A Biological Safety Level (BSL 1, 2, 3, or 4) is assigned to a biological lab as a safeguard to protect laboratory personnel, as well as the surrounding environment and community.
With research into potential treatments, therapies and vaccines for the SARS-CoV-2 virus (known widely as the COVID-19 Coronavirus) exploding across the globe, many institutions and laboratories are wondering whether their equipment and lab are considered safe to contain samples of the virus. As discussed in our previous blog on biosafety levels, airborne transmissible diseases like COVID-19 are typically categorized as Biosafety Level 3 (BSL-3). BSL-3 laboratories are almost always purpose-constructed containment laboratories, outfitted with specialized equipment and HVAC systems designed to ensure no airborne particles can exit the contained space.
