Occupational disease hazards include

With the development of society, many people will develop a series of occupational diseases due to the influence of long-term work and the working environment. Some people think that occupational diseases are actually nothing and they will only affect our daily lives. But are the hazards of occupational diseases in real life the same as we think? If you think so too, then you can read the article below to give you a full and clear understanding of occupational diseases, and perhaps you will find the shortcomings of your understanding.

(I) Harmful factors generated during the production process

1. Chemical factors

(1) Toxic substances, such as lead and mercury. In the process of ethylene production, there are poisons such as benzene, toluene, ethylbenzene, and styrene. In the process of producing styrene-butadiene rubber, there are dozens of poisons such as butadiene, styrene, high aromatic oil, sodium nitrite, and diisopropylbenzene peroxide.

(2) Production dust, such as petroleum coke dust in the oil refining process, aluminum silicate powder (dust-like) used as catalyst, etc.; metal dust, cement dust, etc. in the catalyst production process, in addition, there are asbestos dust, coal dust, etc.

2. Physical factors

(1) Abnormal meteorological conditions, such as high temperature, high humidity, low temperature, etc.

(2) Abnormal air pressure, such as high pressure or low pressure.

(3) Noise and vibration.

(4) Non-ionizing radiation, such as visible light, ultraviolet light, infrared light, radio frequency, microwave, and laser.

(5) Ionizing radiation, such as X-rays and gamma rays produced by radioisotope instruments.

3. Biological factors, such as anthrax attached to fur and mold on bagasse. Rare in the petrochemical industry.

2. Harmful factors in the labor process

The labor process refers to the labor organization, operating positions and methods, and the proportion of physical and mental labor in the production process. The harmful factors generated in this process include:

① During major overhauls or emergency repairs, unreasonable labor organization and systems, unreasonable labor work and rest systems, etc. are prone to occur; ② Mental stress: The high degree of automation and the replacement of heavy physical labor and manual operations by instruments also bring about mental stress problems. ③ Excessive labor intensity or inappropriate production quotas, such as the arranged work is not compatible with the physiological condition of the employees; ④ Excessive tension in individual systems or organs, such as visual tension; ⑤ Being in a certain bad posture for a long time or using unreasonable tools.

(III) Harmful factors in the production environment

The production environment can be a natural environment or an artificial environment established according to the needs of the production process. Occupational hazards in the production process include:

① Factors in the natural environment, such as solar radiation in hot seasons; ② Improper building construction or layout, such as arranging toxic and non-toxic work sections in the same workshop; ③ Environmental pollution caused by unreasonable production processes, such as chlorine leakage from chlorine recovery, refining, and liquefaction stations, which sometimes causes pollution to the surrounding environment of 10 to 20 meters.

In actual production, occupational disease hazard factors often do not exist alone. The combined existence of multiple occupational disease hazard factors can often aggravate the impact on workers' health.
