Terry Andres, who was 62 and from Virginia Beach, Virginia, was killed at the airport as he prepared to go on holiday with his wife, local media reported.
Mr Andres' daughter was quoted as saying he would have celebrated his 63rd birthday later in January.
Mr Andres was said to have served since 2004 with the Oceana Volunteer Fire Department, where he was remembered fondly: "He was well liked and respected for both his dedication to being a volunteer as well as his professional approach to his job as a support tech," the department was quoted as saying.
"We mourn his passing as we do all the victims of the senseless attack in Ft. Lauderdale."
Mr Andres' wife was not reported to have been injured.
A gun taken from the Fort Lauderdale shooting suspect when he underwent a psychological evaluation last year was returned to him, police in Alaska have said.
Anchorage Police Chief Christopher Tolley said it was not clear if this was the same gun used in the attack which left five people dead and six injured.
Police said the gun was returned to Esteban Santiago because he had not committed a crime.

A British great-grandmother was among the victims of the Fort Lauderdale shooting, according to reports.
Olga Woltering, who was in her eighties, was revealed as one of the five people killed in Friday's mass shooting at the airport when her church posted a touching tribute to her online.
The Catholic Church of the Transfiguration in Cobb County, Georgia, described Mrs Woltering as "charming" and "one of the most joyful, loving, caring and committed people".
The brother of the man suspected of carrying out the Fort Lauderdale airport shooting has questioned why Esteban Santiago was allowed to keep his gun after US authorities knew he had become increasingly paranoid and was hearing voices.
The 26-year-old reportedly had trouble controlling his anger after serving with the US National Guard in Iraq, and told his brother that he felt he was being chased and controlled by the CIA through secret online messages.
Speaking to FBI agents in Alaska, where he lived, Santiago had reportedly told them the government was forcing him to watch so-called Islamic State group videos.
When Santiago told agents at the FBI field office his paranoid thoughts in November, he was evaluated for four days, and then released without any follow-up medication or therapy.
"The FBI failed there," Bryan Santiago said, adding: "We're not talking about someone who emerged from anonymity to do something like this."
"The federal government already knew about this for months, they had been evaluating him for a while, but they didn't do anything."
The suspect in the Florida airport shooting chose to travel to Fort Lauderdale to carry out the attack which left five people dead, authorities have said.

Mr Piro continued that Esteban Santiago, 26, the suspect, was cooperating with investigators and was interviewed for several hours overnight.
