Abstract: Employees #1 through #7, of the New York City Fire Department, were engaged in a search and rescue operation at a fire in a NYC Housing Authority senior citizen apartment building in Brooklyn, NY. Employees #1 through #3, of the Forensic Engineering and Technology (FET) crew I-70, became trapped inside the common hallway on the tenth floor on the Exposure #4 side of the burning building. They transmitted a Mayday, and fire rescue operations went in after them. Employees #1 through #3 were found unconscious and lifeless, and were removed to other parts of the building. They suffered from smoke inhalation and were pronounced dead upon arrival at the hospital. Employees #4 through #7 all sustained burns that required hospitalization.
