Taken over a three year period, the powerful images capture the brave men and women serving in fire departments across New Jersey.
Sidelined due to injury, photographer and New Jersey firefighter David Hernandez decided he wanted to document the daily life of his former colleagues.
The images highlight the dangers of the job but also reinforce the camaraderie among firefighters risking their lives going toe-to-toe with mother nature.
He said: “Whether you call it historical documentation or something else, I feel the responsibility to record what my brothers and sisters are doing.
“Shooting fires is like shooting sports. If you haven't played the sport, it is harder to anticipate when things are going to happen.
"Since I've fought fires, it's easy to understand what will happen next.”
The 30-year-old became a voluntary fireman in New Jersey in 2000 and has been taking photographs of fires since 2007.
However, in 2015 he sustained a serious injury to his back during a fire in which he slipped and fell down a staircase.
He said: "This past December, I decided to change my focus on photographing firefighters.
"It was hard taking the news that I can't go back to firefighting - something I've done for my entire adult life so far."
David, whose stepfather was a firefighter, started his love affair with the profession at the age of 14 when he enrolled to become a junior firefighter.
Forced by his injury to remain a spectator, he decided to combine his love for firefighting with the media skills learned during his communications degree by creating an online docu-reality series in which he shadows his former colleagues in New Jersey.
He said: “The pilot season has had nearly 3.5 million views on YouTube. We started to film another season, but I was injured a couple months into filming.”
Despite his injury David is determined to continue to document firefighters and the incredible work they do.
He said: “Fifty years from now I want someone to flip through a book and know the courage and sacrifice that people were making in our time.
"I want the impact of these images to be timeless. I love that every time someone sees the photos for the first time they say ‘wow!' and look closer at the image.”
