Prevention of electrostatic hazards in warehouses
1. The materials should be controlled to avoid static electricity as much as possible. For example, for flammable liquids, the flow rate in the pipeline should be restricted, and the loading and unloading methods should be controlled to prevent the mixing of different oils and solvents and prevent water and gas from being trapped in the liquid. 2. Take measures to dissipate the generated static electricity as soon as possible to avoid accumulation. For example, installing a good grounding device on the equipment, increasing the relative humidity of the workplace, laying a conductive floor on the ground, spraying conductive paint on some tools, etc. are all conducive to the discharge of static electricity. 3. Add a certain amount of countercharge to the charged body to neutralize the charge on the charged body and avoid the increase of static voltage. Such as the use of inductive electrostatic neutralizers belong to this type of method. 4. In some cases, the accumulation of static electricity is unavoidable, and the rapid rise of static voltage may even generate static discharge sparks. Measures must be taken to prevent fire and explosion accidents even though the discharge will occur. For example, fill the space of a flammable liquid storage tank with inert gas such as nitrogen, install a control alarm device, and use a high-efficiency exhaust device to prevent the flammable gas or dust in the air from reaching the explosion limit. 5. In places with fire and explosion hazards, such as chemical dangerous goods storage places, the staff wear conductive shoes and static conductive overalls, etc., to eliminate the static electricity on the human body in time, which is also one of the effective measures to prevent static electricity hazards.
