Abstract:

At present，in China's occupational health standard system，the "Occupational exposure limits for hazardous agents in the workplace Part 2：Physical agents"（GBZ 2.2-2007）specifies occupational exposure limits for various physical agents in the workplace. The "Measurement of physical agents in workplace"（GBZ/T 189 series） specifies the measurement methods for various physical agents in the workplace. Most of the existing occupational exposure limits and measurement methods for physical agents in the workplace have been implemented for nearly 20 years. And the limits and measurement methods for some physical agents mainly follow the standards of the 1980s and 1990s. This paper focuses on discussing the problems encountered in actual measurement and evaluation processes of different physical agents and providing suggestions.
