Healthcare Germ Hot Spots
Creating a more hygienic health care facility doesn’t stop at the restroom. Targeting “hot spots” with hand and surface hygiene, is a key step toward reducing the spread of germs.
Placing hand sanitizer and signage in offices and common areas is a step in the right direction. But studies show it simply isn’t enough to make a real impact. Objects that are touched by lots of people throughout the day − such as doorknobs, elevator buttons and handrails − should be cleaned and disinfected daily in order to help break the chain of germ transmission.
No matter which surfaces they may touch throughout their day, give your staff, patients and visitors peace of mind by providing proven cleaning and disinfecting solutions to help break the chain of germ transmission.
Cleaning these hot spot areas will help reduce germs in healthcare facilities
- Elevator buttons
Cleaning removes germs, dirt, and impurities from surface objects. Cleaning works by using soap (or detergent) and water to physically remove germs from surfaces. This process does not necessarily kill germs, but by removing them, it lowers their numbers and the risk of spreading infection.
Disinfecting kills germs on surfaces or objects. Disinfecting works by using chemicals to kill germs on surfaces or objects.* This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection.
Hand Sanitizing kills germs on the body. The FDA regulates all topical antiseptic products such as hand sanitizers. These products are intended to be used when soap and water are not available and are not rinsed off with water.
Steps to make it easy to drive cleaning and hygiene habits
Clean the surface of commonly touched objects — use detergent or soap and water prior to disinfection.
Disinfect the surface — use EPA-registered household disinfectants. Follow manufacturer’s instructions for application and dwell time.
