Abstract

See full text

Systems and methods for making and using manhole safety gratings are described. Each safety grating includes a plate that has a first surface, a second surface, and a perimeter edge that extends between the two surfaces. The plate also defines a plurality of vents that extend between the first surface and the second surface. The plate can have any suitable shape or size that fits within the desired manhole. The plate can comprise any suitable material and be any suitable weight that provides the desired protection to the manhole. The safety gratings can therefore provide temporary safety for the manhole when they are used in place of permanent safety gratings. Other embodiments are described.
