Engineering Construction Standards for CDC Laboratories: Building a Solid Defense Line for Public Health

As Guangzhou Cleanroom Construction Co., Ltd., which is dedicated to the production of purification equipment, we deeply understand the crucial role of Centers for Disease Control and Prevention (CDC) laboratories in the field of public health. These laboratories undertake important tasks such as disease monitoring, pathogen detection, and scientific research. Their engineering construction standards are directly related to the accuracy of test results and public health safety. Below, we will introduce the key engineering construction standards for CDC laboratories in detail.

It is necessary to strictly divide the clean area, semi - contaminated area, and contaminated area. The clean area is used for storing reagents, office work, etc.; the semi - contaminated area serves as a buffer zone where personnel change their protective equipment; and the contaminated area is the core operation area for sample testing, pathogen cultivation, etc. Reasonable passageways and barriers are used to separate different areas to prevent cross - contamination.

The flow routes of personnel, samples, and items should be clearly planned. For example, the path of samples from receipt, transfer to testing should avoid crossing the regular walking routes of personnel to reduce the risk of contamination. At the same time, a special waste passage should be set up to ensure that contaminated waste can be transported out of the laboratory safely and in a timely manner.

Equip with advanced and precise detection equipment, such as PCR amplifiers, high - performance liquid chromatographs, etc., to meet the detection needs for various pathogens and pollutants. These devices need to be calibrated and maintained regularly to ensure the accuracy and repeatability of test results.

To ensure the cleanliness of the experimental environment, efficient purification equipment is essential. The high - efficiency air filters produced by our company can effectively filter dust, microorganisms, and other pollutants in the air. Combined with a reasonable ventilation system, the laboratory can meet the corresponding cleanliness requirements, such as the common Class 10,000 or Class 100,000 cleanliness levels. In addition, biosafety cabinets need to be equipped to provide a safe operating space for operators and prevent the spread of pathogens.

The temperature and humidity in the laboratory have a significant impact on experimental results. Generally, the temperature needs to be controlled between 20 - 26°C, and the humidity is maintained at 40% - 60%. By installing a professional temperature and humidity control system, the environmental parameters are monitored and adjusted in real - time to ensure the stability of experimental conditions.

To prevent the spread of polluted air, a reasonable pressure difference should be maintained between different areas. For example, the contaminated area maintains a negative pressure relative to the semi - contaminated area, and the semi - contaminated area maintains a negative pressure relative to the clean area. In this way, air can flow from the clean area to the contaminated area, avoiding the reverse spread of pollutants.

Adopt a safe and reliable electrical system, equipped with leakage protection devices, emergency lighting, etc. At the same time, the electrical lines are laid reasonably to avoid safety accidents caused by problems such as aging and short - circuit of the lines.

Laboratory staff need to be equipped with complete personal protective equipment, such as protective clothing, goggles, gloves, etc. In addition, the laboratory should formulate strict biosafety management systems, including sample management, waste disposal, etc., to effectively prevent biological hazards during the experimental process.

The high - standard construction of CDC laboratories is an important foundation for ensuring public health safety.
