The Ministry of Labor officially promulgated the Regulations Governing Assessment and Control Banding of Hazardous Chemicals in 2015, requiring employers to classify chemicals according to CNS 15030 and take necessary measures to contain hazardous chemicals based on their classifications. The Regulations provide grading principles for permissible exposure limits (PELs) and working environments that should be monitored and incorporate chemical control banding (CCB) tools with all new concepts for qualitative and semi-quantitative exposure assessment. The simple and effective implementation procedures can enhance the prevention of chemical hazards.
In compliance with the Regulations, this study selected an existing chemical management system (CMS) of a research institute and expanded its indexing and control banding functions. This study investigated current regulations and system conditions to understand the discrepancies between the system and regulatory requirements and then employed Deming’ PDCA to improve the system and apply it to operations in its laboratory to verify its appropriateness.
The laboratories selected for this study handle hazardous chemicals, which were assessed and classified to identify operating sites with high risks, residual risks, or regulatory non-compliances. At the same time, this study develops CMS-CCB procedures. The results indicate that the exposure prevention measures at the operating sites all complied with CCB suggestions. Detected and estimated exposure concentrations are compared with PELs for operating sites, and the results reveale that 2% of the assessment items belong to Category 3 and requires immediate improvement, while 48% necessitate further monitoring or assessment. The results of this study provide reference to the case study laboratories for further assessment and improvement. This study also examined the benefits of implementing CCB in the laboratories of the institue. It is hoped that the CCB can effectively reduce potential occupational safety and health risks.
