How should static electricity be controlled at work?

In chemical production, the media used in most processing units are flammable and explosive, and very little ignition energy is required to set them on fire. When leaks or accidents occur during production, flammable and explosive gases, liquid vapors, suspended dusts, or fibers combine with air to form combustible mixtures; in such situations, even weak static electric sparks generated by materials, equipment, structures, or human bodies can lead to fires or explosions, posing a serious threat to safe production. If static sparks are carried by a person as they walk and reach the production area, they can become a dangerous ignition source that is highly mobile, difficult to detect, and hard to control. Therefore, static electricity poses a significant threat to safe production, product yield and quality, the stable operation of equipment, and environmental protection, and cannot be ignored. Therefore, how should static electricity be prevented during production to take precautions in advance?
Static bonding of flanges, grounding of equipment, lightning protection inspections twice a year~!
By what means is this detection carried out?
This needs to be sent to the local meteorological bureau for on-site testing, and a test certificate will be issued upon completion~!
Thank you; this also needs to be tested by a testing department with specific qualifications~
1. Reduce the generation of static electricity. Such as reducing the flow rate, etc. 2. Export static electricity in a timely manner
1. Install human body static electricity discharge columns at the entrances and exits of the production unit area, tank farm, and loading/unloading area； 2. Flange bonding in the production area, and grounding of various equipment, frames, storage tanks, power distribution rooms, control rooms, analysis systems, and utility equipment ； 3. Entrust the meteorological department to conduct on-site inspections ； 4. The enterprise regularly inspects all facilities on its own ； 5. Reduce flow velocity during loading and unloading.
Measure the ground resistance; it should not be greater than 100 ohms
The main ones are grounding, discharge grounding posts, work clothes, tools, and so on
Static electricity generated by the medium in pipes and equipment: Use flange static discharge wires and static grounding wires; reduce flow velocity. Static electricity generated by humans: Wear appropriate clothing, use cotton inner and outer garments; install human static electricity dissipators.
Besides wearing synthetic fiber clothes that tend to generate static electricity, what other measures should be taken to prevent static electricity from forming in the human body?
