As an auxiliary equipment of clean room, the pass box is mainly used for the transfer of small items between clean area and clean area, between unclean area and clean area, so as to reduce the number of clean room door opening times and minimize the pollution of clean area . If the pass box is used without certain management regulations to regulate the use of the pass box, it will still pollute clean area. In order to further improve the usage safety of pass box, the following is a simple analysis for you.
①Because pass box is equipped with an interlocking device, the door of the pass box can only be opened and closed at the same time; when the material is from a lower cleanliness level to a higher cleanliness level, the cleaning work on the surface of the material should be done; check the ultraviolet radiation in pass box frequently. To check the working condition of the lamp, replace the UV lamp regularly.
② The pass box is managed according to the higher cleanliness level of the clean area connected to it, for example: the pass box connecting the workshop with class A+ to class A clean workshop should be managed according to the requirements of class A+ clean workshop. After get off work, the operator in clean area is responsible for wiping all the surfaces inside pass box and turning on the ultraviolet sterilizing lamp for 30 minutes. Do not put any materials or sundries in pass box.
③Because pass box is interlocked, when the door on one side cannot be opened smoothly, it is because the door on the other side is not closed properly. Do not forcefully open it, otherwise the interlock device will be damaged, and the interlock device of the pass box cannot be opened. When it is working normally, it should be repaired in time, otherwise the pass box cannot be used.
