Final answer:
NCM designated RL3 refers to biosafety containment level protocols for Non-Contained Microorganisms at Risk Level 3 which handle potentially lethal agents and require stringent safety measures.
Step-by-step explanation:
The designation of NCM as RL3 is related to biosafety levels which are assigned to containment facilities and the practices they must follow for work with various types of organisms. In this context, NCM likely refers to Non-Contained Microorganisms and RL3 to Risk Level 3. Risk Level 3 is assigned to facilities handling microorganisms that can cause serious or potentially lethal disease through inhalation, and thus requires specialized safety measures and containment procedures. Facilities designated as RL3 must adhere to strict laboratory protocols, including security measures to prevent unauthorized access and the implementation of safety equipment like biosafety cabinets, sealed windows, and special ventilation systems to protect lab personnel and the outside community.
