received instruction in the safe operation of the specific system.

1.6

Where suspended scenery components are moved by
guided hand-pulled ropes or wire ropes, the weight of
the components shall not exceed a balanced load by
more then forty pounds (40 Ibs.). Should this not be
the case, the scenery component shall be balanced
with a counterweight to bring the imbalance to less
than forty pounds. Exceptions to this rule may be
taken only during load in and strike of scenery when
proper precautions are taken.

1.7

Buffering or shock absorbing devices, which reduce
hard contact between the counterweight carriage and
the upper and the lower stops, shall be installed.
Hard contact is a sudden (or uncontrolled) contact
with the upper or lower limits of the travel of the counterweight carriage.

1.8

The installed counterweights shall be secured against
falling from the counterweight carriage during
operation.
The operating gallery and catwalks shall be
equipped with safety railings and toe boards.
The loading gallery/platform shall have a sign stating counterweight storage limit in Ibs. per sq. ft. and
not to exceed the height of the toe board.
Counterweight stored on the deck of the gallery/
platform shall not exceed seventy-five percent (75%)
of the total deck area. The area of the deck immediately in front of the counterweight carriages shall be
