What is foil on doorknobs for safety?

Foil on doorknobs is said to be a safety measure to prevent the spread of germs and viruses from one person to another. It works by creating a temporary barrier on the surface of the doorknob, which can be easily disposed of after each use.

Foil on doorknobs also provides protection against electrical shocks, as it eliminates contact with any exposed wiring that may be present in the knob. This is especially important in older buildings where electrical systems may not be up to code.

Additionally, foil on doorknobs can also act as a visual reminder to wash hands regularly and practice good hygiene, as it highlights the need for increased attention to hygiene in high-traffic areas.

Overall, foil on doorknobs provides a simple, low-cost way to promote safety and hygiene in public spaces.
