Such labs cannot handle dangerous virus, bacteria and other pathogens.<br />After SARS, the Union health ministry approved NICD’s upgradation to BSL-3. The main difference from the previous set up is that a BSL-3 lab is kept under negative pressure so that the air inside the laboratory – contaminated with dangerous virus and germs – are not allowed to mix with outside air.<br />Moreover, entire waste from a BSL-3 laboratory is incinerated in autoclaves to ensure nothing is mixed with outside environment and an air exchange system maintains the temperature.<br />The doors in a BSL-3 facility are controlled by pressure gradient.
