Defendants Sunbeam's and Pergament's affidavits in support of their motions for summary judgment were insufficient to prove, as a matter of law, that this manufacturer and retailer had each discharged its independent duty to exercise reasonable care to inform a product user of the dangers attendant to this propane gas grill ( see, Lancaster Silo Block Co. v. Northern Propane Gas Co., 75 A.D.2d 55, 64-65).
Although there is no duty on the part of a manufacturer or retailer to warn a customer about obvious hazards, here, knowledge of the propensity of propane, a gas heavier than air, to accumulate from ground level upward in a partially screened area cannot be assumed. This hazard was not manifest, and the reasonableness of the warnings, if any, provided by these defendants, is an issue of fact to be submitted to a jury.
We have considered and rejected the parties' additional claims.
