Infection Control
Of concern is the fact that door handles are instrumental in the spread of many infections. However, some materials, e.g. brass, copper and silver, are slowly poisonous to many germs. The exact mechanism is not known, but is commonly thought to be via the oligodynamic effect, perhaps by some other electrostatic effect. Brass and copper, for example, disinfect themselves of many germs within eight hours. Other materials such as glass, porcelain, stainless steel and aluminium do not have this effect. Self-disinfecting door handles are particularly important in hospitals, but useful in any building.

Famous quotes containing the words infection and/or control:
“What, then, was war? No mere discord of flags
But an infection of the common sky
That sagged ominously upon the earth”
—Robert Graves (1895–1985)
“There has been something crude and heartless and unfeeling in our haste to succeed and be great. Our thought has been “Let every man look out for himself, let every generation look out for itself,” while we reared giant machinery which made it impossible that any but those who stood at the levers of control should have any chance to look out for themselves.”
—Woodrow Wilson (1856–1924)
