Why Tankers Have a Chain Hanging in the Back

tragedy. It does not require sophisticated maintenance, does not consume energy and its cost is minimal, but its absence could put thousands of lives at risk.

This example demonstrates how, in the field of engineering and industrial safety, the most effective solutions are not always the most complex. Sometimes, applying basic principles of physics—such as electrical conduction and grounding—is enough to solve potentially catastrophic problems.
Conclusion: an invisible but indispensable protection

The chain that hangs on the back of tankers is much more than a curious accessory: it is a key safety element that disperses static electricity before it can
