Antimicrobial copper-alloy touch surfaces Antimicrobial copper-alloy touch surfaces Antimicrobial copper-alloy touch surfaces can prevent frequently touched surfaces from serving as reservoirs for the spread of pathogenic microbes. This is especially true in healthcare facilities, where harmful viruses, bacteria, and fungi colonize and persist on doorknobs, push plates, railings, tray tables, tap (faucet) handles, IV poles, HVAC systems, and other equipment. These microbes can often survive on surfaces for surprisingly long periods of time (sometimes more than 30 days). The surfaces of copper and its alloys, such as brass and bronze, are antimicrobial. They have an inherent ability to kill a wide range of harmful
Sundown Tin and Copper Mine the slag was cast into sand moulds, typical of reverberatory furnace practice. East of the furnace are a number of sleepers, lengths of wire cable, and the base of the structure which could be the flying fox used to bring tin and copper ore to the mill site. However, this area of the site has been extensively disturbed by more recent bulldozing and earth moving activities. The two dams are located below the Old Works site, and are earthen dams, riveted with timber on the downstream side, and both are broken. A large amount of tailings sand lines the creek
