Abstract
A safety railing system and a method provide a walkway on a tanker trailer so that a user may access the top of the tanker trailer. A ladder provides access to the walkway connected to a frame on the tanker trailer. A railing adjacent to the walkway provides a handrail for the user. A lever pivots relative to the frame to move the railing from a collapsed position to an upright position for use. The railing locks in the upright position for use and also locks in the collapsed position for stowage during transport of the tanker trailer.
