11.2 Add the following paragraph in the
Access section: An internal ladder

■ Where towers are installed on an elevated grillage or piers, it is
often difficult to get to—and through—the access door conve-
niently. This platform provides easy, safe and comfortable access
to that door. It also extends beyond the door to provide ready
access to the optional Control System. See drawing on page 12.
Outside the tower, stainless steel platform material is not normal-
ly considered necessary. If you air quality is sufficiently poor to
warrant stainless steel, change the specification wording accord-
ingly.
NOTE
OSHA and other concerned authorities are in the process
of developing guidelines regarding the safety procedures and
protective equipment that should be provided maintenance per-
sonnel who are required to go inside cooling towers. We feel it
advisable to provide for as much maintenance as possible from
outside the cooling tower and, to that end, offer such options as
Guardrail and Ladder—pg 11, Ladder Extension—pg 11, Ladder
Safety Cage—pg 11, Access Door Platform—pg 13, and Motor
Out of the Airstream—pg 18. Such interior convenience options
as Plenum Walkway—pg 13, that are offered are not meant as
an invitation to perform inside maintenance. They are intended
solely to maximize the comfort and safety of maintenance per-
sonnel during the performance of any inside work may become
necessary.
