The biosafety laboratory is an important part of the overall decoration project of the laboratory. It integrates building decoration, air conditioning, ventilation, purification, water supply and drainage, gas, electrical, fire protection and other majors. A scientific and reasonable biosafety positioning is an important preparation for design and construction. jobs. The biosafety laboratory is used for scientific research, or production of products related to pathogenicity, or third-party testing (reserved for development). The level of secondary biological hazard is medium, with effective prevention and methods, and it is suitable for healthy adults and Animals will not cause serious harm. Simple understanding: the second level is controllable.
Of course, the same biological hazard is not static over time. For example, the SARS virus was classified as level 4 biosafety when it spread that year, but it has effective preventable and controllable measures and has been classified into the scope of level 3 biosafety. .
Most of the biosafety laboratories in the society are P2 or lower. The ABSL-2-b2 category in P2 belongs to the medium hazard of animal biological safety, and it cannot be effectively isolated by safety isolation devices such as biological safety cabinets. Such laboratories should be cleaned according to the level of 8 (100 thousand) cleanliness, negative pressure, small Designed with 12 air changes. Other biosafety laboratories lower than ABSL-2-b2 have no mandatory requirements for cleanliness, and can be mechanically ventilated or open windows for natural ventilation.
