The weather is getting colder in winter, and doors and windows are often closed in indoor workplaces. Due to the lack of ventilation facilities in some workplaces, toxic and harmful substances cannot be discharged in time, leaving hidden dangers for safe production. In winter, doors and windows are closed, ventilation facilities in some workplaces are not good, and a large number of toxins gather in the air. Over time, people who work in this environment are prone to occupational diseases. Because the clinical manifestations of some occupational diseases are not obvious, some people are not easy to find even if they are sick, such as pneumoconiosis, which is the most serious occupational disease that harms health, with high incidence and more pain to patients. This disease has no specific clinical manifestations and is mostly related to complications, such as cough, expectoration, chest pain and dyspnea.

Experts remind professional workers to know whether there are occupational hazards in their work before taking up their posts. If there are, they should take corresponding occupational protection measures and sign labor contracts according to law. When working in the workplace with occupational hazards, do not close the doors and windows, pay attention to the use of ventilation facilities and open windows for ventilation, so that harmful substances can be discharged in time and not accumulated indoors; Don't stay in the workplace to keep warm. Eating and living are separated from the workplace. In addition, people who are exposed to cotton dust should not smoke in the working environment. If textile workers smoke, smoke will accelerate the destruction of human resistance and the ability to clear the upper respiratory tract, leading to respiratory tract infection and promoting the formation of bronchitis.
