◉ Introduction to Hazardous Substances in the Workplace
The exposure limit value of occupational harmful factors refers to the allowable exposure level at which workers are repeatedly exposed for a long time in the course of occupational activities without causing harmful effects to the health of the vast majority of contacts. Occupational exposure limits for chemically hazardous factors include time-weighted average allowable concentrations, short-term exposure allowable concentrations and maximum allowable concentrations.
Chemical harmful factors include not only chemical substances and dust, but also biological factors.
