Two construction workers died, and a third was injured, in two separate accidents on the same day in Manhattan. NY1's Lori Chung filed the following report.

A deadly fall brought work at the site of the Manhattan West development to a standstill after two men tumbled out of a bucket lift to the ground below.

"One of them hit face forward, and the other person just fell on his side," said Christopher Gamboa, a construction worker. "Once you saw the other guy fall, you already knew he was dead. He fell straight on his face."

Video shows the moments after the accident at the 62-story mixed-use building going up at 9th Avenue and 33rd street.

EMS crews rushed one victim to the hospital with head and body trauma. The other was pronounced dead at the scene.

Christopher Gamboa works at a site across the street.

"I was thinking about his family, mostly, of everything. He was supposed to go home today," he said.

The victims were both 45 years old. Witnesses say both men appeared to be wearing safety harnesses but may not have had them secured.

"I saw him that he got the harness on, but I don't know if he got attached to something," said Freddy Gamboa, a construction worker.

It happened just hours after another fatal fall in Lower Manhattan Thursday morning. Police say Juan Chonillo fell through an open hole and dropped 27 stories to his death at a construction site on Maiden Lane. According to relatives, the 43-year-old father of six was supporting family in Ecuador. 

"He was working here two years," said Angel Munoz, the victim's cousin. "He was a carpenter."

As for this accident, Tishman Construction is the company behind this job. A spokesperson released a statement, saying, "We are deeply saddened by this terrible tragedy and we are actively cooperating with all relevant agencies to investigate the matter." 

But one workers' advocate says the city should do more to increase safety at these job sites.

"That’s why we’re all fighting for the 1447 safety bill to be passed into law next week to protect workers so they get the proper training on the safety equipment that they’re issued if they‘re issued it, you know, they know how to use it, where it should apply. That’s what saves lives," said Anthony Fagiolo of the NYC Community Alliance for Workers Justice.

That bill would require at least 40 hours of safety training for construction workers at sites like this one, which is no stranger to deadly mishaps. Back in June, a 62-year-old worker also fell to his death here.
