What is the safest approach when working near overhead power lines?
a.Touch them to test if they are live
b.Lean ladders against them
c.Spray them with water
d.Maintain a safe clearance distance and assume all lines are energized

Workers should assume all overhead power lines are energized and maintain the required minimum clearance distance, which increases with voltage. Equipment such as cranes and ladders must be kept well away from lines. Contact with overhead lines is a leading cause of electrocution in construction.
