Petitioner, a substitute groundskeeper for a public school district, was operating a leaf blower on a grassy area adjacent to a school parking lot when he lost his balance and fell off the parking lot curb. Respondent determined that petitioner did not suffer an "accident" within the meaning of the Retirement and Social Security Law and, accordingly, denied his application for accidental disability retirement benefits. We confirm. An "accident" is a sudden and extraordinary event that does not result from an activity performed in the course of ordinary employment duties ( see, Matter of Talerico v. McCall, 239 A.D.2d 863). Here, it is undisputed that petitioner was performing ordinary employment activities at the time of his fall. In view of this, as well as petitioner's failure to establish that his fall was occasioned by anything other than his own misstep, we find no reason to disturb respondent's finding that petitioner did not suffer an "accident". ( see, Matter of Gallello v. McCall, 247 A.D.2d 693; Matter of Minchak v. McCall, 246 A.D.2d 952).
Mikoll, J. P., Crew III, White, Spain and Carpinello, JJ., concur.
Adjudged that the determination is confirmed, without costs, and petition dismissed.
