A Security System For Doors And Windows installed by builders in newly constructed buildings and by rehabbers in older structures in the Chicago area has presented some significant challenges for firefighters, among them egress in an emergency and forcible entry. The system, known as VPS (Vacant Property Security) in this area, first appeared on Chicago's West Side about eight months ago. It greatly reduces theft of building materials, and workers can lock themselves in the building, providing a safer work environment. The system is also being used by local community groups to secure problem vacant buildings and by drug dealers to keep the police at bay. In some instances, the system has been found on lower floors of occupied apartment buildings.
