There is a specific process for the generation of electrostatic hazards, which is helpful for a systematic understanding of the dangers caused by electrostatic discharge ignition. In the working environment, all fire and explosion events caused by static electricity follow the same procedure, as described below: First, charge separation occurs, and then charge accumulation occurs. If the charge cannot be dissipated, electrostatic discharge will occur, and the surrounding easy Flammable substances and fire and explosion hazards.
Methods for preventing static hazards can be divided into five types: grounding, increasing humidity, limiting speed, antistatic materials, and static eliminators. In the industrial manufacturing process, due to different operating environments, procedures and materials, the methods of preventing electrostatic hazards implemented will also be different. Factors such as on-site process environment, conditions and restrictions, and even funding, management systems, and human resources must be considered when selecting. There is no one static electricity prevention method that can be applied to all industrial processes or situations, and sometimes two or more static electricity prevention methods are used at the same time.
Most industrial processes may generate static charge accumulation, ranging from discomfort to lightness and harm to the human body, and even cause fire and explosion accidents. The occurrence of these electrostatic hazard accidents must have the following development process. First, static electricity is generated due to friction, induction or conduction, and then charges of different polarities are accumulated on equipment, personnel or products, and the charges continue to accumulate enough to cause Discharge phenomenon, and when the energy released by electrostatic discharge is enough to ignite surrounding flammable substances, it will cause fire or explosion disaster. Each phase of the formation of electrostatic hazards is clear, which helps to identify the causes of electrostatic hazards, and develop appropriate preventive measures to achieve the improvement of the safety of process sites and operating personnel, and effectively reduce electrostatic hazard accidents and production losses.
