Above-ground storage tanks are an integral and invaluable component of numerous industries, storing everything from water to hazardous chemicals. However, these tanks can be susceptible to lightning strikes, posing significant risks to their structural integrity, the safety of their contents, and the well-being of those working in their vicinity. Therefore, implementing a robust lightning protection system becomes a vital aspect of maintaining safe and reliable above-ground storage tanks.
In this guide to lightning protection systems for above-ground storage tanks, we’ll delve into the importance of these protective measures, explain how they function, and discuss the benefits of engaging with a professional company specialising in lightning protection. By understanding and prioritising this facet of tank maintenance, you can significantly reduce the risks associated with lightning strikes and ensure that your tanks continue to perform safely and efficiently for years to come.
The Need for Lightning Protection Systems for Above-Ground Storage Tanks
Lightning is a prevalent and unpredictable phenomenon that can have devastating effects on industrial facilities, particularly above-ground storage tanks. The ramifications of a lightning strike on a tank can include:
1. Structural Damage: The intense energy transferred during a lightning strike can cause critical damages to a tank’s structure, leading to leaks, cracks, or severe deformations.
2. Fire and Explosion: When tanks store flammable liquids or gases, a lightning strike can ignite vapours, potentially resulting in fires or explosions.
3. Electrical Component Failure: Sensitive electrical components, such as monitoring systems, pumps, and valves, are susceptible to damage or failure during a lightning event.
4. Environmental Hazards: Leaks or spills caused by tank damage can lead to contamination of surrounding soil and water systems, leading to environmental pollution.
5. Personnel Safety Risks: Workers in proximity to struck tanks can be exposed to potentially life-threatening hazards, such as explosions or the release of hazardous substances.
How Lightning Protection Systems Work for Above-Ground Storage Tanks
Lightning protection systems are designed to divert the electrical energy of lightning strikes safely away from storage tanks. They primarily consist of the following components:
1. Air Terminals: Strategically positioned on or above the tank, these metallic devices, commonly known as lightning rods, intercept lightning strikes.
2. Conductor System: This network of metal cables forms a pathway for lightning strike energy to flow from the air terminals towards the grounding system.
3. Grounding System: Anchored into the earth, this system safely dissipates the lightning energy, minimising the risk of damage to the tank and surrounding environment.
4. Equipotential Bonding: By electrically connecting conductive components, such as valves and pipes, this measure ensures equal voltage levels throughout the system, reducing the risk of electrical arcing and equipment damage.
Best Practices for Implementing Lightning Protection Systems
To ensure the optimal performance of your lightning protection system, consider the following best practices:
1. Compliance with Regulatory Standards: Install a lightning protection system that adheres to established industry standards, such as Australian/New Zealand Standard AS/NZS 1768 and National Fire Protection Association (NFPA) 780.
2. Comprehensive Risk Assessment: A professional risk assessment can help identify the specific lightning hazards associated with your facility and inform the design and installation of an appropriate protection system.
3. Inspection and Maintenance: Regularly inspect and maintain your lightning protection system, verifying the integrity of grounded connections, cables, and terminals to ensure optimal performance during a lightning event.
4. Incorporating Surge Protection: To safeguard sensitive electrical components such as monitoring systems and control equipment, including surge protection devices within your overall lightning protection strategy.
