Does graphene production fall under the category of hazardous chemical production?
Thread Content
Our company is building a new graphene production line. When formulating the safety regulations, we are unsure whether graphene production should be classified as part of hazardous chemical production; it isn’t listed in the catalog of hazardous chemicals either. We would appreciate some guidance from those with expertise in this area.
Graphene is a relatively new technology; it’s possible that the relevant regulations have not yet been updated. However, the production of graphene involves hazardous substances such as sulfuric acid, so safety measures must not be neglected
You can consult the provincial hazardous chemicals registration center or **the relevant departments to find out whether graphene is considered a hazardous chemical. If it isn’t, then no safety production license is required; if it is, then one is necessary.
Although the product itself is not a hazardous chemical, if the raw materials and auxiliary substances are hazardous chemicals, the production and storage process must be managed in accordance with the regulations applicable to hazardous chemical enterprises
Auxiliary materials include acids, bases, as well as hydrogen sulfide and methane produced during the production process.
It can be confirmed only after a property test is conducted
It depends on the production process you use. If CVD (Chemical Vapor Deposition) is employed, methane is usually used as the material, and such processes fall under the category of hazardous chemical production. If graphite oxidation followed by reduction is used, graphite serves as the raw material; however, this method basically cannot produce genuine graphene as it results in defects, and therefore it should not be classified as hazardous chemical production. It is necessary to consult the relevant regulatory authorities to determine whether it falls under this category. Once production begins, the work safety supervision agency will need to oversee the process. If it is considered hazardous chemical production, it will be under the jurisdiction of the hazardous chemicals department, while if it isn’t, it will fall under the jurisdiction of the industry and trade department
Take a look at the approval from the National Development and Reform Commission and the design of the safety facilities
Got it, thanks to everyone for their help
