Inhalation of asbestos in large quantities is hazardous to the body. Generally asbestos hardly causes harm, it is inhaled by people that will endanger their health. The main harm lies in the fact that asbestos dust, when inhaled by the human body, will attach and deposit in the lungs for a long period of time, and thus may lead to pulmonary fibrosis, pleural damage, etc. Asbestos fibers, if inhaled in large quantities, may cause respiratory symptoms, such as coughing and tightness of the chest, etc. You should take proper precautions when exposed to asbestos by wearing good masks, gloves Or use other items for protection. If there is coughing and sputum, shortness of breath, chest tightness and other unknown symptoms, it is recommended to go to the hospital as soon as possible, under the guidance of a professional doctor to check the lung CT, or chest radiographs to clarify the specific progress of the disease, and usually should be regularly to the hospital for re-examination, to find out the lesions as early as possible.
