A probationary firefighter has died in the line of duty, the FDNY announced Friday.

Fire Commissioner Daniel Nigro said 31-year-old Vincent Malveaux suffered a medical episode during a training exercise at the FDNY Training Academy on Randalls Island at approximately 10:30 a.m. Thursday.

According to Nigro, Malveaux was three-quarters of the way through a functional skills training course - training that involves typical firefighting tasks - when he became sick and passed out.

He was prononuced dead Friday morning at Harlem Hospital.

"This is a heartbreaking loss of a young man who chose a life of brave service to others, first providing outstanding emergency medical care as an EMT in the Bronx and then training to be a New York City Firefighter," Nigro said in a statement. "Our entire Department mourns the passing of this heroic individual who dedicated himself to saving lives. Our thoughts are with his family, our EMTs who worked closely beside him, and his fellow Probies."

The FDNY said Malveaux was in his sixth week of firefighter training after being sworn into the probationary firefighter class in late October. He was one of more than 300 probational firefighters undergoing the training, which lasts 18 weeks. He had previously served as an FDNY EMT in the Bronx for four years.

"He is the first member of his family to serve with the department. Very proud to have served as an EMT and now a firefighter," Nigro said at the hospital Friday. "Just a very sad event at a difficult time of year."

The men and women of Malveaux's academy squad saluted in silence as his body was loaded into an ambulance outside Harlem Hospital Friday.

Purple and black bunting was also draped outside the FDNY Fire Academy in his honor.

Malveaux is the 1,154th member of the FDNY to died in the line of duty.
