This from Larry Shapiro:
Northbrook units were called to 1751 W. Lake Cook Road in Deerfield before 11AM today for a worker that had fallen 15 feet into a concrete well alongside a building. Companies arrived to find a window washer that had been working over a steel grate that covered the space. An angle iron which supported one side of the grate gave way sending the worker down into the hole.
A TRT response was requested. Firefighters in the hole stabilized the patient and packaged him in a stokes basket while rope techs setup rigging to hoist him to ground level.
