Understanding and mastering the concentration or intensity of occupational hazards in the workplace in time, finding occupational hazards as soon as possible and taking protective measures in time to eliminate or reduce the impact of occupational hazards on workers' health are the key links of secondary prevention of occupational diseases. Only through daily monitoring can the employer know and master the concentration or intensity of occupational hazards in the workplace in time. Daily monitoring of occupational hazards is one of the management obligations of the employer's own occupational disease prevention. The employing unit shall determine the daily monitoring points, monitoring items, monitoring methods and monitoring frequency (times) according to the norms formulated by the health administrative department of the State Council and the types of occupational hazards in the workplace, establish a monitoring system, establish a monitoring instrument and equipment use management system and a monitoring result statistical publication reporting system, and set up a special person to be responsible for the implementation and management of monitoring, dynamically observe major occupational hazards, and timely discover and deal with occupational hazards. The employer shall conscientiously implement the relevant monitoring management system to ensure the normal operation of the monitoring system.
(2) Regularly monitor the occupational hazards in the workplace. According to the regulations of the administrative department of health in the State Council, the employer shall regularly detect and evaluate the occupational hazard factors in the workplace. The test and evaluation results are stored in the employer's occupational health files, reported to the local health administrative department regularly and announced to the workers.
The purpose of periodic detection and evaluation of occupational hazards in the workplace is to comprehensively detect occupational hazards in the workplace. On the basis of comprehensive analysis of the detection results, the types, harm degree (concentration or intensity), protective measures and their effects of occupational hazards in the workplace are evaluated, and the hazard categories are determined, which provides a basis for classified management of the workplace, occupational hazard management, occupational disease diagnosis and identification, and law enforcement by health administrative departments.
Occupational health technical service institutions that have obtained qualification certification must be responsible for regular testing and evaluation, and their testing and evaluation conclusions should be objective and fair. The test and evaluation results must be stored in the occupational health archives of the employer, and reported to the local health administrative department and announced to the workers.
(3) If the occupational hazard factors do not meet the national occupational health standards, the operation must be stopped. The fundamental purpose of occupational hazard monitoring, detection and evaluation is to eliminate or reduce the impact of occupational hazards in the workplace on the health of workers and protect their health. Therefore, when it is found that the occupational hazard factors in the workplace do not meet the national occupational health standards and health requirements, the employer shall immediately take corresponding control measures, and if they still do not meet the national occupational health standards and health requirements, the operation with occupational hazard factors must be stopped; After treatment, the occupational hazard factors can meet the national occupational health standards and health requirements before re-operation.
