Abstract:
Based on the engineering practice, the sealed design of key nodes for high-level biosafety laboratories(BSL-3 and BSL-4 Laboratory) are introduced including the selection and assemblage of panel materials of building enclosure, a variety of channels through walls, and inflatable airtight doors and efficient exhaust filtration unit, which can solve the gastightness questions of building enclosure. The test results of model laboratory show that natural attenuation of the pres- sure is less than 250 Pa in 20 min when he indoor air pressure up to 500 Pa.
