Note

1

The production equipment, equipment, facilities, storage tanks, and buildings ( structures) shall be designed with reliable lightning protection devices to prevent the harm and damage of lightning to people, equipment and buildings (structures). Lightning protection design should comply with national standards and relevant regulations

 

 

 

2

Overhead pipelines of production equipment, terminal devices for power transmission and distribution equipment, and low-voltage power supply lines shall be designed with protective measures against lightning wave intrusion.

 

 

 

3

Inflammable and explosive buildings and facilities are to be inspected once every six months by lightning protection inspections, and once every year in other buildings; the resistance value should not be greater than 10 Ω.

 

 

 

4

When the grounding conductor passes through the wall, it shall be protected with casing. When crossing the expansion joint, compensation shall be made

 

 

 

5

Put a protective tube over the ground 2 meters above the ground and fix it firmly with a clip. Brush the red and white paint.

 

 

 

6

The grounding line should be painted with black paint. The paint should be evenly leaked, but the clamps and grounding terminals must not be painted.

 

 

 

7

Each building has at least two deflectors (except for buildings with a projected area of ​​less than 50 square meters)

 

 

 

8

All metal parts of the piping system, including the metal cladding of the jacket must be grounded

 

 

 

9

For the non-conductor pipeline section in the middle of the metal pipeline, the metal pipes at the two ends of the non-conductor pipeline shall be connected with the grounding mains and the metal parts at the non-conductor pipeline section shall be grounded, respectively.

 

 

 

10

Pipeline transmission of oil products should try to avoid mixing air, water, dust and other substances

 

 

 

11

All metal parts of the mixing and mixing equipment shall be connected together and grounded; if the equipment has an insulating lining internal grounding measures may be used to promote charge leakage

 

 

 

12

It is forbidden to use compressed air for the blending of gasoline, kerosene, and light diesel oil . Heavy diesel oil, etc. must be controlled when compressed air is used to adjust the wind pressure is not greater than 343kPa , and the oil blending temperature is at least lower than the oil product flash point of 20 °C . If jet mixing is used, the liquid column does not eject the liquid surface and the metal parts of the equipment. Grounding is not a risk of electrostatic ignition

 

 

 

Anti-static facilities

No.

Note

1

All metal equipment, pipelines, storage tanks, etc. in the explosion-proof zone of the production facility must be designed with electrostatic grounding. The internal structure of the equipment and equipment must not be allowed to control the generation of static electricity so that it cannot reach dangerous levels. Non-conductor equipment, pipelines, storage tanks, etc. shall be designed for indirect grounding, or electrostatic shielding methods shall be used, and the shielded body must be reliably grounded.

 

 

 

2

Sites with fire and explosion hazards, production processes with static electricity that affect product quality, and workplaces with static electricity hazards should be grounded. All metal appliances, door and window components, mobile metal vehicles, and ladders should be grounded.

 

 

 

3

Workplaces that may be electrostatically hazardous should be equipped with personal anti-static protective equipment. Fire prevention and explosion-proof operation area entrance should be designed to guide people to remove static electricity

 

 

 

4

The electrostatic grounding point and jumper point of each device and pipe must be firm and easy to use

 

 

 

5

The total leakage resistance of each production device system or device unit should be less than lx105 Ω, and the grounding resistance of each specially- designed electrostatic grounding body should not exceed 100 Ω. Metallic flanges are used between metal equipment and equipment and between pipes and pipelines. It is not necessary to connect the jumper separately when connecting, but there must be more than two bolts, and the total leakage resistance must meet the requirements.

 

 

 

6

Large metal devices with large diameter or large volume should have more than two grounding points. Longer transmission pipelines should have a grounding point every 80-100m.

 

 

 

7

The flow rate in the pipeline must be controlled strictly in accordance with the operating procedures

 

 

 

8

When using metal nozzles or metal funnels to hold oil in metal drums, they must be kept in good contact or connection and grounded reliably. It is forbidden to use insulating containers to fill gasoline, kerosene, etc.

 

 

 

9

When filling the antistatic plastic container with oil, any metal parts on the container must be connected to the oil line. If a metal hopper is used for filling, the metal funnel must also be grounded.

 

 

 

Anti-leakage

No.

Compliance evaluation

Note

1

The pipelines and equipment in the workshop must be effectively sealed to prevent the material from running, running, dripping and leaking, and to prevent unorganized rows.

 

 

 

2

Check equipment, pipes, packaging containers, etc. regularly to avoid flammable liquid leaks due to impact, vibration, corrosion, etc.

 

 

Fiber Optic Side Glow Cable also known as Side Glow, Side Lit, or Lineal light cable is made from stranded or Solid core Polymer with a clear heat shrink jacket. Our stranded Sideglow cable is designed for tighter turns and longer runs, which is suitable for installation indoors or out. They are most often used to provide light lines in paving or stair fronts or for illuminating around the perimeter of swimming pools. Also Stranded is best in wet locations.
