The construction of a clean room is divided into many purification levels, so what is the difference between a 10,000-level clean room and a 100,000-level clean room? What is the difference between 10,000-class and 100,000-class dust-free workshops? What are the design and construction specifications for clean room purification engineering? Next, the editor of sz-pharma will introduce to you. The difference between the 10,000-level and 100,000-level clean room is mainly in several aspects: 1) Space: The level required by the clean room is the main factor determining the layout of the area. 2) Different levels of dust-free workshops require different temperature and humidity. Cleanliness is the key to choosing the number of air changes. The higher the cleanliness, the greater the number of air changes. The volume of high-efficiency tuyere at the end of the pipe also increases, and the factors controlling temperature and humidity, the higher the temperature and humidity control requirements, the more complete the supporting pharma machinery required, and the higher the cost. 3) The level requirements of the clean room are different, the illumination is different, and the number of lamps required is different. The difference between 10,000-level and 100,000-level is not limited to the above major aspects. From the above aspects, it can be seen that the difference in level makes the cost different. The higher the level, the higher the cost. The air cleanliness level in clean rooms and related controlled environments is divided according to the concentration of suspended particles in the air, that is, the maximum allowable number of particles per cubic meter of air is used to determine the air cleanliness level. 1. Several levels of clean pharmaceutical cleanroom: refers to the clean level, which can be understood as a clean room, but the clean room also needs to be ventilated. The air that is replaced needs to be purified by the clean room and then sent to the clean room. (100,000) level requires 15-19 air changes per hour, and the air purification time after complete ventilation does not exceed 40 minutes. 2. Purification parameters of 100,000-class, 10,000-class and 100-class clean workshops: ventilation times: 100,000 class ≥ 15 times; 10,000 class ≥ 20 times; 1000 ≥ 30 times; 100 ≥ 500 times. Adjacent room ≥5Pa Most of the workshops with the lowest requirements today use 100,000-level purification workshops; while 300,000-level purification sedimentation bacteria (cfu&#47, 100,000-level purification sedimentation bacteria (cfu/dish) is 10: 100,000-level ventilation parameters are ≥15 times&#47. Each cleanliness level has its own purpose, and the difference in purification is understood from the dust particles in the air; that is, the more air changes, the better. The design and planning of the purification project of the clean room need to be carried out in strict accordance with the industry standards: 1. Purification engineering design requirements 1. The purification engineering design must be strictly implemented in accordance with the relevant national policies and guidelines, so as to achieve scientific design, quality assurance, safety and application, and economy. energy and environmental protection requirements. 2. When using the original building for clean technology transformation, the design of the purification project must be based on the requirements of the production process, adjust measures to local conditions, treat them differently, and make full use of the existing technical facilities. 3. Purification engineering design should create necessary conditions for construction and installation, maintenance management, testing and safe operation. 4. The design of purification engineering should not only be carried out in accordance with this specification, but also comply with the relevant requirements of current international standards and specifications. Second, purification engineering grade 1, air cleanliness should be divided into five grades according to regulations. Class 10, Class 100, Class 1000, Class 10,000, Class 100,000 Note: For the calculation of dust particles greater than or equal to 5 microns in the purification project with air cleanliness of Class 100, multiple sampling should be performed. The test value can be considered reliable only when it appears multiple times. 2. The inspection of the air cleanliness level of the purification project should be based on the number of dust particles tested under dynamic conditions. The air cleanliness test of the purification project shall comply with the provisions of Appendix II. 3. The overall design of the purification project The selection of the location of the purification project and the general layout of the purification project should be determined according to the following requirements and after the comparison of the technical and economic plans: 1. It should be in an area with a low atmospheric dust concentration and a better natural environment; 2. It should be kept away from railways, wharfs, airports, traffic arteries, and factories, storage silos, storage yards and other areas with severe air pollution, vibration or noise interference that emit a large amount of dust and harmful gases. If it cannot be far away from serious air pollution sources, it should be located on the upwind side of the maximum frequency wind, or the leeward side of the minimum frequency wind throughout the year; 3. It should be arranged in a clean environment in the factory area, and the flow of people and goods does not pass through or rarely passes through. 4. For the location selection of the purification project with both micro-vibration control requirements, the vibration influence of the existing vibration sources around it should be actually measured, and it should be analyzed and compared with the allowable environmental vibration value of precision pharma machinery and precision instruments. 5. The maximum frequency wind direction in the purification project. When there is a chimney on the windward side, the horizontal distance between the purification project and the chimney should not be less than 12 times the height of the chimney. 6. The distance between the purification project and the main traffic road should not be less than 50 meters. 7. A ring-shaped fire lane (traffic road can be used) should be set up around the purification project. In case of difficulty, a fire lane can be set up along the two long sides of the factory building. 8. The road surface layer around the purification project should be made of materials with good integrity and less dust. 9. Greening should be carried out around the purification project. Lawns can be planted, trees that do not have harmful effects on atmospheric dust-laden agriculture can be planted, and greening communities can be formed. However, the fire fighting operation shall not be hindered.

