Introduction of standard operating procedures for ultra-clean workbenches

1 Objective to establish the operation rules of super clean worktable 2 Scope of application: it is applicable to the operation of ultra clean worktable in microbial limit inspection room 3 Responsible person: QC inspectors 4 Content 4.1 It is strictly prohibited to store unnecessary articles in the ultra clean work area to keep the clean air flow pattern unchanged 4.2 measure the average wind speed of the working area once a month with an anemometer If it is found that it does not meet the technical standards, adjust the voltage regulator and change the input voltage of the fan to make the working platform in an ideal condition 4.3 before going to work, the cleaning workers must clean the environment around the workbench and purify the air 4.4 before entering the ultra clean work area, the operator must wear clothes, trousers, caps and gloves in the buffer room, and try to avoid the action that obviously disturbs the air flow pattern 4.5 when using the worktable, turn on the ultraviolet sterilization lamp 500 minutes in advance to deal with the microorganism accumulated on the surface of the worktable in the working area, turn off the sterilization lamp 300 minutes later, and start the air blower 4.6 after the completion of the work, clean the working table with 0.1% Bromogeramine, turn off the air blower, turn on the ultraviolet lamp for sterilization for 30min, and turn off the power supply after Zui Instructions for operation procedures of super clean working table: 1 Precautions before operation (1) it is strictly prohibited to store unnecessary articles in super clean working area to keep clean air flow pattern unchanged (2) For the newly installed or unused worktable for a long time, it is necessary to clean the worktable and surrounding ring mirror with an Ultra-static vacuum cleaner or a tool that does not produce fiber before use, and then sterilize it with the drug sterilization method or ultraviolet sterilization method (3) The operating temperature shall not exceed 60 ℃ 2 The main steps of operating the super clean working table are as follows: (1) put the required instruments, tools, bacterial bags, test tubes, etc into the super clean working table after sterilization (2) When using the worktable, start the machine 30 minutes in advance (press the power key), press the setting key to check the setting of relevant parameters and the working status of the equipment, press the UV light key to turn on the UV sterilization light, and deal with the microorganism accumulated on the surface area in the operation area When leaving the room where the ultra clean working table is located, turn on the UV lamp in the buffer room in turn for sterilization After sterilization, the instrument shall be shut down for 30 minutes to convert ozone into oxygen, so as to avoid the stimulation to the operator's body Then press the fluorescent key to turn on the fluorescent lamp and start the fan It can be operated (3) Personnel shall wear disposable masks, hats and medical latex gloves (4) Properly open the sliding door of the super clean workbench Do what you need During the whole test, the experimenter shall clean the working table with 75% alcohol, turn off the blower, turn on the UV lamp for sterilization for 15 minutes, and turn off the power supply after Zui (6) After use, fill in the use record 3 Problems that should be paid attention to when using and maintaining the super clean worktable (1) during the whole experiment, the experimental personnel should operate according to the sterile operation procedures (2) UV has a strong irritant effect on human skin and retina It should be noted that the UV lamp must be turned off when people enter the buffer room for the first level operation; the penetration of UV is very weak, and ordinary glass can be completely blocked, so it is not allowed to add a lampshade to the UV lamp The oxygen in the opening will generate ozone under the ultraviolet irradiation Ozone will stimulate the respiratory mucosa The test operation should be carried out after waiting for a period of time (3) If there is an alarm in HEPA, it means that the air filtration performance of the equipment has problems, and the operation shall be stopped in time, and the status of the equipment shall be reported for replacement or maintenance of the filter material Shanghai Sujing Industry Co., Ltd if you have any need, you can pass with us at any time Thank you very much for your support and look forward to cooperating with you Thank you & bestragard!
