3.1.2 Pendulum (Swing) Falls

Swing fall hazards must be minimized by anchoring directly above the user's work space. The force of
striking an object in a pendular motion can cause serious injury. Always minimize swing falls by working as
directly below the anchorage point as possible.

3.1.3 Rescue and Evacuation

The user must have a rescue plan and the means at hand to implement it. The plan must take into account
the equipment and special training necessary to effect prompt rescue under all foreseeable conditions.
