germent to personnel. If your electrical system contains a disconnect
switch, lock it out until the period of exposure to injury is over.
The top of the tower is not a working surface. Do not stand, sit or
walk on top of the tower. Use an appropriate ladder adjacent to the
tower whenever you perform any maintenance activity on the tower’s
upper surfaces.
