What is productive dust? In general, solid particles that are produced during the production process and can float in the production environment for a longer period of time. The harmful effects of productive dust on the human body are numerous, but the most prominent hazards are manifested in the lungs. Due to differences in the nature of dust and chemical components, the hazards to the lungs vary greatly. According to the performance after the victimization, the lungs caused by dust are affected. Part of the disease can be divided into three situations.

The first is pneumoconiosis. This is one of the major occupational diseases. Our country has already been classified as a statutory occupational disease. This disease is caused by inhalation of higher concentrations of productive dust for a prolonged period of time, which causes systemic diseases characterized by pulmonary fibrosis. As there are many types of pneumoconiosis, there are many types of pneumoconiosis, including silicosis, asbestosis, talcosis, mica lungs, coal lungs, coal lungs, and carbon pneumoconiosis.

The second is pulmonary dust deposition, which is caused by the inhalation of certain metallic dust or other dust that causes the dust to settle in the lung tissue, thus presenting a foreign body reaction, which is less harmful than pneumoconiosis.

The third is dust-induced lung disease reactions and allergic diseases. These diseases are mainly caused by organic dust, such as cotton dust, hemp dust, fur dust, and wood dust.

The production of dust is harmful to the human body and is affected by many factors. The first is the chemical composition and nature of the dust. The dust with high free silica content is more harmful than the lower one. Dust containing free silica is more hazardous than free silica. Followed by the particle size of the dust, in general, large particles of dust easily fall, drift in the air for a short time, not easily inhaled, will not cause harm.

In addition, the dust in the lung tissue, the size of the dust, the proportion of dust, morphology, hardness and other hazards to the human body have a certain relationship. Do workers who engage in dust operations do harm? The key lies in the good or bad protection, and often pay attention to protection, can minimize the harm, and even completely control and eliminate dust hazards. Dust prevention should take comprehensive measures, mainly from the following aspects to solve.

Prevention of pneumoconiosis is very beneficial to protecting the health of workers and economic development. China has many creative experiences in dust prevention, such as wet work, closed dust sources, ventilation and dust removal, personal protection, maintenance and inspection of equipment, determination of dust concentration in the air, We vigorously carried out a comprehensive set of dust prevention measures such as publicity and education. The concentration in the production environment is often related to the cleaning system. Therefore, attention should be paid to the cleanliness of the environment. The implementation of sweeping can effectively reduce dust concentration.

1. Strengthen the organization and leadership, formulate dust-proof rules and regulations, provide special and part-time personnel, and give guarantees from the organization. Strict health checks should be conducted for the employed personnel. All active and internal lung tuberculosis and various respiratory diseases (rhinitis, asthma, bronchiectasis, chronic bronchitis, emphysema, etc.) should not be used for dust exposure. Workers engaged in dust exposure regularly undergo physical examinations every year. If pneumoconiosis is found, they are immediately mobilized for active treatment.

2, gradually reform the production process and production equipment, wet operation mode, reduce the dust flying.

3, reduce the concentration of dust in the air, seal the machinery to prevent dust from escaping, use ventilation and exhaust devices and air purification dust removal equipment, so that the workshop dust to the national occupational exposure limits below the standard. 4, to strengthen personal hygiene protection, dust operators should wear overalls, work caps, reduce the body exposed parts, according to the nature of dust, choose to wear a variety of dust masks to prevent dust from inhaling the respiratory tract, causing harm.
