Door Interlock Operation Prohibitions (The most critical, directly disrupting the clean air pressure difference)<br \/>\nIt is strictly prohibited to open both the inner and outer doors simultaneously.<br \/>\nThe interlock device is designed to prevent both doors from opening at the same time. Once both doors are opened simultaneously, the positive pressure in the clean area will be lost, and dust and microorganisms from the outside will directly flow in, causing the entire clean room to be contaminated; if the interlock fails, it must be immediately stopped and repaired. It is forbidden to forcibly pry the door open or dismantle the interlock switch.<br \/>\nIt is prohibited to open one door while the other is not fully closed.<br \/>\nIf the door is not tightly fastened or there is a gap in the sealing strip, the pressure difference will continue to leak, equivalent to a partially open door causing contamination.<br \/>\nDo not lean against, collide with, or forcefully drop or smash the passage window door.<br \/>\nThis may cause the door frame to deform, the sealing strip to not be tightly pressed, and the electromagnetic lock to be damaged, resulting in permanent air leakage.<br \/>\nProhibit blocking or jamming the door body (using materials, cardboard boxes to block the door)<br \/>\nLong-term jamming will cause the sealing strip to permanently deform and lose its sealing effect.<br \/>\nII. Material Transfer Prohibitions<br \/>\nProhibit transferring personnel, large workpieces, equipment, carts, etc., with oversized items<br \/>\nOnly allow the transfer of small materials, tools, samples, etc. It is strictly prohibited for people to pass through the passage window.<br \/>\nMaterials must not fill the box, be close to the ultraviolet lamp tube, or block the air duct (for laminar flow models)<br \/>\nThe ultraviolet rays cannot fully cover, and the airflow short circuits, resulting in the failure of disinfection and self-purification.<br \/>\nMaterials with uncleaned and disinfected outer packaging must not be sent into the clean area<br \/>\nCardboard, foam, woven bags have a lot of dust, and should be removed from the outer area, wiped and disinfected before being placed back.<br \/>\nLeaking liquids, unsealed waste liquids, powder materials should be directly placed<br \/>\nLeaking liquids will corrode the stainless steel box and contaminate the sealing strip; powder materials will adhere to the high-efficiency filter, contaminating the clean area.<br \/>\nHot objects, open flames, hot workpieces should not be placed directly<br \/>\nHigh temperatures will accelerate the aging and cracking of the rubber sealing strip, shortening its service life.<br \/>\nProhibit transferring flammable, explosive, strongly corrosive, highly volatile toxic reagents<br \/>\nUltraviolet irradiation, in a sealed space, volatile gases are prone to accumulate, posing risks of fire, corrosion of the box, and poisoning of personnel.<br \/>\nPolluted, contaminated waste materials must not be directly opened the door after reverse transfer<br \/>\nCleaned-out contaminants from the clean area must be immediately closed the door, and it is not allowed to keep the door open for a long time.<br \/>\nIII. Ultraviolet Disinfection Usage Prohibitions<br \/>\nWhen the ultraviolet lamp is working, it is strictly prohibited to directly look at the lamp tube or extend hands\/skins into the box<br \/>\nUltraviolet rays can damage the cornea and burn the skin.<br \/>\nIt is not allowed to open the door to take materials before the prescribed disinfection time is completed<br \/>\nThe standard disinfection time for a sterile workshop is \u2265 15 minutes. Opening the door directly before completing the sterilization will bring in microorganisms.<br \/>\nDo not stack shielding materials on the ultraviolet lamp<br \/>\nThe shaded areas cannot be disinfected, resulting in contamination dead zones.<br \/>\nIV. Equipment Storage and Environmental Prohibitions<br \/>\nDo not stack materials or leave equipment idle for a long time in the passage window<br \/>\nThe box should remain empty, only temporarily placed during transfer, and long-term stacking will lead to dust growth and bacterial breeding.<br \/>\nDo not directly rinse the inside of the box, electrical control switches, electromagnetic locks with water<br \/>\nWater ingress into the circuit will short-circuit and burn out the interlock, ultraviolet lamp controller, and cause leakage hazards; cleaning should only be done by using a dust-free cloth dipped in disinfectant.<br \/>\nProhibit drilling, cutting, or\u79c1\u81ea modifying the passage window box or door frame<br \/>\nThis will damage the overall airtightness and structure\uff0c resulting in permanent air leakage.<br \/>\nDo not stack heavy objects on the top of the passage window or the door frame<br \/>\nThe box will deform\uff0c and the door gap will fail to seal.<br \/>\nV. Management and Operation Prohibitions<br \/>\nContinue to use the passage window when the interlock\uff0c ultraviolet lamp\uff0c or fan is faulty<br \/>\nThe faulty state cannot guarantee the isolation of cleanliness\uff0c and it is necessary to hang a sign to stop and repair.<br \/>\nMixing materials from different cleanliness levels without strong disinfection<br \/>\nTransfer materials from a high-cleanliness level to a low-cleanliness level is acceptable\uff0c but transfer materials from a low-cleanliness level to a high-cleanliness level must be completely disinfected\uff0c and the omission of disinfection steps is prohibited.<br \/>\nUse strong acid and strong alkali disinfectants for cleaning<br \/>\nThey will corrode the inner wall of the stainless steel box and accelerate the aging of the rubber sealing strip\uff0c and prefer 75% ethanol and diluted peracetic acid. Untrained personnel operate the transfer window at will and fail to transfer materials in accordance with the SOP procedures.<\/p>","protected":false},"excerpt":{"rendered":"<p>Passage Window Complete Usage Prohibitions (General for Cleanrooms, divided into four categories: operation, materials, equipment, and safety) I.
