Occupational disease hazard evaluation method and system based on noise exposure

Abstract

The invention discloses an occupational disease hazard evaluation method and system based on noise exposure, and the system comprises an occupational hazard factor module, an exposure risk prediction module, and a risk evaluation and management module. The exposure risk prediction module is used for carrying out risk prediction calculation on the obtained data, the risk assessment and management module carries out judgment and assessment according to the calculated data and a set threshold value, and the industry hazard factor module is electrically connected with the exposure risk prediction module. The exposure risk prediction module is electrically connected with the risk assessment and management module, required data is provided for occupational disease prevention control and risk analysis, the data is the basis and guarantee of noise exposure occupational disease hazard prevention control and risk analysis, and an assessment database is obtained and established through testing for risk management. The method has the characteristic of guiding enterprise noise to implement risk assessment and risk management.

Description

technical field [0001] The invention relates to the technical field of occupational disease hazard evaluation, in particular to a noise exposure-based occupational disease hazard evaluation method and system. Background technique [0002] The automobile manufacturing process is complex, mainly including four types: welding, painting, final assembly and stamping. The types of occupational disease hazards in the automobile manufacturing industry are directly related to the production raw materials and processes. The raw materials and production processes are different, and there are many factors for occupational diseases. Diverse, including dust, poisons and various physical factors, about forty kinds of poisons are involved. Occupational diseases are harmful and widely distributed. At present, occupational noise exposure has become an increasingly prominent occupational health problem that endangers the physical and mental health of occupational groups. Occupational noise-induc...

Problems solved by technology

[0003] Noise-induced hearing loss is one of the most important occupational diseases in many countries in the world. The World Health Organization estimates that 466 million people worldwide suffer from hearing loss, and 16% of adult hearing loss may be caused by occupational noise exposure. Workers with hearing loss Communication skills and alertness are reduced, leading to reduced productivity and increased risk of injury. In addition, noise hearing loss can have various adverse consequences such as fear and depression as well as non-auditory health effects such as cognitive impairment and cardiovascular disease. Risk assessment It is to judge the degree of impact or loss that may be caused by an event or thing. It is possible to objectively understand the risk factors that exist in things or systems. By identifying and analyzing these factors, it is possible to judge the possibility and severity of harm, and then take appropriate measures. In the process of reducing the probability of risk, the current noise risk assessment method involves too few factors in the calculation of hearing loss risk prediction, and the existing data from automobile manufacturers on noise-induced hearing loss and its assessment are even more incomplete. The accuracy of the risk assessment results of the database is low. Therefore, it is necessary to design an occupational hazard assessment method and system based on noise exposure to guide enterprises to implement noise risk assessment and risk management.
