Dive Brief:

• What should have been another routine day in a five-year water-pipe replacement project took a bizarre and tragic turn when a blade on a circular saw being used to slice through pavement came off its hub and struck a pedestrian down the street from the worksite.
• The woman received cuts to her right arm and leg and was taken to a hospital with what police termed a "major injury." Her condition was unreported Tuesday evening.
• Officials said it appeared that the 3-foot blade hit a curb when it came off the saw, bounced about 10 feet in the air and hit the woman, who was unable to get out of the way.

Dive Insight:

The pipe replacement is an ongoing project in the Hell's Kitchen area on the west side of Manhattan. It was unclear Tuesday whether the crew worked for the city or a contractor and who owned the saw. The accident is the kind of event that likely sends shivers down the spines of liability managers and insurance brokers.
