When is it most critical to perform visual inspections on an AST?

• A. After installation
• B. During regular service
• C. Before and after significant weather events
• D. At periodic intervals as set by regulations

Answer: (C)

Performing visual inspections on an Aboveground Storage Tank (AST) before and after significant weather events is crucial because these events can lead to physical changes in the integrity of the tank and surrounding structures. Heavy rain, strong winds, or other extreme weather conditions can cause stress to the tank, potentially leading to leaks, structural failures, or other forms of damage that may not be present during normal operating conditions. Inspecting the tank in the aftermath of such events allows for the detection of any immediate issues that could pose a risk to safety or environmental integrity. While there are also important times to conduct inspections, such as after the installation, during regular service, or at periodic intervals mandated by regulatory agencies, significant weather events introduce unique risks that can rapidly affect the condition of the tank. Therefore, vigilance during these circumstances is particularly vital for maintaining safety and compliance.
