The FDNY will add 22 more names to a memorial for first responders who died of 9/11-related illnesses Friday — a somber reflection on the terror attacks’ ongoing impact as their 18th anniversary approaches.

The 22 FDNY service members all died over the last year and include 13 firefighters, two captains, two lieutenants, one chief, two EMTs, one paramedic and one doctor, the agency said in a release.

“This solemn wall is a poignant and permanent reminder of the sacrifice of all that responded on September 11th and toiled for weeks and months at the World Trade Center searching for the innocent lives taken that day,” Fire Commissioner Daniel Nigro wrote in a statement.

“Because of their dedication and bravery, each year the already staggering loss suffered by the FDNY continues to grow as illnesses claimed the lives of those who so bravely served our city.”

To date, more than 200 FDNY members have died of illnesses related to their heroic efforts on 9/11 and many didn’t start to feel the effects until years after the attacks.

Retired firefighter Kevin Bevilacqua, 53, was interviewed by The Post in May after he was diagnosed with brain cancer just last year.

“I was talking to a friend of mine the other night… ‘is this thing going to get us all?’ Throughout the years you’re wondering is your number going to be called,” Bevilacqua said at the time, adding he’s attended countless funerals in the 18 years since 9/11.

The memorial is located at FDNY headquarters in Brooklyn.
