â‘  prevent air pollution: pollution of major welding fume handling mainly the use of local ventilation, ventilation, supplemented by a comprehensive means to strengthen personal protection, thus improving the operating environment pollution. â‘¡ prevent light pollution: the scene illumination concentrated exposure, covering only live ranges. Set around the work area, isolating shed, the welding arc is generated Flux Cored Welding Wire in optical isolators in the construction area. â‘¢ prevent the construction of noise pollution: the construction site to promote civilized construction, establish and improve the governance of man-made noise control system. Construction site noise machinery (such as air compressors, welding machines, arc planing, grinding machines, etc.) to set the closed shed isolation to reduce noise from spreading. â‘£ solid waste management: construction trash containers used lifting, non-random throw. The establishment of specialized construction site waste temporary storage sites. Regular production process waste collection towel collection, to approve the construction unit of the unit or premises for processing, consumer satisfaction.
