Vietnam consults draft regulation on safety management of hazardous chemicals

On July 21, 2020, the Ministry of Industry and Trade (MOIT) of Vietnam released a draft “National Technical Regulation (QCVN) on safety management in the manufacture, storage, transport and use of hazardous chemicals”, and invited comments on it. The draft will apply to organizations and individuals engaged in activities related to hazardous chemicals in Vietnam, regulating hazardous, toxic, flammable and explosive, and corrosive substances.

 

Technical provisions

The proposed national technical standard specifically sets forth the following requirements for manufacture, storage, and transport of hazardous chemicals
