboratory area ≥2.6m |
| Safety protection | Independent storage of dangerous goods | Explosion-proof distance ≥1.5m, negative pressure ventilation |
| Ventilation system | Fume hoods are given priority | Surface wind speed 0.25-0.75m/s |
Key technical specifications
1. Laboratory space design
The standard unit combination design must meet the following requirements: span ≥ 2.8m, depth ≥ 6.0m, and the net distance between the central laboratory table and the side table ≥ 1.5m. The fume hood should avoid interference from the main airflow and be ≥ 1.2m away from doors and windows.
2. Safety protection system
- Dangerous chemical storage rooms must be equipped with 24h mechanical ventilation
- Areas using radioactive materials must be equipped with a protective shielding layer
- Emergency facilities: Eyewash station + spray device for every 100㎡
3. Mechanical and electrical system specifications
| System type | Requirements |
|---|---|
| Ventilation | Supplementary air volume ≥ 90% of exhaust air volume |
| Electrical | Laboratory grounding resistance ≤ 4Ω |
| Water supply and drainage | Corrosive sewage pipes use PPR material |
Implementation suggestions
- Preferably adopt modular design to reserve space for renovation
- Establish a three-level protection system: engineering control-management measures-personal protection
- Special laboratories require BIM pipeline integration pre-arrangement
