A safety device comprising a floor drain grate includes at least two separate regions, and preferably three, with openings through which water can flow into a pool drain. The regions are preferably spaced to either side of the pool drain, by a distance which effectively prevents a swimmer from blocking all the openings at once and becoming stuck to the grate by suction. The floor drain grate may be provided as a retrofit to replace an existing drain grate of a pool.

[ What is claimed is:] [1.] A safety device for a drain on a floor of a pool or spa, comprising:an elongate flow passage structure adapted to overlie said floor drain and extend outwardly from said drain on at least one side of said drain, said flow passage structure having at least two openings spaced from each other by a predetermined distance and comprising an elongate channel portion configured to conduct fluid in a direction toward said drain, said elongate channel portion comprising walls which extend along said direction so as to form an elongate substantially enclosed flow path, said elongate flow passage structure being configured to provide fluid communication between each of said openings and said drain to allow water from said pool or spa to be drawn through each of said openings into said drain by suction, said predetermined distance being at least about a foot and a half to effectively inhibit a human body from blocking all of said openings at the same time, whereby one of said openings has substantially unrestricted fluid communication with said drain.
