In many production processes within the plastics industry, the danger of static electricity is immense, as it can affect product quality and potentially lead to fires and explosions. In the workplace, all fire and explosion incidents caused by static electricity follow the same procedure: first, charge separation occurs, followed by charge accumulation. If the charge cannot escape, a static discharge happens. When combustible materials are ignited, there is a risk of fire and explosion.

Static electricity hazard control methods can be categorized into five types: grounding, humidification, speed limitation, antistatic materials, and static eliminators. During the industrial production process, due to variations in the working environment, procedures, and materials, the prevention and control methods for static electricity hazards will also differ. During the selection process, factors such as the process environment, conditions, and limitations, as well as funding, management systems, and personnel quality must be considered. No single static electricity hazard control method is suitable for all industrial processes or situations. Sometimes, two or more static electricity hazard control methods are used simultaneously.

Most industrial processes generate static charge buildup, causing discomfort, harm to the human body, and even fire and explosion accidents. The occurrence of these static hazards must follow certain development stages. Firstly, static electricity is produced by friction, induction, or conduction, then accumulates different polar charges on equipment, personnel, or products. These charges continue to accumulate until they are sufficient to cause a discharge phenomenon. The energy released by the static electricity is enough to ignite surrounding flammable materials, leading to fires or explosions. Understanding the various stages of static hazard formation helps identify the causes of static hazards, formulate corresponding control measures, thereby enhancing the safety of the production site and operators, and effectively reducing static hazards and production losses.
