As the title suggests: Many people ask whether it is still necessary to wear PPE and undergo medical check-ups when the concentration of occupational hazards at the work site is below the **limit value. Share your opinion and see what evidence there is!
There is no specific statement at the moment! But it is said that GBZ1 will be revised, and provisions in this regard will be added.
Below, it may not be suitable. However, there are organic substances that have odors, as well as dusts that may cause discomfort (though not pathologically), all of which can make employees feel unwell; in such cases, appropriate PPE should be provided. There are certain teratogenic and carcinogenic substances; now, protective equipment is required when the exposure level reaches half of the TWA. The list can be found in the \"Specifications for Personal Protective Equipment\" issued at the end of 2015. Furthermore, do you really guarantee that those tests were conducted under the \"worst possible environmental conditions\" in the \"environments where contact might occur\"? Is there no deviation, hehe:(
In fact, whether to wear it or not depends on the individual; if the level of hazard is below the specified limit, it is theoretically safe not to wear it. However, the following situations cannot be ruled out: 1. Everyone is different, and the same concentration can have varying effects on different people； 2. It is possible that **temporary conditions mean that the extent of certain hazards associated with harmful substances is not always clear ； The limits set now may not be appropriate ； 3. There may be some harmful factors of certain substances that have not been recognized ； 4. It is not excluded that certain harmful substances, which our bodies are unable to eliminate, may accumulate in them ； (Such as certain dusts.) In summary: we are well aware that these harmful substances are detrimental to us ； We don’t want it to be present in our environment; if PPE is available, it’s best to wear it, even if the level is below the **specified limit ；
It should be worn; a level below the **standard does not mean that there are no harmful substances present. Many harmful substances can still cause chronic poisoning as a result of long-term exposure at low doses.
