Detection of occupational hazards is a scientific method aimed at preventing occupational diseases. By detecting the hazardous factors in the workplace, the risk degree of occupational diseases in the workplace can be evaluated. Because the hazard factors of occupational diseases are very complex and diverse, the detection methods of different jobs and environments are also different, so the detection of occupational disease hazard factors is generally divided into the following aspects. The first is the detection of physical factors, including noise, vibration, illumination, ionizing radiation, high temperature, low temperature, air pressure and static electricity. Noise detection is a key step to judge whether there is noise exceeding the standard, and it is generally necessary to detect sound intensity, frequency and duration. Vibration detection needs to analyze the magnitude, frequency, duration and other factors of vibration to understand whether it meets the standard. Illumination detection needs to analyze factors such as illumination intensity and illumination time to determine whether there is too strong or too weak illumination. Ionizing radiation detection is to detect the intensity and frequency of radiation in this place with professional instruments to judge whether there is any danger of exceeding the standard. High temperature, low temperature and air pressure generally need to detect the room temperature, humidity, air pressure and other parameters of the place to judge whether it meets the standard. Electrostatic detection needs to detect whether there is static electricity in the place, and the interference of static electricity to electronic equipment needs to be detected.
Secondly, the detection of chemical factors, including toxic gases, toxic liquids, dust, metals, chemicals and so on. Toxic gas detection is to detect the concentration, type and source of toxic gas in the air with professional instruments to judge whether it meets the standard. The detection of toxic liquid needs to detect the toxic components and concentration in the liquid to know whether it exceeds the standard. Dust detection needs to detect dust concentration, particle size, composition and other parameters in the workplace to know whether there is dust exceeding the standard. Metal detection needs to detect the types, concentrations, forms and other factors of metals, so as to know whether there are any metals exceeding the standard. Chemical detection needs to detect the types, concentrations, forms and other factors of chemical substances, so as to know whether there are any chemical substances exceeding the standard.
Finally, the detection of biological factors, including bacteria, viruses, fungi, parasites and so on. These biological factors need professional instruments to detect whether there are these organisms in the site, and to determine their quantity and activity, so as to understand whether there are organisms exceeding the standard.
In short, the detection of occupational hazards requires a comprehensive and in-depth understanding of the situation in the workplace, and analysis through various instruments and methods to find out whether there are occupational hazards, so as to take corresponding protective measures to ensure the health and safety of employees.
