Clean laboratories can be divided into ordinary clean laboratories and biosafety laboratories, and the following is a simple understanding of the difference between the two.
The experiments carried out in the ordinary clean laboratory are not infectious, but the environment is required to have no adverse effect on the experiment itself, so the laboratory is not equipped with protective facilities, and the cleanliness must meet the experimental requirements, so the laboratory disinfection should be carried out.
Biosafety laboratory is a biological laboratory with first-level protection facilities that can achieve second-level protection. Biosafety laboratories are required for scientific experiments in the fields of microbiology, biomedicine, functional experiments and gene recombination. The core of the biosafety laboratory is safety, which is divided into P1, P2, P3 and P4 levels according to the degree of biological danger.
P1 (BSL-1) Laboratory:
It is suitable for microorganisms that do not cause serious disease in healthy adults.
Basic personal protection, such as wearing a lab coat, is enough.
No special safety equipment or facilities are required.
P2 (BSL-2) Laboratory:
Treat medium-risk microorganisms that can cause infection through contact with skin wounds, mucous membranes, or inhalation.
Staff are required to receive specialized training and use personal protective equipment, such as gloves and goggles.
Facilities such as sinks and biosafety cabinets are needed to reduce exposure risks.
P3 (BSL-3) Laboratory:
It is used to study microorganisms that can spread through aerosols and can cause serious or even fatal diseases.
Higher levels of personal protective equipment, including respiratory protection, are required.
The laboratory must be equipped with a negative pressure system, and the air can be discharged after efficient filtration; There should also be physical isolation measures such as double-door entrances.
P4 (BSL-4) Laboratory:
It's a top-level biosafety lab, designed to handle the most dangerous microbes.
These microorganisms are highly contagious and often have no effective treatment.
Workers should wear positive pressure protective clothing and be thoroughly disinfected before leaving the contaminated area.
The laboratory has been designed to the highest safety standards, including individual ventilation systems, multiple sealed doors and emergency showers.
