What is the definition of an accident disability for a police officer who slips and falls on wet pavement?

applied this same definition to two more injuries in Matter of McCambridge v. McGuire, 62 N.Y.2d 563, 479 N.Y.S.2d 171, 468 N.E.2d 9. Although recognizing that "[n]ot every line of duty injury will result in an award of accident disability," we concluded that the petitioners in that case--one slipping on wet pavement as he was entering a patrol vehicle on a rainy day, the other losing his balance and falling while getting up from a desk--had both suffered accidental injuries as a matter of law. Crucial to our holding was that in each case "there was a precipitating accidental event * * * which was not a risk of the work performed" (id., at 567-568, 479 N.Y.S.2d 171, 468 N.E.2d 9).
