Most Bio-Safety Class 3 laboratories (BSL3) are more than halfway through their expected lifecycles, especially with regard to their building systems infrastructure (mechanical, electrical, lighting, plumbing). With age come concerns of reliability and questions about how the facilities compare to a 2015 state-of-the-art laboratory. For facility managers responsible for BSL3s, it’s the right time to assess their facilities and make any course corrections needed to keep users safe, and their data reliable and secure.
