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 above the dams, leaching the metallic salts and having a strongly sulphurous smell. The Copper Mines are located about east of the furnace site, and consist an adit near the creek, and a series of 3 shafts along the line of the reef running roughly s-w to n-e over the crest of the ridge, and mullock associated with the shafts. The main shaft is a three-compartment shaft. There is a collapsed ore bin and shute, and some concrete machinery pads, but no other substantial above- ground remains. Sundown Tin and Copper Mine was listed on the Queensland Heritage Register on
