Why BSL-3 is perfect for the prevention of corona virus.

BSL-3 

Again building upon the two prior biosafety levels, a BSL-3 laboratory typically includes work on microbes that are either indigenous or exotic, and can cause serious or potentially lethal disease through inhalation. Examples of microbes worked with in a BSL-3 includes; yellow fever, West Nile virus, and the bacteria that causes tuberculosis,Corona virus.

The microbes are so serious that the work is often strictly controlled and registered with the appropriate government agencies. Laboratory personnel are also under medical surveillance and could receive immunizations for microbes they work with.

Laboratory practices

• Laboratorians are under medical surveillance and might receive immunizations for microbes they work with.
• Access to the laboratory is restricted and controlled at all times.

Safety equipment

• Appropriate PPE must be worn, and respirators might be required
• All work with microbes must be performed within an appropriate BSC

Facility construction

• A hands-free sink and eyewash are available near the exit.
• Exhaust air cannot be recirculated, and the laboratory must have sustained directional airflow by drawing air into the laboratory from clean areas towards potentially contaminated areas.
• Entrance to the lab is through two sets of self-closing and locking doors
  

Common requirements-

• Standard personal protective equipment must be worn, and respirators might be required
• Solid-front wraparound gowns, scrub suits or coveralls are often required
• All work with microbes must be performed within an appropriate BSC
• Access hands-free sink and eyewash are available near the exit
• Sustained directional airflow to draw air into the laboratory from clean areas towards potentially contaminated areas (Exhaust air cannot be re-circulated)
• A self closing set of locking doors with access away from general building corridors

Access to a BSL-3 laboratory is restricted and controlled at all times.
