A supply management system for first aid supplies employs an organizing board. The organizing board has a multiplicity of forward axially projecting pegs which are configured in a generally rectangular grid. A plurality of first aid items are each contained in a box-like container having a rear mounting panel. The mounting panel has a matrix of structures defining apertures corresponding in spacing to selected portions of the grid of pegs. Each first aid container is mountable to the board in a stable position whereby selected pegs are received in apertures of the mounting panel and the panel is disposed forwardly from the board. The structures are deformable and have a generally circular central portion with a plurality of radial perforations which form tabs. The organizing board is preferably placed against the rear of a first aid cabinet. The organizing board and the matrix of apertures ensure compatibility of first aid replacement products.
