Clean rooms are maintained in the electronics, pharmaceutical, medical device companies and other manufacturing industries which want hygienic surroundings. These rooms are considered and planned using strict systems & protocols and remain always clean by using clean room equipments.

1. Clean Rooms to Enable Better Scientific Research
A clean room is a room which is usually used for scientific research or manufacturing. This room is has a very low level of environmental pollutants and is dust-free. The airborne contaminants are eliminated in this room. These contaminants are generated by the process, people and equipments, and must be continually removed from the air in the clean room.
Clean rooms are found in the electronics, pharmaceutical, medical device industries and other manufacturing industries which need a clean environment. These rooms are planned and designed using strict methods and protocols. All sources of contamination should be controlled or eliminated from these rooms. The other parameters that need to be in specified limits in these rooms are air flow rates, pressurization, temperature, humidity and filtration.
The clean room must be maintained at the same standards that it was built in. Some of the clean room equipments that facilitate proper maintenance are the HEPA (High Efficiency Particulate Air) filter, clean room architecture, filtration mechanisms, cleaning equipments, clean room garments, etc. The HEPA filters help in filtering particles as small as 0.3 microns. The clean room architecture helps in designing a room which maintains laminar air flow. In addition to the HEPA filters other filtration mechanisms are also essential in effective contamination control of the clean room. The cleaning equipments are the most important element of the clean room. Decisions on the type of cleaning materials to be used, the frequency of cleaning and the time at which the clean room should be cleaned should be decided by the clean room management. The clean room garments vary from industry to industry and location to location.
Effect of Human Presence
The biggest cause of concern in the clean rooms is the presence of humans. Physical behavior like fast motion and body regenerative processes like skin flakes, oils, hair and perspiration can increase contamination. The rate of movement, coughing, sneezing, odors and work habits of people present in the room are major sources of contamination.
Practices to Maintain Cleanliness
Effective use of clean room products like cleaning and disinfecting solutions, clean room mops, vacuum cleaner, clean room wipers, mop bucket and wringers help in maintaining the cleanliness of the room. The room must be cleaned by vacuuming the floors and work surfaces. The trash and waste must be disposed off periodically. The doors, door frames and lockers should be cleaned using approved cleaning solution. All personal items of the staff should be stored in personal lockers outside the clean room. Eating, smoking and gum chewing is strictly prohibited. Only garments approved for clean room use should be worn. Cosmetic use is not permitted. Hand dryers which are equipped with HEPA filters are recommended for use in the clean room. Physically ill persons, especially with stomach and respiratory disorders, should not enter the room. All these practices help in maintaining the cleanliness of the clean room.
