Between rushing into burning buildings, assisting the sick and injured, and generally being stand-up community members, 12 Boston firefighters found time last week to strip down to their suspenders in the name of charity.

The muscular dozen grace the second annual Boston Firefighters Burn Foundation calendar. At a “Turn Up the Heat” launch event last Thursday, hordes of attendees, mostly young women, packed the Royale nightclub in downtown Boston as ’80s music blasted away.

Proceeds from the 2016 calendar will help the Burn Foundation “ease the suffering and hardships of burn victims and their families.” Among the most vulnerable of their beneficiaries are the children at the Shriners Hospital for Children.

Theron Holder doesn’t have far to travel from his Bowdoin-Geneva home to his Ladder 7 station in Dorchester. The 35-year-old December calendar-closer is a repeat figure, having nailed down July in the calendar’s inaugural year. Taking part again was an easy decision, he said, even though “we’re never gonna hear the end of it.”

Holder spends any chance he can helping out with the foundation. “I realize that it’s for the greater good, something that we can do to give back to the children,” he said.

The Burn Foundation aims to comprehensively care for victims, whether that means paying bills if they are unable to work or funding private rooms for burned children, who are often extremely uncomfortable with being seen in their conditions. It has covered the $150,000 for Physical Therapy and Occupational Therapy rooms at Massachusetts General Hospital, said foundation treasurer Phil Skrabut.

Taking on a calendar month means more than amping up their workouts and scrimping on food, the firefighters said. They each commit to at least two other charitable events to sell the calendar and spend time with young burn victims outside of the hospital.

For the kids, “it gets them out and used to being looking at,” Skrabut said, adding that it is often such a crucial part of the children’s well-being that it is incorporated into their physical therapy programs.

“Those kids are heroes to us,” said Alector Tavares, representing August 2016. The son of Cape Verdean immigrants, Tavares, 31, has a background of military service, which seemed no more dangerous to him than growing up in a tough neighborhood.

Firefighting is an incredible adrenaline rush, said Tavares, but the calendar is a different beast. “We get butterflies. You get nervous,” he admitted.

Many of the firefighters are still relatively new to the job, just a few years in. But, to a man, they said this is their career for life, even after being paraded on stage in front of cheering women for the cause.

Michael Kelly, 32, always wanted to be a firefighter. Now with two years on the fire service under his belt – after four years in the Navy – the Adams Street native is clocking in with what is likely his only time on the calendar. 

“I thought it’d be cool to look back; I looked half-decent,” said Kelly, who appears as Mr. January. He may let himself go now, he joked.
