Introduction
With the continuous development and application of science and technology, the demand for industrial cleanrooms in all walks of life is also increasing. In order to maintain product quality, ensure production safety and improve product competitiveness, industrial enterprises need to build cleanrooms. The editor will introduce the standard requirements of cleanrooms in detail from the aspects of level, design, equipment requirements, layout, construction, acceptance, precautions, etc.
1. Cleanroom site selection standards
The site selection of cleanrooms should consider many factors, mainly the following aspects:
(1). Environmental factors: The workshop should be away from pollution sources such as smoke, noise, electromagnetic radiation, etc. and have good natural ventilation conditions.
(2). Human factors: The workshop should be away from traffic roads, city centers, restaurants, toilets and other high-traffic and high-noise areas.
(3). Meteorological factors: The surrounding terrain, landforms, climate and other natural factors should be considered, and it should not be in dust and sandstorm areas.
(4). Water supply, power supply and gas supply conditions: Good basic conditions such as water supply, gas, power supply and telecommunications are required.
(5). Safety factors: The workshop must be located in a relatively safe area to avoid the influence of pollution sources and dangerous sources.
(6). Building area and height: The scale and height of the workshop should be moderate to improve ventilation effect and reduce the cost of advanced equipment.
2. Cleanroom design requirements
(1). Building structure requirements: The building structure of the cleanroom should have the characteristics of dustproof, leakproof and infiltration-proof to ensure that external pollutants cannot enter the workshop.
(2). Floor requirements: The floor should be flat, dust-free and easy to clean, and the material should be wear-resistant and anti-static.
(3). Wall and ceiling requirements: The wall and ceiling should be flat, dust-free and easy to clean, and the material should be wear-resistant and anti-static.
(4). Door and window requirements: The doors and windows of the clean room should be well sealed to prevent external air and pollutants from entering the workshop.
(5). Air conditioning system requirements: According to the level of the clean room, an appropriate air conditioning system should be selected to ensure the supply and circulation of clean air.
(6). Lighting system requirements: The lighting system should meet the lighting needs of the clean room while avoiding excessive heat and static electricity.
(7). Exhaust system requirements: The exhaust system should be able to effectively remove pollutants and exhaust gas in the workshop to ensure the circulation and cleanliness of the air in the workshop.
3. Requirements for clean workshop staff
(1). Training: All clean workshop staff should receive relevant clean workshop operation and cleaning training and understand the standard requirements and operating procedures of the clean workshop.
(2). Wear: The staff should wear personal protective equipment such as work clothes, gloves, masks, etc. that meet the clean workshop standards to avoid personnel contamination in clean workshop.
(3). Operating specifications: The staff should work in accordance with the operating procedures of the clean workshop to avoid excessive dust and pollutants.
4. Equipment requirements for clean workshops
(1). Equipment selection: Select equipment that meets the clean workshop standards to ensure that the equipment itself does not generate too much dust and pollutants.
(2). Equipment maintenance: Regularly maintain the equipment to ensure the normal operation and cleanliness requirements of the equipment.
(3). Equipment layout: Reasonably layout the equipment to ensure that the spacing and channels between the equipment meet the standard requirements of the clean workshop.
5. Principles of clean workshop layout
(1). The production workshop is the main component of the clean workshop and should be managed in a unified manner, and clean air should be output to the surrounding channels with low air pressure.
(2). The inspection area and the operation area should be separated and operations should not be carried out in the same area.
(3). The cleanliness levels of the inspection, operation and packaging areas should be different and decrease layer by layer.
(4). The clean workshop must have a certain disinfection interval to prevent cross contamination, and the disinfection room must use air filters of different cleanliness levels.
(5). Smoking and chewing gum are prohibited in the clean workshop to keep the workshop clean.
6. Cleaning requirements for clean workshops
(1). Regular cleaning: The clean workshop should be cleaned regularly to remove dust and pollutants in the workshop.
(2). Cleaning procedures: Develop cleaning procedures and clarify the cleaning methods, frequency and responsible persons.
(3). Cleaning records: Record the cleaning process and results to ensure the effectiveness and traceability of cleaning.
7. Cleanroom monitoring requirements
(1). Air quality monitoring: Regularly monitor the air quality in the cleanroom to ensure that the cleanliness requirements are met.
(2). Surface cleanliness monitoring: Regularly monitor the cleanliness of the surfaces in cleanroom to ensure that the cleanliness requirements are met.
(3). Monitoring records: Record the monitoring results to ensure the effectiveness and traceability of the monitoring.
8. Cleanroom acceptance requirements
(1). Acceptance standards: According to the level of cleanrooms, formulate corresponding acceptance standards.
(2). Acceptance procedures: Clarify the acceptance procedures and responsible persons to ensure the accuracy and traceability of the acceptance.
(3). Acceptance records: Record the acceptance process and results to ensure the effectiveness and traceability of the acceptance.
9. Cleanroom change management requirements
(1). Change application: For any change to cleanroom, a change application should be submitted and can only be implemented after approval.
(2). Change records: Record the change process and results to ensure the effectiveness and traceability of the change.
10. Precautions
(1). During the operation of the clean workshop, attention should be paid to the handling of emergencies such as power outages, air leaks, and water leaks at any time to ensure the normal operation of the production environment.
(2). Workshop operators should receive professional training, operating specifications, and operating manuals, strictly implement operating procedures and safe operating measures, and improve their operating skills and sense of responsibility.
(3). Regularly inspect and maintain clean workshop, record management data, and regularly check environmental indicators such as cleanliness, temperature, humidity, and pressure.
