Clean rooms, also known as clean workshops or controlled environments, are widely used in modern factories to maintain strict standards of cleanliness, temperature, humidity, and air pressure. These spaces are designed to eliminate airborne particles, harmful substances, bacteria, and other contaminants, ensuring a safe and stable working environment. Every aspect—temperature, cleanliness, air pressure, airflow velocity, noise levels, vibration, lighting, and static electricity—is carefully controlled within specific limits to support precision work and prevent contamination.
Before entering a clean room, all personnel must greet the management staff and complete basic training. Once inside, smoking, eating, and bringing in unauthorized chemicals or personal items are strictly prohibited. Loud noises, such as shouting or laughing, are not allowed. Employees must wear designated anti-static clothing, shoes, and personal items stored in assigned lockers. A proper uniform, including a dust-free cap, mask, gloves, and shoe covers, must be worn at all times. The mask should cover both the nose and mouth to prevent contamination of sensitive materials. Hair should be fully covered by the cap before putting on the dust-free suit to avoid discomfort and ensure cleanliness.
When wearing the dust-free cap, all hair must be completely hidden, and the cap’s veil should hang over the shoulders. The dust-free suit must fit properly, with no exposed skin, and should not be reversed. After wearing the suit, shoe covers must be pulled up and secured over the pants. When handling gloves, avoid touching the palm or fingertips directly to prevent contamination from sodium ions. The glove’s wrist should be tucked into the sleeve to isolate potential pollution sources.
Once all protective gear is properly worn, employees should step on a dust-removing mat to remove any particles before entering the clean room. All dust-free clothing must be removed in the designated locker room, never taken outside the clean area. Regular cleaning and replacement of damaged garments and shoe covers are essential for maintaining hygiene. When removing the clothing, the process should follow the reverse order of how it was put on. After removal, the dust-free clothes should be hung in the upper compartment of the locker, while shoe covers are placed underneath.
Only authorized items, such as dust-free clothing, should be kept in the small cabinet of the dressing room. No other personal belongings are allowed. Similarly, only approved papers and items can be brought into the clean room. All equipment and tools must be wiped clean before entering, and any new devices must be reported to the manager and cleaned thoroughly. Only tested and approved instruments may be used. In case of an emergency, follow established procedures, such as shutting off water, electricity, or gas supplies. Smoking or leaving open flames in the clean room is strictly forbidden to prevent accidents.
There are many more safety measures to follow in a clean room environment. It is crucial for everyone to pay close attention to these rules, as neglecting them can lead to serious consequences and significant losses. Before entering the clean room, make sure you understand all the precautions so you can work confidently, efficiently, and safely.
