Occupational Health and Poisoning Risk Assessment at a Crude Oil Port

Abstract

The throughput of crude oil port is huge, and there are many toxic substances in crude oil, and the cumulative contact effect of toxic substances is obvious because the single operation time of the crude oil port operators is long. The purpose of this study is to investigate the hazard status of crude oil port and evaluate the occupational health and poisoning risk level, so as to provide crude oil operator for risk control. In order to evaluate the occupational health and poisoning risk of crude oil port operators, and to better protect operators, the exposure ratio was determined based on the detection of benzene and hydrogen sulfide concentrations, the main hazard factors of crude oil. Comprehensive analysis of benzene and hydrogen sulfide hazard characteristics, contact ratio, hazard control measures, exposure time and other factors of the exposure index, using the comprehensive index method to determine the exposure level, and finally determine the occupational health and poisoning risk of operators. To determine the occupational health and poisoning risks of workers. The assessment indicated that the risk rating for exposure to benzene and hydrogen sulfide was moderate, but there were weaknesses in hazard control measures. Once the protective effect of sanitary engineering is weakened or invalid, the workers will suffer serious occupational health and poisoning harm. To reduce occupational health and poisoning risk, operators should strengthen on-site monitoring of benzene and hydrogen sulfide concentration and personal protection.
