Prevention of electrostatic hazards of packaging in warehouses
In the storage of packaged goods, the following steps are generally used to prevent and control the harm caused by static electricity.
1. The packaging should be controlled as far as possible not to generate static electricity. For example, for flammable liquids, it is necessary to limit violent shaking in the packaging barrel, control its loading and unloading methods, prevent different oil leakage and mixing, and prevent water ingress in the steel barrel. .
2. Take measures to dissipate the generated static electricity as soon as possible to avoid accumulation. For example, installing good grounding devices on handling tools, increasing the relative humidity of the workplace, laying conductive floors on the ground, spraying conductive paint on certain tools, etc. are 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 inevitable, and the rapid rise of static voltage may even produce static discharge sparks. Measures must be taken to prevent fire and explosion accidents despite the discharge. For example, fill the flammable liquid storage space with inert gas, install a controlled alarm device, and use a high-efficiency exhaust device to keep the flammable gas or dust in the air below the explosion limit.
5. In places with fire and explosion hazards, such as storage places for chemical dangerous goods, the staff wear conductive shoes and static electricity overalls, etc., to eliminate the static electricity of the human body in time, which is also one of the effective measures to prevent static electricity hazards.
