About clean clothes
Thread Content
I wonder what equipment you all wear in the laboratory? We are all required to wear clean clothes here... We used to wear white coats, but now because we have to go out to take samples, it is not troublesome. Moreover, ordinary chemical analysis rooms should not have high requirements for cleanliness, right?
We wear white coats, what do clean clothes look like?
There are white coats, but if you don’t wear them, it’s inconvenient. Just wear the same work clothes as ordinary operators! It’s very awkward to wear a big coat when you go to the venue! It is still necessary to wear a white coat when doing acid-base experiments to prevent acids and bases from dripping on the skin!

Its function is to control particulate pollution. In order to achieve the specified cleanliness level, effectively control particulate pollution, and enable people to engage in precision production and scientific experiment activities, the clean room is by no means limited to "clean", but must be a multi-functional complex with considerable requirements for cold and heat, noise, illumination, static electricity, and micro-vibration. It is a product that integrates various professional technologies such as architectural decoration, purified air conditioning, pure water and pure gas, and electrical control.

If the analysis and testing requirements reach PPT level, the inspection personnel are required to wear clean clothes. It is recommended that analysts and sampling personnel be separated.
“What is the difference between "clean clothes" and "white coats"?
I feel that whether it is a white coat or clean clothes,* Laboratories don’t have many requirements for cleanliness, but you should keep it tidy!

They should not be dusty. They should use fibers that are difficult to cause fiber shedding and will not break when worn for a long time.； 2. It has a filtering effect, and human body dust should not spread outward through the fabric. ； 3. Poor conductor materials with anti-static properties ； 4. Materials that are comfortable to wear, easy to move, and not stuffy ； 5. Good durability. Because it needs to be washed and reused frequently, it should have the durability to be washed repeatedly. ； 6. It is not suitable for adhering to dust particles, has corrosion resistance, is easy to operate, does not wrinkle after cleaning, and does not require ironing.
You should choose pure cotton material and just pay attention to cleanliness at work (for us ordinary analysts). Nowadays, we are generally reducing staff to increase efficiency, and fixing positions and staffing. It is difficult to separate samples and make samples. We can only wear work clothes for convenience, and white coats are not used even if they are issued.
Our clean clothes are made of chemical fiber and are a two-piece set (clothes & trousers, with elastic cuffs and trouser legs)... It is a bit similar to dust-free clothes, but it is easy to generate static electricity, and the acid and alkali resistance is not very good. It is said that the leader of the next workshop thought that our white coats (the kind worn by doctors) affected the air cleanliness, so he reported to the superiors and asked us to change them.
Reply 5# pecker The clean clothes are a two-piece set, seemingly made of chemical fiber. The cuffs and trouser legs of the clothes and trousers are all elasticated. The white coat is the kind of pure cotton clothes doctors wear. Because only the top and lower work clothes and trousers are exposed, the leader of the workshop next to us thinks that it will bring in pollution (PS: Everyone in his workshop wears clean clothes, production workshop) {:3_60:}
