Problems solved by technology

The "Chemical Toxic Occupational Exposure Risk Classification Method" is mainly aimed at small and medium-sized enterprises. Some of the selected occupational exposure factors are not applicable to large petrochemical enterprises, and the index division is not applicable to petrochemical enterprises, so it is not applicable to the occupational hazard risk assessment of petrochemical enterprises.

Abstract

The invention discloses a chemical poison occupational hazard risk grade evaluation method for petrochemical enterprises, and relates to the field of occupational health. The method includes the following steps of investigating and recording operating posts and corresponding operation types in a place to be evaluated, investigating and recording the working time, occupational exposure poisons, the working equipment airtight degree, working equipment operation time of workers and an engineering control measure corresponding to each operation type, determining the hazard grade and the exposure grade of each occupational exposure poison, obtaining the risk grade of each occupational exposure poison in each operation type and risk level grades of the corresponding operating posts according to the poison hazard grades, the poison exposure grades and risk grade evaluation rules, and making a risk evaluation report and a risk control and management report. According to the chemical poison occupational hazard risk grade evaluation method for the petrochemical enterprises, occupational disease prevention resources are used reasonably, the occupational health management efficiency is obviously improved, and the occupational health prevention and control cost of the petrochemical enterprises can be effectively reduced.

Description

technical field [0001] The invention relates to the field of occupational health, in particular to a method for evaluating the risk level of occupational hazards of chemical poisons used in petrochemical enterprises. Background technique [0002] In my country's petrochemical enterprises, there are a large number of occupational hazards such as chemical poisons, dust, and noise in the workplace. Risks are graded, and resources for the prevention and control of occupational disease hazards are allocated according to different hazard levels. [0003] When the existing hazard classification method is used in petrochemical enterprises, there are the following defects: [0004] The risk classification method for occupational exposure to chemical poisons established by the "Risk Analysis-Based Workplace Occupational Hazard Evaluation Technology" divides the exposure index and occupational hazard level (level 5) based on exposure factors such as vapor pressure and dust particles (k...
