A safety barrier for a sump pit is disclosed. The safety barrier cooperates corrugations or discontinuities in the sump pit to support the safety barrier within the sump pit. The safety barrier includes a planar platform and at least two extendible legs that are attached to the planar platform. The extendable legs are used to contact or engage corrugations or discontinuities in the sump pit. The extension of extendable legs from the planar platform traps the device within the recessed surface of one of the corrugations or discontinuities of the sump pit.

1. A safety barrier for a sump pit, the sump pit including corrugations, at least one of the corrugations including a continuous recessed surface, the safety barrier comprising: a planar platform having a perimeter with a concave recessed section that extends into the plane of the planar platform in a co-planar manner relative to the plane of the planar platform;at least one fixed leg that projects to a fixed distance from the planar platform, the at least one fixed leg being positioned next to the recessed section, and two coplanar extendible legs that are attached to the planar platform, each of the at least one fixed leg and two coplanar extendible legs being at an angle of less than 180 degrees to one another, the two coplanar extendable legs extending away from the planar platform along a direction that is generally parallel to the platform and away from the recessed section, the two coplanar extendible legs extending next to and along the recessed section;said recessed section of the planar platform being generally V-shaped and is bounded by edges that extend next to each of at least one fixed leg, so that the extendable legs protrude away from the planar platform in a manner that is generally parallel to the edges of the recessed section;and the two coplanar extendible legs being adapted for extending from the planar platform to the recessed surface of the sump pit, so that positioning the at least one fixed leg within one the recessed surface of one of the corrugations allows the user to extend the two coplanar extendible legs away from the planar platform until the two coplanar extendible legs contact the continuous recessed surface to support the planar platform against the recessed in the sump pit and vary the position of the recessed section of the perimeter. 2.
