Need some Brain Storming

Hey All,

I have a customer that was renovating a 3 story apartment building. 
During 
the renovation it was found that kids were climbing up the fire escape 
ladder to the roof and having a party, not to mention the vandalism.  So a

decision was made to cut off the ladder at 112 feet above the ground to
stop 
the action.

It was decided that when the renovations were complete they would install
a 
different ladder that would be in a UP position but when needed would be 
lowered from the landing by the person in need of escape.

Well that time has come and when this was proposed to the City Fire 
Department the FD said they will not allow this because the person that is

trying to escape may be afraid to use the ladder of this kind.  And that
the 
only thing they will approve is the original ladder bolted to the wall all

the way to the ground.

Now I have been asked if I can come up with some way to stop or at least 
deter activity UP the ladder to the roof.

Anyone have any thoughts or experience with this kind of issue????

Thanks in advance for any suggestions.
