lightning arrestors on oil storage tanks

**Lightning arrestors** on oil storage tanks are critical safety devices used to prevent fires and explosions caused by direct lightning strikes or induced voltage surges. While some experts argue that large steel tanks can dissipate charge naturally, industry standards and regulations (such as those in Ohio for urbanized areas) often mandate the installation of **lightning arrestors** or comprehensive protection systems for petroleum storage.

Protection strategies typically involve two main approaches:

* **Lightning Protection Systems (LPS):** Traditional systems use air terminals (lightning rods) to intercept strikes and ground the current, often requiring specific spacing (e.g., rods spaced no more than 5 meters apart) and low-resistance grounding (typically under 10 ohms).
* **Lightning Prevention Systems:** Advanced technologies like the **Dissipation Array System (DAS)** aim to prevent strikes entirely by reducing the local electric field below the threshold for streamer formation, while **Retractable Grounding Assemblies (RGA)** ensure low-impedance bonding between floating roofs and tank shells to prevent arcing.
* **Flame Arresters:** Often installed on tank vents and breather valves, these devices allow vapor pressure equalization while physically blocking flames from entering the tank if an ignition source is present.

Proper implementation requires **equipotential bonding** of all metallic components, including floating roofs and piping, to prevent dangerous potential differences that could lead to sparks.
