Monocrystalline silicon itself is not toxic, generally does not harm the human body, but in the processing process because it will use some strong electromagnetic radiation machine, may have a radiation effect on the human body, while monocrystalline silicon in the processing of the powder will be produced, if inhaled too much, may cause pneumoconiosis, silicosis and other diseases. If just simply normal use of processing completed monocrystalline silicon, usually does not produce significant harm to the human body, but if the patient long-term monocrystalline silicon production environment in the office, may lead to inhalation of too much dust containing silica or other harmful substances, and cause lung lesions, silicosis and other diseases, can be coughing, chest tightness, chest pain, and other symptoms, the serious will be respiratory failure, persistent high fever. Therefore, if patients need to carry out related work or need to be in the relevant environment, they need to take strict personal protection measures, such as wearing dust masks, protective clothing and gloves. If the patient suffers from silicosis and other diseases, there is no effective treatment, only through the oxygen inhalation treatment to help patients to relieve the symptoms of respiratory distress, but also through the use of sensitized wheat injection, kesipine and other drugs to alleviate the development of the disease and control the inflammatory reaction. In addition, if the patient needs to process monocrystalline silicon, need to strictly control the dust content, if there is discomfort, should go to the hospital in a timely manner to check, and recommend that patients develop the habit of regular physical examination, can effectively protect the body’s health.
