How often should an ASME container be visually inspected before filling?

The correct answer highlights the importance of ensuring safety and compliance in the usage of ASME (American Society of Mechanical Engineers) containers. Visual inspections are critical to identify any signs of damage, corrosion, or wear that could compromise the integrity of the container before it is filled. Performing a visual inspection prior to each filling allows for immediate risk assessment and helps to prevent potential hazardous situations that could arise from using a compromised container. This practice aligns with safety regulations and best practices in handling pressurized containers, ensuring reliable performance and safety for operators and the environment.

In contrast, specifying a time period such as every month, annually, or every 5 years does not adequately address the immediate risks associated with filling a container that may have developed defects since the last inspection. Ensuring that containers are inspected right before they are filled establishes a proactive approach to safety management that prioritizes the well-being of personnel and compliance with industry standards.
