A major operational challenge for the FDNY during cold weather is frozen hydrants caused by freezing temperatures. To prevent water from freezing in these hydrants across the city, the FDNY has specialized thawing apparatus trucks in each of the five boroughs. | New York City Fire Department (FDNY)

Retired Firefighter Brendan Ielpi was just four months into his career with the FDNY when he responded to the World Trade Center on 9/11/2001. That day, he lost his brother, Jonathan Ielpi of Squad 288. As the 24th anniversary of September 11th nears, we promise to #NeverForget Jonathan and the other 342 members who died that day. | New York City Fire Department (FDNY)
