RE: 7 World Trade Center
Class "E" Shutdown
Dear Lieutenant:
Please be advised that the Class "E" system for 7 World Trade
Center will be inoperable from Friday, 8/17/90, at 6:00 P.M.
until Sunday , 8/19/90, 6:00 P.M. This shutdown is due to the
"tying" in of additional floors into the base building system.
As a precautionary measure, firewatch patrol guards will be
stationed on each tenant occupied floor for the duration of the
shutdown (48 hours).
Should any questions arise, please feel free to contact me at
619-6569.
Respect fullYzy
