Where should inspection of the overhead parts and supports be conducted from?

• A. A bosun's chair suspended through the roof vent after the tank has been gas freed
• B. From ladders or scaffolding
• C. From the very center of the tank bottom with a powerful sealed beam portable light
• D. The entry point or other observation points before entering the tank

Answer: (D)

Inspection of the overhead parts and supports should be conducted from the entry point or other observation points before entering the tank to ensure both the safety of the inspector and the integrity of the tank. This approach allows for a preliminary assessment of the overhead structures without putting anyone at risk during the process of entering the tank. It is crucial to identify potential hazards, such as corrosion, structural weaknesses, or any debris that could fall, thus prioritizing safety before engaging in more invasive inspection measures. In addition, this method facilitates a more comprehensive view of the overhead supports and other components since it can be combined with visual inspections using portable light sources. This helps assess if any further inspection or maintenance is necessary while maintaining safety protocols. Other options, while they might provide access to overhead parts, could compromise safety. For instance, inspecting from a bosun's chair entails potential risks if the tank has not been fully gas-freed or if the chair's setup is not adequately secure, which raises safety concerns. Ladders or scaffolding can provide access but may also introduce safety hazards, and inspecting from the very center of the tank bottom would limit visibility and may also involve dangers associated with entry into a confined space. Therefore, the chosen method of observation from entry points or other
