Performance test of positive pressure bio-protective suits for high-level biosafety laboratories

Evaluates the practical performance and user experience of the domestic and imported positive pressure bio-protective suits through the typical operation combining with the subjective feeling of the staff. Tests the pressure difference inside the suits, air tightness, noise level and quantity of air supply in the simulated working environment of a high-level biosafety laboratory. The results indicate that the domestic and imported positive pressure bio-protective suits have no significant differences in practical performance and user experience. Both the suits can meet the operation requirements and can be used for the staff protection of high-level biosafety laboratories, but have hearing obstacles in different degrees.
