Respuesta :
BSL-1, BSL-2, BSL-3, and BSL-4 are the four biosafety levels, with BSL-4 being the greatest level of confinement. Animal research (ABSL), agricultural research (BSL-Ag), and other forms of research have extra requirements and designations.
What are biosafety levels?
BSL-1 to BSL-4 are the biosafety levels. Each biosafety level expands on the regulations of the previous level.
Regardless of biosafety level, every microbiology laboratory adheres to conventional microbiological protocols.
BSL-1, BSL-2, BSL-3, and BSL-4 are the four biosafety levels, with BSL-4 being the greatest (maximum) level of confinement.
Animal research (ABSL), agricultural research (BSL-Ag), and other forms of research have extra requirements and designations.
Thus, these are the four biosafety levels as per the asked question.