How Comfortable Are Suits to Wear?

Anyone who's ever worn a cleanroom suit knows that while they're necessary for certain types of work, they can be quite uncomfortable. It's not uncommon to feel hot, stuffy, and restricted in movement when you're wearing one. So just how comfortable are cleanroom suits to wear? In this article, we'll explore the different factors that affect the comfort of cleanroom suits, and what can be done to make them more comfortable.

What Are Suits?

Before delving into the comfort level of cleanroom suits, it's essential to understand what they are. suits, also called cleanroom garments or protective clothing, are specialized clothing worn by workers in cleanrooms or controlled environments. Cleanrooms are highly sterile environments, such as those found in the medical, semiconductor, or pharmaceutical industry. The goal is to prevent contaminants, such as dust or microorganisms, from entering the pharma clean room by using special clothing and protocols.

The Different Types of Suits

There are different types of cleanroom suits, ranging from full-body suits to less restrictive clothing. The most common types of cleanroom suits are:

1. Coveralls: Made from lightweight, non-woven materials, coveralls offer the highest level of protection against contaminants. They're worn over regular clothing and have elastic bands at the wrists and ankles. They're designed to cover the entire body to minimize the risk of contamination.

2. Gowns: Gowns are similar to coveralls, except they're worn over regular clothing and cover only the upper body. They're primarily used in low-risk cleanrooms or for short durations.

3. Lab coats: Lab coats are lightweight and breathable, providing minimal protection against contaminants. They're often used in cleanrooms where the risk of contamination is low.

4. Booties: Booties are disposable shoe covers worn over regular shoes to prevent the transfer of contaminants from footwear.

Factors Affecting Suit Comfort

Several factors affect the comfort level of cleanroom suits, including the type of material, fit, and ventilation. Here are the main factors that impact the comfort of cleanroom suits:

1. Material: The material of the suit is perhaps the most crucial factor that affects comfort. suits can be made from various materials, including polyester, polypropylene, and Tyvek. The type of material used affects the suit's breathability, durability, and softness.

2. Fit: The fit of the suit is another critical factor that affects comfort. A suit that's too loose or too tight can be uncomfortable and restrict movement.

3. Ventilation: Ventilation is essential to reduce the heat and humidity that build-up inside cleanroom suits. If the suit doesn't have proper ventilation, the individual wearing it can become hot, sweaty, and uncomfortable.

4. Duration of Use: The longer the individual wears a cleanroom suit, the more uncomfortable it can become. Extended periods of time in a suit can cause individuals to become hot, sweaty, and fatigued.

5. Ease of Movement: The ease of movement is another factor that affects the comfort level of cleanroom suits. Suits that restrict movement can be uncomfortable and make it difficult to perform tasks.

How to Improve the Comfort of Suits?

suits are essential to maintaining the cleanliness of controlled environments, but they don't have to be uncomfortable. Here are a few ways to improve the comfort level of cleanroom suits:

1. Choose the Right Material: The right material makes all the difference in comfort. When choosing a cleanroom suit, opt for lightweight, breathable materials such as micro-porous fabric.

2. Proper Fit: The suit should fit well and not be too loose or too tight. An ill-fitting suit can restrict movement and cause discomfort.

