FCC Technician Exam Question Of The Day (T0B01)

Q) When should members of a tower work team wear a hard hat and safety glasses?

A) At all times when any work is being done on the tower

NJ2X Notes:
Gravity is always present and towers involve heights.  This means there is an ever present risk of objects falling while working on a tower.  Hard hats and safety glasses help mitigate the risk of injury.
