Escalator Safety for Owners


Injuries occur about 15 times more frequently on escalators than elevators. About 10,000 escalator-related injuries per year result in emergency-room treatment in the U.S. Most of these accidents can be avoided if safety issues are addressed. People who use escalators generally do not recognize the risks and possible dangers associated with these devices, and some escalator service technicians do not consistently adhere to safety protocol. The fact that serious or fatal injuries continue to occur globally underscores the need for diligent implementation of safety measures at all levels.

Antimicrobial properties of copper and copper alloys


There have been many studies on antibacterial properties of copper and copper alloys. Most have been in hospital or care home settings and concentrating on bacteria, rather than viruses. Although marketing literature of copper alloys as antimicrobials stresses their use in hospital settings, no hospital relies solely on these surfaces to kill microbes. Continuous sterilisation and disinfection with heat, chemicals and steam is practised where contamination could be an issue. Anti-microbial surfaces are used as supplementary and interim cleaners and to prevent biofilm build-up between disinfections. Time to kill microbes is on the scale of hours, whereas equipment, railings and buttons can be touched every few seconds to minutes.
