A method for manufacturing a wound dressing having a substrate, and a wound dressing manufactured by such a method are described. The method has a step of providing a sacrificial layer of material to be perforated by means of a hot pin perforator, in order to remove any molten residues on the heated pins of the hot pin perforator, before the same pins are used to make holes in the substrate. The presented method is cost effective, robust and reduces the risk of contaminating substances being embedded in the substrate during the hole making process.

An installing hole forming mechanism includes at least one guiding sleeve and an inserting set. The at least one guiding sleeve includes a bore. The inserting set is detachably coupled to the at least one guiding sleeve and includes at least one spike configured to couple to the bore of the at least one guiding sleeve. The at least one spike includes a tip. When the at least one spike passes through the bore of the at least one guiding sleeve, the tip exposes from the guiding sleeve, and the at least one spike and the at least one guiding sleeve are forced to puncture a shoe such that at least one installing hole is formed on the shoe.

A device and process for cleaning and decommissioning used chemical jugs or containers of any size, including an upper positioned clean water manifold which feeds a pressurized inlet fluid to a vertically downwardly arrayed elongated and spike shaped component having a sharpened lower end, the spike shape component being downwardly actuated for successively piercing at least one wall of the container. The hollow spike shaped component also includes a plurality of laterally and/or angularly positioned pressurized fluid outlets for issuing fluid evenly across the inside surface area of the jug for subsequent drainage through a pierced bottom of the jug.
