New York's first responders were given an unusual warning this week, a first since the Sept. 11 terror attacks: skip this year's in-person anniversary events. In a letter addressed to members of the FDNY, Fire Commissioner Daniel Nigro cautioned against the department's members attending anniversary events this year as the coronavirus pandemic continues to threaten the safety of everyone, especially retired members and families of 9/11 victims that are at a greater risk due to health and age. "From a health and safety perspective, the FDNY strongly recommends that our members forego participating in 9/11 gatherings and events this year," Nigro said. "However, the Department respects our traditions and will authorize certain events if currently accepted protective conditions can be adhered to." The commissioner outlined guidelines required for FDNY members sponsoring memorial events at or nearby FDNY facilities.
