Have you ever wondered about the chain hanging behind fuel tanker trucks? It’s a crucial safety measure to prevent fires and explosions caused by static electricity. This article will explain in detail the function of fuel truck grounding chains, or more precisely, earthing chains, on tanker trucks.
Grounding chain on a fuel truck
When a fuel tanker truck moves, friction between the liquid fuel and the tank walls, along with contact with dry air, generates static electricity. Static electricity is an imbalance of electric charges on the surface of a material. This charge buildup poses a risk of electrical discharge, creating sparks and leading to fires or explosions, especially with flammable materials like gasoline and diesel.
How Grounding Chains Work
The chain hanging behind the fuel truck, usually made of highly conductive metal, acts as an earthing chain. It provides a path for the accumulated static charge on the tank to flow to the ground, neutralizing the charge and preventing electrical discharge. This significantly reduces the risk of fire and explosion.
The Importance of Grounding for Tanker Trucks
Grounding with fuel truck grounding chains (earthing chains) is not only important during transportation but also essential when pumping fuel into or out of the tank. In addition to chains, specialized grounding systems like RTR – Road Tanker Grounding (Earthing) are used to ensure absolute safety.
Conclusion
Fuel truck grounding chains – or earthing chains – are a simple yet effective solution for preventing fires and explosions caused by static electricity on fuel tanker trucks. Equipping and using grounding chains correctly is crucial for ensuring the safety of people, vehicles, and the environment.
