Silent auction is a variant of the English auction in which bids are written on a sheet of paper. At the predetermined end of the auction, the highest listed bidder wins the item. This auction is often used in charity events, with many items auctioned simultaneously and "closed" at a common finish time. The auction is "silent" in that there is no auctioneer selling individual items, the bidders writing their bids on a bidding sheet often left on a table near the item. At charity auctions, bid sheets usually have a fixed starting amount, predetermined bid increments, and a "guaranteed bid" amount which works the same as a "buy now" amount. Other variations of this type of auction may include sealed bids. The highest bidder pays the price he or she submitted.
Bidder acknowledges that an auction site is a potentially dangerous place. Flammable, noxious, corrosive and pressurized substances are present, heavy equipment is being operated and electric circuits may be live. Every person at the auction site, at any time, shall be there at his own risk without notice of the condition of the premises and the activities thereon and bidder shall so advise his agents and employees. No person shall have any claim against Auctioneer, its officers, directors, agents, employees, principals, or attorneys for any injuries sustained, nor for damages to or loss of property, which may occur from any cause whatsoever.
