Clean rooms have become a standard in many modern manufacturing facilities. Also known as clean workshops or controlled environments, these spaces are designed to maintain strict levels of cleanliness, temperature, humidity, and air pressure, regardless of external conditions. The primary goal is to remove airborne particles, harmful substances, and microorganisms from the air, ensuring that the environment remains suitable for sensitive operations. Everything from temperature control, airflow velocity, noise levels, vibration, lighting, and static electricity is carefully managed within specific limits to support safe and efficient work.
When working in a clean room, there are several important rules to follow. Before entering, personnel must greet the management team and complete basic training. Once inside, smoking, eating, and bringing in unauthorized items like chemicals or personal belongings are strictly prohibited. Loud noises, such as shouting or laughing, should be avoided. All individuals must wear the company’s designated anti-static clothing, shoes, and accessories. This includes wearing a dust-free cap, mask, gloves, and shoe covers. When putting on a mask, it should cover both the nose and mouth to prevent contamination of sensitive materials. It's also essential to ensure that hair is fully covered by the cap before putting on the dust-free clothing to avoid any issues with loose strands.
Proper attire is crucial. The dust-free cap must completely cover all hair, and the neck veil should hang over the shoulders. Once the workwear is on, it must remain in place—shoulders and necks cannot be exposed. The clothing should fit properly without being too tight or too short, and it should not be worn inside out. Shoe covers must be pulled up and secured under the pants to prevent contamination. When handling gloves, avoid touching the palms or fingertips directly with bare hands to prevent contamination from sodium ions. The glove cuffs should be tucked into the sleeves to create a barrier against pollutants.
After dressing, individuals must step on a dust-removing mat and wash their hands before entering the clean room. When leaving, all protective gear must be removed in the designated locker room, never in other areas, especially not in the clean room itself. Dust-free garments, shoe covers, and other equipment should be cleaned regularly and replaced when damaged. When removing the clothing, the process should be reversed—starting with the gloves, then the cap, and finally the clothes. After removal, the garments should be hung in the upper cabinet, while the shoe covers are placed underneath. No other items should be stored in the small cabinets of the changing room except for the required dust-free supplies.
Only approved items, such as paper and tools, may be brought into the clean room. All objects must be wiped down with a lint-free cloth before entry. Any equipment brought in must first be reported to the manager and thoroughly cleaned in the designated area. Only tested and approved instruments can be used, and in case of an emergency, proper procedures must be followed, such as shutting off water, electricity, or gas. Fire hazards must never be left unattended in the clean room to prevent accidents.
There are many more safety measures to consider in a clean room environment. Everyone must pay close attention to these rules, as even small mistakes can lead to serious consequences and significant losses. Before entering the clean room, it is essential to fully understand the guidelines to work confidently and efficiently. Following these protocols ensures a safe and productive working environment.
