The European Union strengthens the implementation of the SDSs quality improvement project. Starting from January this year (2017), auditors from EU member states will focus on the safe use guidelines for hazardous substances in chemical substance safety data sheets (SDSs), in accordance with REACH Regulation 5 This law enforcement project requires that the quality of information disclosure be strengthened. The General Administration of Chemistry stated that the main purpose of this project is to ensure that production line employees can understand the dangers of chemical substances and use them in the correct way when they are exposed to harmful chemicals. When auditors perform inspections, they will focus on whether the information in SDSs is consistent with the information in Chemical Safety Reports (CSRs) created by chemical manufacturers. The auditor will also review the exposure scenarios (Exposure Scenario) that should be attached to the SDSs. Finally, through auditors' reports and statistical analysis of data, the General Administration of Chemical Industry will evaluate the current communication efficiency of this important information from the source chemical substance manufacturer, through the product manufacturing supply chain, and finally to the hands of consumers. intensity, and will use the results of this implementation project to formulate the chemical substance information management method for the next stage. The project will also work with labor inspectors in each member country to collect information on whether manufacturers have implemented chemical substance management systems and whether production line employees correctly understand the safe use of chemical substances.
