BROOKLYN - The deadline to apply for the FDNY's firefighter exam is tomorrow, and the department is particularly interested in African-American and female applicants. Fire Commissioner Salvatore Cassano says so far, 48 percent of the applicants have been people of color and 7 percent have been women, which is more than ever before, but Cassano says he wants to get these numbers even higher. The FDNY held about 6,500 recruiting events across the city over the past year and a half. Regina Wilson, the president of the United Women Firefighters, says that is how she started her FDNY career in Brooklyn."Someone reached out to me and said to me, 'Listen, there are not a lot of women and not a lot of African-Americans,'" she says. "And I saw that as a challenge, and I've never regretted it ever since."
