SOHO, Manhattan (WABC) --

Six people were hurt after scaffolding collapsed into the street in Lower Manhattan Sunday morning.

The incident happened just after 11:30 a.m. near the intersection of Broadway and Prince in SoHo.

Pictures from the scene show wooden planks all over the street, and FDNY firefighters at the scene.

FDNY officials said "we're absolutely lucky" there aren't more injured in this busy neighborhood. There is a subway stop right at the intersection, and the area was packed with people out enjoying their Sunday morning.

Investigators said strong wind is to blame for the collapse. A piece of plywood "acted like a sail" and blew the whole rig down.

Cellphone video shot moments after the collapse shows bystanders running in to help people trapped:

Two people had to be rescued from under the rubble. They and three others were taken to the hospital to be treated for minor, non-life threatening injuries.

The New York City Health Department announced the community cluster of the disease Friday. All seven cases have been confirmed in the last seven days. The area impacted is the Lenox Hill neighborhood, which runs from East 60th Street to East 77th Street.

Four of those infected with the disease are still hospitalized, two have been discharged and the person who died was in his/her 90s and had significant underlying health conditions.

Legionnaires' disease is caused when water tainted with Legionella bacteria is inhaled into the lungs. It's a severe form of pneumonia in which the lungs become inflamed due to infection.

The health department said symptoms include fever, cough, chills, muscle aches, headache, fatigue, loss of appetite, confusion and diarrhea. Symptoms usually appear two to 10 days after significant exposure to Legionella bacteria.

In response, Councilman Ben Kallos is proposing a law requiring time limits.

"I put in a proposal that would give landlords three to six months to do the work. They wouldn't be able to stop that work at any point for more than seven days. And if they don't do the work, the city needs to step in and do the work ourselves and make bad landlords pay," Councilman Kallos said.

Representatives from the FDNY, along with firefighters from Rescue 1 and Engines 53, 91, 58, 76, 44 will be on hand to receive a Proclamation from Council Member Ben Kallos at City Hall.

81-year-old Jim Duffy was trapped on the fifth floor of an apartment building on East 93rd Street that quickly became engulfed by fire.
