Any type of rail attached to a bed should be assessed for entrapment risks. Full-length rails should be tested in the same manner as any other type of rail. Note that some full-length rails can present an entrapment risk when the bed is articulated (e.g., head elevated, knees raised), thus testing full-length rails in articulated bed positions is particularly important. The video provides a general guide to bed assessment, and the dimensional test method provided detailed instruction on bed assessment.
