MUGGLIN, J.
Petitioner, a police officer for the Village of Port Chester, Westchester County, was dispatched to assist an elderly man who had fallen out of bed. As petitioner attempted to lift the man into bed, a throw rug on the floor slipped, causing petitioner to fall and be injured. The Hearing Officer denied his application for accidental disability retirement benefits on the basis that the incident did not constitute an accident within the meaning of Retirement and Social Security Law § 363. Respondent upheld the denial and this CPLR article 78 proceeding ensued.
In order for an injury to be considered accidental under the Retirement and Social Security Law, it must have resulted from "a `sudden, fortuitous mischance, unexpected, out of the ordinary, and injurious in impact'" (Matter of Lichtenstein v. Board of Trustees of Police Pension Fund of Police Dept. of City of N.Y., Art. II, 57 N.Y.2d 1010, 1012, quoting Johnson Corp. v. Indemnity Ins. Co. of N. Am., 6 A.D.2d 97, 100, affd 7 N.Y.2d 222; see Matter of Amadio v. McCall, 2 A.D.3d 1131, 1131). Crucial to such a finding is that the event precipitating the injury was not a risk of the work performed (see Matter of Amadio v. McCall, supra at 1132; Matter of Nedwick v. McCall, 308 A.D.2d 653, 653; Matter of Jonigan v. McCall, 291 A.D.2d 766, 766).
At the time of his injury, petitioner was performing routine duties as a police officer in going to the aid of a distressed citizen. That a throw rug might slip under petitioner's feet while he was performing these duties is both a risk inherent in the performance of his routine duties and not an unexpected event. Thus, substantial evidence supports respondent's determination that this incident was not an accident within the meaning of the statute (see Matter of Stevens v. New York State Comptroller, 299 A.D.2d 644).
