In modern scientific research and disease prevention, biosafety laboratories play a crucial role. Different laboratory levels, such as P1, P2, and P3, provide appropriate environments for various biological experiments, ensuring the safety of personnel, preventing pathogen leakage, and guaranteeing the accuracy and reliability of experimental results. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. offers an in-depth overview of the standards and requirements for these laboratories.
P1 laboratories have relatively simple layouts with no strict air-tight design requirements. Conventional building materials such as ceramic tiles, latex-painted walls, and terrazzo floors are commonly used. Surfaces should be smooth and easy to clean, preventing dust accumulation and facilitating daily maintenance.
Basic personal protective equipment (PPE), such as lab coats, gloves, and goggles, is provided to protect personnel from routine chemical reagents and non-pathogenic biological samples.
P1 labs are mainly used to study microorganisms that pose minimal risk to healthy adults, such as non-pathogenic E. coli strains. Standard laboratory procedures—like handwashing and proper disposal of waste—are sufficient for safety.
While strict isolation is not required, maintaining cleanliness and minimizing unnecessary items is recommended to ensure a safe working environment.
General ventilation is used to ensure continuous air renewal. The air change rate typically meets basic requirements ([X] times per hour), effectively exhausting minor odors and moisture while maintaining fresh indoor air.
Compared to P1, P2 labs have enhanced protection requirements. The building structure requires moderate air-tightness. Walls often use color-coated steel panels to block contaminated air, while interior materials are corrosion-resistant and easy to clean to prevent microbial growth.
A biosafety cabinet (e.g., Class II A2) is a core protective device, allowing safe handling of moderate-risk microbial samples while filtering exhaust air to protect both personnel and the environment.
P2 labs handle microorganisms with moderate hazards, such as influenza viruses. Personnel must undergo professional training, understand pathogen characteristics, and strictly follow standard operating procedures.
PPE, including protective clothing, masks, and double-layer gloves, is mandatory. Proper procedures for donning, doffing, and disinfecting equipment prevent contamination. Emergency protocols are in place for accidental spills or leaks.
P2 labs require complex ventilation systems. In addition to sufficient air changes ([X] times per hour), directional airflow ensures air moves from clean to contaminated areas. Supply and exhaust ducts are made from high-quality galvanized or stainless steel with smooth interiors to reduce resistance and prevent dust accumulation. Exhaust air is purified through high-efficiency filters.
P3 labs are highly air-tight, designed like a secure “fortress." Walls, ceilings, and floors are made of double-layer steel panels with insulating, soundproof, and air-tight materials to ensure maximum containment.
The entrance features a multi-level access control system permitting only authorized personnel. Advanced positive-pressure protective clothing is provided, and alarms notify staff of any breach to ensure safety.
P3 labs handle high-risk pathogens, such as the Ebola virus. Personnel must undergo extensive training and certification, and experiments strictly follow BSL-3 standards.
All procedures—from sample reception and storage to experimental operations and waste disposal—follow detailed guidelines. Experiments are recorded for traceability, and emergency response systems are in place for accidents.
P3 labs utilize top-level ventilation systems, including fresh-air-only designs, high air-change rates ([X] times per hour), redundant supply and exhaust units, and double filtration of exhaust air. Some systems even employ high-temperature disinfection to eliminate pathogen transmission risks.
P1, P2, and P3 laboratories have distinct standards and strict requirements, suitable for experiments with varying biological risk levels.
