Abstract:

Objective To investigate the current status of occupational hazards in some waste incineration power generation enterprises in Gansu Province,analyze the comprehensive risk level,and provide a basis for occupational disease prevention and control in related enterprises. Methods Data on occupational hazard factor detection and evaluation from 2022 to 2024,occupational health examinations and the configuration of occupational disease protection facilities from 2021 to 2025 were collected from five domestic waste incineration power generation enterprises in Gansu Province. Occupational hazard job classifications were conducted according to current national standards,followed by a comprehensive risk classification assessment. Results The primary occupational hazards identified in these enterprises included silica dust,hydrogen sulfide,ammonia,carbon monoxide,sulfur dioxide,hydrogen chloride,nitrogen oxides,high temperature,and noise. The qualified rates for the concentration or intensity of each hazard factor were 100%. Among the main positions,the operational grading results for hazard factors showed that 1 positions(2.7%) were classified as Level I or above,while 36 positions(97.3%) were classified as Level 0 or do not meet the grading criteria,and the comprehensive risk category for all enterprises was Class B. Conclusion The overall occupational hazards in domestic waste incineration power generation enterprises in Gansu Province are currently under control. However,due to the relative complexity of the hazards,certain positions still pose relatively high risks. It is recommended to implement integrated management measures focused on key control points,strengthen regulatory oversight and technical support,and continuously improve the level of occupational disease prevention and control.
