This paper deals with the importance of proper basic thermal imager settings for thermographic surveys, and will also show how improper thermal imager settings can result in potentially dangerous outcomes in regard to plant equipment, personnel safety, and property. Examples of shoddy inspections using improper thermal imager settings will also be shown. This paper will further discuss the importance of possessing adequate knowledge and experience for the application and equipment being inspected to effectively detect discontinuities. It will also briefly highlight the recent changes to the American Society for Nondestructive Testing’s Recommended Practice No. SNT-TC-1A (ASNT 2016c) in regard to thermal/infrared inspections, which now addresses this important issue.
