ABSTRACT OF THE INVENTION A low impedance safety guard for an air circulating fan with rotating fan blades which prevents a human hand, finger or foot from getting into the path of the rotating blades while yet achieving the unrestrictive air stream benefits of a relatively open guard which is generally considered unsafe. The guard comprises rear and front parallel and opposing substantially open, air stream unobstructive fan blade guard faces which will permit the hand, finger or foot to pass partially therethrough. A substantially closed circumferential wall is provided which connects the rear and front faces to enclose the fan blades approximately equal distant from the respective faces to prohibit the hand, figure or foot from reaching the blade path after passing partially through either face should a person unfortunately attempt to do so.
