DARIEN — The Occupational Health and Safety Administration has opened an investigation into the falling death of a construction worker on Nearwater Lane.

The worker died after an apparent fall from scaffolding at home construction site Monday.

Police received a 911 call at 12:51 p.m. about a contractor who had apparently fallen while working on the home.

Police, Darien EMS and Stamford EMS arrived at the scene to find an unconscious man at the rear of the home with “visible head trauma,” police said. No other workers or people on site witnessed the incident, but responders deduced that the man had fallen from scaffolding directly above the spot where he was found.

The man was taken to Stamford Hospital by Darien EMS, where he was pronounced dead.

OSHA spokesman Ted Fitzgerald said Tuesday that the Darien Police Department notified OSHA’s Bridgeport office of the death, and that an inspector was sent to the site.

The inspection will seek to determine if any workplace safety standards were violated, Fitzgerald said.

Investigators have not released the man’s identity, or said what company he worked for.

Nearwater Lane is one of the town’s busiest areas for construction. At least three homeowners have obtained demolition permits this year to build larger houses.

OSHA says that 4,679 workers were killed on the job in 2014. That’s an average of almost 90 a week or more than 13 a day.

Fatalities involving construction workers numbered 874. The leading causes of those deaths was falls, followed by electrocution, being struck by an object and being caught in or between something.
