GB 16852.2-1997

This standard provides diagnostic criteria and guidelines for identifying occupational acute chemical poisoning that occurs through hidden or unrecognized exposure routes, such as inhalation of fumes or skin contact with hazardous substances in the workplace. It is applied by occupational health physicians and industrial hygienists in China to evaluate workers in manufacturing, chemical processing, and other high-risk industries where acute chemical exposure may not be immediately obvious. The standard aids in standardizing diagnosis, ensuring timely treatment, and preventing further health deterioration in affected employees.
