1. Teach: through publicity and education, unify the understanding, everyone participates in dust prevention work, so that the dust hazard is reduced to a minimum.
2. Revolution: that is, technical innovation. Through the improvement of process flow and operating methods, production automation, mechanization, closed, eliminating the source of dust or reduce dust flying.
3. Water: water dust, wet operation. Mainly in the crushing, grinding and other processes, try to use wet raw materials, water grinding, water research, to eliminate the dust fundamentally; or in the workshop in the appropriate amount of spray water, reduce dust flying.
4. Dense: airtight operation. When the production process allows the use of wet operation or has been used in wet operation still does not meet the dust requirements, the dust source can take closed measures, without prejudice to the operation of the premise, as far as possible to the source of dust, equipment enclosure, in order to prevent dust from escaping into the workshop, or the use of automated equipment, so that the operator is separated from the work site.
5. Wind: ventilation and dust removal. Generally refers to the use of local ventilation in conjunction with the confinement measures, the use of air extraction methods, in the confined enclosure to create a certain negative pressure, control dust does not escape. This type of dust collector has cyclone dust collector, bag type dust collector, electrostatic dust collector, foam type dust collector and impact type dust collector.
6. Protection: personal protection. In taking "water, dense, wind" and other measures, supplemented by personal protective equipment, such as masks, dust masks, protective helmets and dust-proof clothing and other measures.
7 tube: strengthen supervision and management. Due to improper operation or dust removal equipment in the production of improper use, maintenance and management, may artificially cause dust flying. Therefore, strengthen supervision, management, dust control has positive significance.
8. Check: regular inspection, including regular determination of the workplace dust concentration in the workshop, timely understanding of the health of workers in dust operations, supervision and inspection of the implementation of the dust control system, the use of dust control equipment, maintenance.
Legal basis
Environmental Protection Law, Article 42 of the pollutant-emitting enterprises, institutions and other producers and operators, shall take measures to prevent and control the production and construction or other activities in the production and construction of exhaust gases, wastewater, waste, medical waste, dust, malodorous gases, radioactive substances, as well as noise, vibration, optical radiation, electromagnetic radiation and other pollution of the environment. electromagnetic radiation and other pollution and hazards to the environment. Enterprises and institutions discharging pollutants shall establish a responsibility system for environmental protection, and clearly define the responsibilities of unit heads and relevant personnel. Key emission units shall install and use monitoring equipment in accordance with relevant state regulations and monitoring standards, to ensure the normal operation of monitoring equipment, save the original monitoring records. It is strictly prohibited to discharge pollutants illegally through concealed pipes, seepage wells, seepage pits, irrigation or tampering, falsification of monitoring data, or improper operation of pollution prevention and control facilities to avoid supervision
