Correct use of the clean bench
Correct use of the clean bench(I) Preparation before useBefore using the clean bench, we need to do a series of preparations. First, check the equipment status mark to ensure that the equipment is in good condition. Then, turn on the ultraviolet light 30 minutes before use to sterilize the work area, and use the powerful sterilization ability of ultraviolet light to effectively remove potential microorganisms. At the same time, start the purification wind 20 minutes before use and wipe the table clean to provide a clean environment for subsequent operations. You can also soak the gauze with cleaning solution and wipe the table carefully to further ensure the cleanliness of the table. In addition, wipe the surface of the tools and items to be used with alcohol cotton and disinfect them before placing them on the workbench to ensure that these items will not be contaminated. Finally, pull down the glass covers on both sides of the workbench, and pay attention to evenly apply force with both hands to ensure the sealing of the work area. (II) Start-up operation process When starting the machine, first turn on the lighting switch and turn off the ultraviolet light at the same time to avoid ultraviolet rays from causing harm to the human body. It should be noted that the operating area is a laminar flow area, so the working position should not hinder the normal flow of airflow, and the staff should avoid actions that can cause disturbance of airflow to prevent affecting the purification effect of the clean bench. At the same time, the operator should wear work clothes to reduce the risk of contamination brought by himself. (III) Cleaning after shutdown After the work is completed, the fan should be stopped first. Then, clean the work surface and wipe the clean work surface with 75% alcohol to remove residual pollutants. At the same time, the waste generated during the operation must be collected and disinfected to prevent environmental pollution. Finally, the machine and workplace must be cleaned to keep the entire working environment clean and hygienic. |
