According to industry cleaners, possibly a quarter of cleanrooms maintain a serious and thorough cleaning schedule for their cleanrooms, which leaves a almost three quarters of clean rooms open to contamination, possibly necessitating the replacement of filters, vents, equipment, or a reworking of the clean room itself, which could lead to costly downtime.
Clean rooms are designed to keep contaminating particles and microbes out of the workspace. They are sealed rooms that often feature HEPA filtering systems of various types that remove particles in the air. Staff are generally required to wear protective clothing, hoods, and goggles to prevent additional shedding and the tracking in of particles from outside.
But again, the key aspect of the filter process is that the system removes particles from the air. When these particles settle onto surfaces they are more difficult to remove and can lead to contamination of sensitive processes in the room. Protective clothing and air showers can remove a lot of contaminating matter, but particles can often be dragged inside regardless. That is why it is important to maintain a regular cleaning regime in the clean room.
Clean room cleaning often involves specialized materials such as treated brooms, mops, and rags that are either coated or non-shedding or both. They also involve heavy duty cleaning agents that should remove as much contamination as possible so that the filters can do the rest of the work.
Otherwise it can be very expensive to replace contaminated equipment, and the downtime generated by a lapse in work could be equally costly, not to mention compounding problems caused by stalled supply chains if involved. If you are running a complex operation, one inactive clean room environment could have major repercussions for your entire operation. So considering the costs involved with downtime and contamination, it really isn’t too expensive or troublesome to maintain a rigorous cleaning schedule for your clean room.
