During Lamping, how many people typically perform the procedure?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Lamping is a sewer inspection task done inside a manhole or pipe to visually assess conditions with a portable light. It requires a two-person team because safety and communication are essential in confined spaces. One person handles the light and observes the interior, while the other stays outside or at the rim to monitor air/gas conditions, assist with equipment, and be ready to help rescue if something goes wrong. This arrangement helps prevent entrapment and ensures a quick, coordinated response if an hazard appears. For these safety reasons, the typical number of people involved is two.
