How many people should be present above a manhole when an inspector is inside for safety during an emergency?

Having two people present above a manhole while an inspector is inside is crucial for safety during an emergency. This safety protocol ensures that there is adequate support in case something goes wrong. When only one person is present, they may not have the ability to provide immediate assistance if needed, especially in an emergency situation where quick action may be required.

With two people present, one can remain focused on monitoring the inspector's condition and the surroundings while the other can initiate emergency procedures or call for additional help if necessary. This arrangement significantly enhances safety because it allows for immediate response capabilities without leaving the inspector unmonitored. Having multiple individuals helps minimize risks associated with potential hazardous conditions, reinforcing the importance of teamwork during inspections.
