本标准规定了病原微生物实验室生物安全标识的规范设置、运行、维护与管理。
本标准适用于从事与病原微生物菌(毒)种、样本有关的研究、教学、检测、诊断、保藏及生物制品生产等相关活动的实验室。
Introduction
Analysis of the core content of the standard
| Logo type | Safety color | Main function | Typical application scenarios |
|---|---|---|---|
| Prohibition sign | Red | Stop dangerous behavior | Laboratory entrance, near high-pressure vessels |
| Warning sign | Yellow | Prompt potential hazards | Biohazard area, sharps storage |
| Instruction sign | Blue | Mandatory protective measures | Areas where protective equipment must be worn |
Key technical requirements
The standard strictly stipulates that the chromaticity performance of the sign should comply with the requirements of GB 2893:
- Red chromaticity coordinate range: x=0.660~0.735, y=0.250~0.340
- Yellow brightness factor ≥0.45
- Retroreflective materials must meet Type 1 or Type 2 optical properties
Key points for implementation management
Taking the biological safety cabinet work area as an example, the following must be set up at the same time:
- Warning sign (Beware of biological hazards)
- Instruction sign (Protective gloves must be worn)
- Prohibition sign (do not suck liquid with mouth)
Standard evolution background
This standard integrates ISO 7010 international standard and GB 2894 domestic requirements, and for the first time formulates a special sign system for the characteristics of pathogenic microorganism laboratories to solve the shortcomings of the original standard in biological hazard warning.
