Electric welding smoke occupational disease hazard risk assessment method

Abstract

The invention provides an electric welding smoke occupational disease hazard risk assessment method, which comprises the following four aspects: a risk understanding module for understanding related information of electric welding smoke and understanding the harm of the electric welding smoke to human health; the risk research module that is used for researching historical data of electrowelding smoke exposure concentration and related data of epidemic diseases easily infected by people; the risk calculation module that is used for carrying out field detection on the concentration of the electric welding smoke dust according to historical data of the exposure concentration of the electric welding smoke dust, obtaining a concentration change diagram, carrying out analog calculation on the relationship between the change of the electric welding smoke dust in the lung of a person and the risk, and finally calculating the distribution condition of the risk; and the risk evaluation module that is used for evaluating and analyzing a result of the risk calculation module. According to the invention, SPSS software is utilized to make a concentration distribution diagram of the electric welding smoke dust, a dose-reaction model is utilized to simulate the relationship between the change of the electric welding smoke dust in the human lung and the risk, and finally Crystal ball software is utilized to perform Monte Carlo simulation to calculate the distribution condition of the risk.

Description

technical field [0001] The invention belongs to the field of smoke and dust occupational disease hazard risk assessment methods, in particular to an electric welding smoke and dust occupational disease hazard risk assessment method. Background technique [0002] Welding fume is a kind of soot produced under high-temperature combustion when the welding rod contacts the weldment during the electric welding process. This kind of soot contains manganese dioxide, nitrogen oxides, fluoride, ozone, etc. cause harm. The particle size of welding fume is very small, and most of them are respirable dust. When the operator performs welding operations in a poorly ventilated and protected environment for a long time, he may be exposed to occupational hazards. Therefore, ventilation measures are taken to reduce the risk of workers The concentration of smoke and harmful gases in the air in the breathing zone is extremely important to protect the health of operators. [0003] With the deve...
