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.
