Tank Lightning Protection

Above-ground industrial tanks play a crucial role in numerous industries, storing critical materials such as water, chemicals, and petroleum products. Ensuring the integrity and safety of these industrial tanks is of paramount importance. One often overlooked yet vital aspect of risk management for industrial tanks is the implementation of lightning protection systems. These systems protect tanks from the damaging effects of lightning strikes, greatly reducing the risk of catastrophic safety incidents and equipment damage.

In this article, we will delve into the importance of industrial tank lightning protection, exploring the potential consequences of lightning strikes on tanks and the benefits of robust lightning protection systems. We will also discuss the various techniques and equipment available for lightning protection that cater to specific industry and tank requirements. With our extensive expertise in tank design, installation, repairs, and maintenance at ATM Tanks, we are committed to enhancing the safety and integrity of industrial tanks across Australia and the Pacific.

Understanding the Risks Associated with Lightning Strikes on Industrial Tanks

1. Ignition and Explosion: The most severe risk associated with lightning strikes on industrial tanks is the potential ignition of flammable contents, leading to fire or explosion. This can cause significant damage to the tank and its surroundings, as well as pose a major safety hazard for personnel and the environment.

2. Structural Damage: Direct lightning strikes can cause physical damage to tanks, affecting their structural integrity and potentially leading to leaks or failure. This damage can also extend to tank ancillaries, such as valves and instrumentation, further impacting the functionality of the tank.

3. Electrical Damage: Lightning strikes generate strong electrical currents that can propagate through conductive materials like tank walls and connected electrical systems. This can result in electrical damage or malfunction, which may disrupt operations and require costly repairs.

4. Downtime and Reputation: Lightning-induced incidents can lead to business interruptions, resulting in downtime and loss of income. Additionally, the occurrence of a significant safety incident can damage a company’s reputation and overall credibility in the industry.

Key Components of an Effective Tank Lightning Protection System

1. Lightning Rods: Lightning rods, or air terminals, are metal structures mounted on or near the tank, designed to intercept and direct lightning strikes safely to the ground. By acting as a preferential strike point, lightning rods help protect the tank from direct strikes and their damaging effects.

2. Grounding Electrodes: Proper grounding is critical for safe and effective lightning protection. Grounding electrodes are used to create a low-resistance electrical path between the lightning protection system and the earth, allowing lightning energy to be safely dissipated.

3. Surge Protective Devices: These devices safeguard electrical and electronic equipment within tank systems by diverting or blocking transient surges in voltage or current induced by lightning strikes. Properly installed surge protective devices help prevent electrical damage and equipment malfunction.

4. Interconnecting Components: Interconnecting components, such as conductors, connectors, and fittings, are used to safely route lightning currents between air terminals, grounding electrodes, and surge protective devices to form a complete lightning protection system.

Implementing Lightning Protection Measures for Industrial Tanks

1. Risk Assessment and Design: The starting point for implementing lightning protection is to conduct a risk assessment to identify potential hazards and establish the best approach to mitigate these risks. The resulting protection plan should then incorporate the key components discussed above, tailored to the specific tank type and operating conditions.

2. Compliance with Standards: An expert consultant should ensure that the chosen lightning protection system complies with relevant industry standards and guidelines, such as the Australian Standard AS/NZS 1768:2007 or the International IEC 62305 series. Compliance with these guidelines ensures the effectiveness and robustness of the system.

3. Installation by Specialists: For the lightning protection system to function effectively, qualified professionals must perform the installation, as improper installation can compromise its safety and efficiency.

4. Regular Inspection and Maintenance: Performing regular inspections and system maintenance ensures that the lightning protection system remains in optimal condition and continues to provide adequate safety measures.

Enhancing Safety and Compliance with Lightning Protection Systems

1. Asset Protection: An effective lightning protection system minimises the risk of damage to industrial tanks, as well as related infrastructure and systems, ensuring the longevity and functionality of your assets.

2. Personnel and Environmental Safety: By mitigating ignition risks and reducing the potential for explosions or fires, lightning protection systems contribute to a safer working environment for personnel and protect the surrounding ecosystem from potential hazards.

3. Regulatory Compliance: Installing lightning protection systems for industrial tanks as per the relevant guidelines and standards ensures compliance with industry regulations and reduces the risk of legal or financial repercussions.

4. Business Continuity: Investing in lightning protection helps to maintain business operations and reduce unforeseen downtime in the event of a potential lightning-induced safety incident.
