How to Prevent Cross - Contamination of Drugs in Pharmaceutical Cleanrooms

During the drug production process, ensuring the quality and safety of drugs is of utmost importance. As a crucial place for drug production, preventing cross - contamination of drugs in pharmaceutical cleanrooms is one of the core tasks to guarantee drug quality. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. has rich experience in the construction and maintenance of pharmaceutical cleanrooms. Today, we will discuss in detail how to effectively prevent cross - contamination of drugs in pharmaceutical cleanrooms.

Pharmaceutical cleanrooms should clearly divide different functional areas according to the production process, such as raw material storage areas, production areas, intermediate product storage areas, packaging areas, etc. Each area should be relatively independent. By setting up physical isolation facilities such as walls and buffer rooms, the random flow of air, materials, and personnel between different areas can be prevented, thus reducing the risk of cross - contamination. For example, processes with high dust generation, such as pulverization and granulation, should be set up in separate rooms and equipped with effective dust - removal devices to avoid dust diffusion and contamination of drugs in other areas.

Strictly distinguish between the access passages for personnel and materials to avoid cross - flow during the movement of personnel and materials. The personnel passage should be equipped with changing rooms, hand - washing and disinfection rooms, etc., to ensure that personnel are fully purified and disinfected before entering the workshop. The material passage should be equipped with material transfer windows, buffer rooms, and other facilities to clean and disinfect the materials entering the workshop, preventing pollutants carried by the materials from entering the production area.

Regularly train workshop staff, and the training content includes Good Manufacturing Practice (GMP) for drug production, hygiene knowledge, operating procedures, etc. Enable employees to fully understand the hazards of cross - contamination and how to avoid cross - contamination in their work. For example, teach employees the correct hand - washing methods, the norms for wearing work clothes, and how to avoid contact between different drugs during operations.

Establish employee health files and conduct regular health checks on employees. Personnel suffering from infectious diseases, skin diseases, or other diseases that may affect drug quality are strictly prohibited from entering the workshop. At the same time, employees are required to report promptly and take corresponding measures if they feel unwell during work to prevent drug contamination due to employee health problems.

When receiving materials, strictly check whether the packaging of the materials is intact and whether the labels are clear and accurate. After the materials are inspected and accepted as qualified, store them according to the specified storage conditions. Different varieties and specifications of materials should be stored separately and clearly labeled. For volatile and easily contaminated materials, measures such as sealed storage should be taken to prevent them from contaminating other materials.

The transfer of materials in the workshop should follow the specified routes and procedures to avoid contamination of materials during the transfer process. When using materials, strictly follow the operating procedures, use materials specifically for their intended purposes, and avoid mixing materials of different drugs. For example, during the batching process, ensure the cleanliness and accuracy of weighing instruments to prevent residual materials from contaminating subsequent batches.

Formulate strict equipment cleaning procedures, clarify the methods, frequencies, and selection of cleaning agents for equipment cleaning. After each production is completed, clean the equipment in a timely manner to ensure that there is no material residue on the equipment surface. For difficult - to - clean parts, use special cleaning tools and methods for treatment. At the same time, inspect and verify the cleaned equipment to ensure that the equipment cleaning effect meets the requirements.

Regularly maintain and service the equipment to ensure its normal operation. During equipment maintenance, pay attention to preventing maintenance tools, spare parts, etc. from contaminating the equipment and drugs. For example, when replacing equipment parts, clean and disinfect the new parts to avoid introducing contaminants.

Install an efficient air purification system, such as a combination of primary - effect, medium - effect, and high - efficiency filters, to filter the air entering the workshop and remove dust particles, microorganisms, and other pollutants in the air. At the same time, regularly detect and maintain the air purification system to ensure its filtration efficiency and operating effect.

Regularly disinfect the workshop environment, which can be achieved by means of ultraviolet irradiation, chemical disinfectant spraying, etc. During the disinfection process, pay attention to the selection and use methods of disinfectants to ensure the disinfection effect while avoiding drug contamination caused by disinfectant residues.
