A 22-year-old man was hospitalized Friday after falling about 30 feet from a construction site in northern Forsyth County.

It was the second such incident public safety officials responded to in a three-day span last week.

The man, whose identity has not been released, hurt his upper body, back and legs, Forsyth County Fire Capt. Jason Shivers said.

Fire Lt. Greg Chapman said emergency personnel arrived about 2 p.m. at 3650 Henderson Road.

"We found him lying on his stomach moaning," Chapman said. "He fell approximately 25 to 30 feet off the roof of a house under construction."

Chapman said an ambulance to the man to a field on nearby Pilgrim Mill Road. From there, he was flown to Grady Memorial Hospital in Atlanta.

Chapman said it appeared the man may also have suffered trauma to his head.

Shivers said mishaps at construction sites are not rare.

"Twice in a week is somewhat unlikely. However, falls from roofs, ladders or scaffolding are not uncommon," he said, adding nail gun injuries and insect stings often are a problem on job sites.

Shivers said the most common outdoor construction incidents involve dehydration and heat exhaustion.

"That's certainly very common in the Atlanta area throughout the summer months for construction workers and landscapers," he said.

On Wednesday, a 27-year-old man was hospitalized after he fell about 30 feet from scaffolding at a construction site on Brumby Lane off Windermere Parkway.

Shivers said the man, whose identity also has not been released, appeared to have suffered "traumatic injuries."

Shivers urged construction workers to follow Occupational Safety and Health Administration guidelines when on a site and cautioned those working on their own homes.

"For homeowner use, they should never work alone and only climb ladders to the point in which the ladder is safe," Shivers said. "Don't go beyond the top rung recommended for climbing."

He said those using ladders should also make sure they are climbing at the ladder's recommended angle.

Shivers also said those working outside should drink plenty of fluids, even in the cooler fall months ahead.
