Technician crouching beside insulated pipes — Nuclear maintenance ultrasonic pipe measurement

A crouching technician in navy coveralls wears a white hard hat, safety glasses, a yellow earplug and blue gloves. He places the ultrasonic probe on a large insulated pipe beneath a metal elbow and a second pipe. The black detector shows a gridded screen on a hard case beside a white couplant bottle. Green supports carry the pipes, and yellow guardrails border the industrial walkway.
