Circle Rubbish, which contracted with defendant Hunt's Point Terminal Market Cooperative Association to provide street cleaning services at the market, demonstrated that none of the situations in which a contractor of this type may be said to have assumed a duty of care, and thus to be potentially liable in tort to third persons, is present here ( see Espinal v Melville Snow Contrs., 98 NY2d 136, 140). There is no evidence that Circle Rubbish launched "a force or instrument of harm" ( Moch Co. v Rensselaer Water Co., 247 NY 160, 168 [1928]), that plaintiff detrimentally relied on the continued performance of Circle Rubbish's duties under its contract with Hunt's Point, or that that contract was comprehensive and exclusive and therefore gave rise to a duty on Circle Rubbish's part that displaced either owner's normal duty to maintain the premises in a safe manner ( see Palka v Servicemaster Mgt. Servs. Corp., 83 NY2d 579, 589).
