Safety Recommendations R-07-17 through -22

************************************************************

The National Transportation Safety Board makes the following
recommendations to the Chicago Transit Authority:

Correct all safety deficiencies identified by the Regional
Transportation Authority in its most recent and future
safety inspections and reviews, regardless of whether those
deficiencies are labeled as "findings, "observations," or
some other term. (R-07-17)

Examine all of the elements in the American Public
Transportation Association's "Standard for Rail Transit
Track Inspection and Maintenance" and incorporate all
appropriate elements of this standard in your system safety
program. Specifically, include the regular use of track
geometry vehicle inspections and the inspection of rail for
internal defects in your system safety program. (R-07-18)

Evaluate all territories to determine the number of
inspectors and the amount of time needed to ensure that
adequate track inspections are conducted, and implement
appropriate changes. (R-07-19)

Schedule as a priority the maintenance oversight workshop
and the training course that the Federal Transit
Administration plans to develop for track inspectors and
supervisors that will address the unique demands of track
inspection in the rail transit environment. (R-07-20)

Perform a comprehensive computational study of the existing
ventilation system using various fire and smoke scenarios to
identify potential deficiencies, and make improvements to
the ventilation system and smoke removal procedures based on
the findings of the study. These actions should address
reinstalling fan 108 and replacing unidirectional fans
(including fan 133) with dual direction fans as needed. (R-
07-21)

Examine and improve, as necessary, your ability to
communicate with passengers and perform emergency
evacuations. (R-07-22)
