Three workers were seriously injured in an apparent construction accident Friday morning after they fell about 25 feet from a ladder at an apartment complex in Norwood, officials said.

Two of the workers sustained “critical injuries,” and the other was seriously injured but expected to survive, according to Joseph O’Malley, a spokesperson for the Norwood Fire Department.

Norwood fire received “multiple 911 calls” at around 11:03 a.m. for an accident at The Commons at the Windsor Gardens, an apartment complex, according to O’Malley. Firefighters found three men injured at 401 Buckminster Drive, George Morrice, chief of Norwood fire, said in a statement.

One of the workers was taken in an ambulance to Norwood Memorial Airport where he was transported via a MedFlight helicopter to Massachusetts General Hospital. Another was taken to Boston Medical Center in an ambulance from Walpole Fire, the statement said. The third worker was taken to Good Samaritan Medical Center with “injuries that are believed to be non-life-threatening,” the statement said.

It was not immediately clear what work the men were doing at the complex, O’Malley said.

Firefighters found a “chaotic scene” when they arrived at the apartments — several ladders were set up around the building, he said.

A building inspector and Occupational Safety and Health Administration officials were at the scene.

Ted Fitzgerald, a spokesman for the US Department of Labor, which oversees OSHA, confirmed via e-mail that OSHA is investigating.

“The purpose of an OSHA inspection is to determine whether or not an employer is in compliance with the workplace safety or health standards that apply to that particular type of workplace or work being done,” Fitzgerald said via email. “As part of that process, OSHA inspectors will gather all pertinent information needed to make a determination.”

He added that OSHA has up to six months to complete an inspection.

“It’s too early to estimate a completion date for this inspection,” Fitzgerald said.

The Norwood case follows a string of tragedies at construction sites across the region since February.

On Feb. 24, two workers on High Street in downtown Boston were fatally struck by a truck that knocked the men into a 20-foot hole in the road.

About a week later in early March, a worker was killed and a second was critically injured in Cambridge when a section of concrete stairwell inside a city-owned parking garage collapsed during renovation work.

Those tragedies were followed by another accident in early May in Newton, where a worker died after a concrete wall fell on him while he was working in the foundation of a house undergoing renovation in the city’s Newton Highlands section.
