Abstract
Biosafety Level 3 (BL-3) research facilities should maintain negative pressures to prevent the propagation of bioaerosols to the atmosphere and protect researchers and the surroundings from exposure to bioaerosols. Therefore, it is necessary to investigate the influence of smoke and heat on the pressure inside a BL-3 research facility during a fire. The aim of this study was to investigate how the internal pressure in a BL-3 research facility changes during a fire incident. The CFAST simulation results showed that the internal pressure in the laboratory facility rapidly increased at the onset of the fire and continued to increase until the neighboring door was opened. The findings emphasize the need to extinguish a fire at the early stage of the fire to safeguard BL-3 research facilities.
