[BNC-all] BRK Evacuation Summary 7/9/09

[Kuhn, Jeffrey G]

All,

 

Today's building evacuation was caused by a component failure in the air
pressurization portion of the building's fire protection system. The
system affected is normally filled with air in order to provide freeze
protection to sections of the piping exposed to winter temperatures.
When the component failed this afternoon, water was permitted to flow
into the pipe triggering the evacuation alarm. At no time was the
building without fire protection.

 

Purdue's FES has completed repairs to the system and it is operating
normally. As always, any evacuation alarm should be treated as real. We
do not conduct tests of the Birck emergency systems without prior
communication.

 

We apologize for any inconvenience today's evacuation may have caused
and appreciate your patience and understanding in this matter.

 

Regards,

 

Jeff Kuhn