3. Ventilation: Proper ventilation is crucial to maintaining adequate airflow. Suits with ventilation ports, mesh areas, or breathable fabric can help reduce heat and humidity inside the suit.

4. Quality of Suit: Invest in high-quality cleanroom suits that are designed to withstand extended periods of use. Cheaper suits may wear out or tear faster, causing discomfort.

5. Regular Breaks: When possible, take regular breaks from wearing the suit. This allows the individual to cool down, stretch, and take a break from the restrictive clothing.

Final Thoughts

suits are necessary for workers in cleanrooms or controlled environments, but they don't have to be uncomfortable. By choosing the right materials, ensuring proper fit and ventilation, investing in quality suits, and taking regular breaks, the comfort level of wearing a cleanroom suit can be improved.

Do Masks Filter the Same Particles as Surgical Masks?

When it comes to protecting yourself and others from harmful particles in the air, masks have become the go-to solution. With the COVID-19 pandemic, the use of masks has become ubiquitous, and as more and more people look to purchase masks, questions arise regarding efficacy. One common query is whether cleanroom masks filter the same particles as surgical masks. In this article, we'll dive into the specifics of pharma clean room masks and surgical masks, discussing the differences between the two and exploring which one may be better suited to your needs.

What Are Masks?

masks are designed to regulate the air quality in cleanrooms. A pharma clean room is a medical or scientific environment that requires a high level of cleanliness to prevent the contamination of products or experiments. The cleanliness of a cleanroom is measured in standards known as ISO classes. ISO 1 is the cleanest, with the least amount of contaminants, while ISO 9 is the dirtiest, with the most. masks are created with the intention of providing workers in these environments with a sterile and clean breathing experience. They are worn in combination with disposable clothing, hair covers, shoe covers, and gloves to minimize the amount of contaminants being introduced into cleanroom environments.

What are Surgical Masks?

Surgical masks are designed to protect the wearer from large droplets, splashes, and sprays of bodily fluids or other hazardous fluids. Typically used in medical settings, surgical masks are lightweight, disposable, and loose-fitting. They are not designed to filter out small particles suspended in the air but rather act as a barrier to keep the wearer's fluids from being transmitted to others.

Differences between Masks and Surgical Masks

One of the main differences between these two types of masks is their level of filtration. While cleanroom masks have a high level of particle filtration due to their ISO class specifications, surgical masks are designed for protection against bodily fluids and large droplets. masks are commonly rated as N95 or equivalent (such as P2, FFP2, KN95), which highlights their ability to filter out particulate matter between 0.1-0.3 microns in size. In contrast, surgical masks are not specifically rated, but they are known to provide minimal protection against small particles suspended in the air.

Another primary difference between cleanroom masks and surgical masks is their intended use. masks are meant to be used in sterile environments with a high level of cleanliness, whereas surgical masks are meant to be used in messy or unclean environments, where there is a high chance of being exposed to bodily fluids or splashes. Therefore, the level of filtration needed between the two is different, and so are the materials used to create them. masks are made from higher-quality, more robust materials than surgical masks to ensure their integrity in cleanroom environments, whereas surgical masks are made from lightweight, inexpensive materials.

Which Mask Is Better Suited to Your Needs?

When choosing which mask to purchase, consider the environment in which you'll be wearing it. If you work in a cleanroom environment or require high-level particle filtration, a cleanroom mask is your best bet. If you are in a medical setting, such as a hospital or a doctor's office, or if you are interacting with someone who could present a danger to you in terms of exposure to potentially harmful bodily fluids, a surgical mask may be more appropriate. However, both cleanroom masks and surgical masks can play an essential role in protecting ourselves and others from the spread of harmful particles, and it is important to select the right mask for your specific situation.

The Bottom Line

masks and surgical masks serve different purposes and are used in different types of environments. masks are designed for high-level particle filtration, while surgical masks are designed to protect against bodily fluids and large droplets. Both masks can play an essential role in protecting ourselves and others, and it is important to select the mask that fits your specific environment and needs. So, whether you're working in a cleanroom or encountering potentially hazardous substances, choosing the correct mask can make all the difference.
