What is the eight-character policy of dust hazard prevention and control measures
1. teaching: through publicity and education, everyone should participate in dust prevention work to minimize the harm of dust.
2. Leather: that is, technological innovation. By improving the process flow and operation method, production automation, mechanization and sealing can be realized, and dust sources can be eliminated or dust flying can be reduced.
3. Water: water for dust removal and wet operation. Mainly in the process of crushing and grinding, wet raw materials, water mills and water mills are used as much as possible to fundamentally eliminate dust; Or sprinkle water in the workshop to reduce dust flying.
4. Secret: Closed operation. When the production process allows wet operation or wet operation still cannot meet the dust removal requirements, the dust source can be sealed, and the dust source and equipment can be sealed as much as possible to prevent dust from escaping into the workshop, or automatic equipment can be used to let the operators leave the work site.
5. Wind: ventilation and dust removal. Generally speaking, it refers to local ventilation used in conjunction with sealing measures. Through ventilation, a certain negative pressure is caused in the closed cover to control the escape of dust. This kind of dust collector includes cyclone dust collector, bag dust collector, electrostatic dust collector, foam dust collector and impact dust collector.
6. Protection: Personal protection. In addition to taking measures such as "water, density and wind", personal protective equipment such as masks, dust masks, protective helmets and dust suits are also added.
7 management: strengthen supervision and management. Due to improper operation in production or improper use, maintenance and management of dust removal equipment, dust may fly artificially. Therefore, strengthening supervision and management is of positive significance to dust prevention.
8. Inspection: regular inspection, including regular measurement of dust concentration in the workplace of the workshop, timely understanding of the health status of workers exposed to dust, supervision and inspection of the implementation of various dust-proof systems, and the use and maintenance of dust-proof equipment.
legal ground
"Environmental Protection Law" Article 42 Enterprises, institutions and other producers and operators that discharge pollutants shall take measures to prevent and control the pollution and harm to the environment caused by waste gas, waste water, waste residue, medical waste, dust, malodorous gas, radioactive substances, noise, vibration, light radiation and electromagnetic radiation generated in production, construction or other activities. Enterprises and institutions that discharge pollutants shall establish a responsibility system for environmental protection, and clarify the responsibilities of the person in charge of the unit and relevant personnel. Key pollutant discharge units shall install and use monitoring equipment in accordance with relevant state regulations and monitoring norms, ensure the normal operation of monitoring equipment, and keep original monitoring records. It is strictly prohibited to illegally discharge pollutants through concealed pipes, seepage wells, seepage pits, perfusion or tampering with or forging monitoring data, or the pollution prevention and control facilities are not operating normally to avoid supervision.
