Visual Surveillance & Monitoring
“A visual inspection is hands-on and requires careful and close examination. The inspector should look closely at the members of connections and not just view them from a distance. Inspectors should use various measuring scales, and other hand tool to identify, measure, and locate areas of concerns. Boroscopes, flashlights, and mirrors bay be necessary to inspect areas of limited visibility. Weld gauges should be available to check the dimensions of weld beads. Critical areas should be cleaned prior to inspection, and additional lighting should be used when necessary”.[1]
