Abstract
A helicopter landing platform comprises a fine mesh grid supported on a coarse mesh grid above a horizontal surface such as an ordinary helicopter landing pad. The grid structure is supported in superposed spaced relationship by a supporting framework; and conduits and nozzles for foam fire extinguishing agent are disposed in the space between the grid work and the horizontal surface. Burning oil thus falls through the mesh and is extinguished by the foam, the mesh preventing the foam from blowing away and also providing an anti-skid surface for the helicopter. The platform can be subdivided into a number of units; and the periphery of the platform is surrounded by a rim.
