In industries such as medical, electronics, food and precision manufacturing, Cleanroom Environments are important places to safeguard product quality and production safety. In order to ensure that the cleanliness of the cleanroom environment is not compromised, personnel need to follow a series of strict specifications when entering. This is not only responsible for the product, but also for the entire production process and the health of our customers.
In Cleanroom management, the ISO Cleanroom standard is a globally accepted standard for classifying cleanliness. According to ISO 14644-1, Cleanrooms are classified according to the number of particles per unit volume of air, ranging from ISO 1 to ISO 9. The lower the class, the fewer the particles in the air and the higher the cleanliness. When designing and managing cleanrooms, enterprises should determine the cleanliness level that meets the requirements of their products according to the actual production needs, and strictly implement relevant management measures.
In order not to affect the stability of the cleanroom environment, the staff usually need to follow the following steps before entering:
1. Replacement of special clean clothes: Before entering the clean area, it is necessary to take off daily clothes and put on dust-free clothes, dust-free shoes, masks and gloves that meet the requirements of cleanliness level.
2. Wash hands and disinfect: Use special hand sanitiser and hand dryer for clean room to clean hands thoroughly and reduce bacteria and particles to be carried.
3. Pass through the Air Shower: Before entering the clean area, personnel need to pass through the Air Shower, using high-speed clean airflow to effectively remove the dust and particles attached to the surface of the clothing, to prevent contamination from being brought into the clean environment.
Air Shower is the first line of defence for cleanroom personnel entering and leaving the control area. Through high efficiency filtration and high speed airflow, it instantly removes residual dust from the surface of the human body and ensures that the cleanliness of the air in Cleanroom Environments is up to standard. A high quality air shower room can effectively improve cleanroom operation efficiency and reduce the impact of personnel activities on cleanliness, and is an indispensable supporting equipment for ISO Cleanroom Environments.
After entering the cleanroom, personnel also need to comply with the following management requirements:
Move gently and avoid large movements to reduce particle dispersion.
Prohibit the carrying of unrelated items, including mobile phones, keys, jewellery, etc., to prevent particle contamination.
Wear neat and standardised clothing to ensure that dust-free clothing, masks and gloves are not torn and clothing is not exposed.
Walk according to the specified route, do not walk around, open and close doors and windows to reduce the fluctuation of Cleanroom Environment.
In addition to regulating the behaviour of personnel, cleanrooms also need to regularly test air cleanliness, temperature and humidity, differential pressure and other indicators to ensure that they continue to meet the requirements of ISO Cleanroom standards. At the same time, regular maintenance of Air Shower equipment, air-conditioning purification systems and high-efficiency filters, and timely cleaning of the ground and the surface of the equipment, in order to ensure that the cleanroom is in a long-term efficient and stable state.
