Clean room transfer window cleaning and maintenance methods
Clean room transfer window cleaning and maintenance methodsThe clean room transfer window is a kind of purification equipment, also called a transfer box. Its function is to transfer items from non-clean areas to clean areas, or between clean areas, so as to reduce the number of door openings in the clean area and reduce pollution in the clean area.In order to standardize the cleaning and maintenance operations of transfer windows in clean rooms and provide operating basis for staff, the following are the cleaning and maintenance operation methods for transfer windows that are applicable to all clean rooms. Pass-through window cleaning: 1. Cleaning and maintenance cycle of the transfer window: Carry out every day during the clearance process after production; if the transfer window has not been used for more than 3 days after cleaning and disinfection, it needs to be cleaned and disinfected again before use again. 2. Cleaning agent: Purified water and sterilized water can be used; disinfectant options include 0.1% chlormethionate, 0.51% 84 disinfectant, 35% phenol, 0.5% peracetic acid, and 0.05% chlormethionine ( Disinfectant), 75% ethanol solution, etc. These doses need to be prepared in accordance with cleaning agent and disinfectant management regulations. At the same time, the type of disinfectant needs to be changed every half month. 3. Cleaning Tools: Use a fiber-free rag and bucket for cleaning. Cleaning method: (1) Clean the transfer window on the side with lower cleanliness level first. (2) Use a rag to soak in purified water first, then wring it out, and wipe the four walls on the inside of the transfer window (including the air supply vent and return air vent), the outer frame and the handle. (3) Wash the rag in purified water, wring it out, soak it in the disinfectant for at least 3 minutes, then wring it out and wipe the above parts of the transfer window. (4) The outer door and handle of the transfer window must also be cleaned and disinfected in the same way. (5) Cleaning, disinfection and storage of cleaning tools need to be carried out in accordance with cleaning agent and disinfectant management regulations. (6) Inspection: After cleaning and disinfection are completed, the inspector will conduct an inspection. If the equipment passes the inspection, a "cleaned" status card will be affixed. If it is unqualified, it will be cleaned again by the staff on duty. Maintenance of delivery window: 1. The transfer window is a passage for items and cannot be used as a storage place for items. 2. After using the transfer window, the window should be closed immediately and the window should not be left open for too long. 3. When using the transfer window to transfer items, the capacity of the transfer window must not be exceeded each time to avoid squeezing the window and deforming it. 4. According to the "Standard Operating Procedures for Monitoring Ultraviolet Disinfection Effect", the disinfection effect of ultraviolet light needs to be tested regularly, and the ultraviolet radiation intensity is measured through the ultraviolet intensity test card to determine whether the ultraviolet lamp needs to be replaced. 5. If there is an abnormality in the transfer window, you should contact a professional for repair. The above is an introduction to the cleaning and maintenance methods of clean room delivery windows. I hope it will be helpful to everyone. The clean room transfer window is an important purification equipment to ensure the cleanliness of the clean room. Correct cleaning and maintenance habits of transfer windows are key factors in improving the service life of transfer windows. Regular cleaning and maintenance are required to avoid contamination and cross-contamination to ensure that the cleanliness of transfer windows meets standards. Only by strictly complying with relevant norms and standards can we achieve a high-quality clean room environment and ensure health and safety in production, scientific research, medical and other fields. |
