Hand Sanitizers: When and How to Use Them for Covid-19 Protection
Updated: Feb 28
Health authorities recommend the use of hand sanitizers as an effective way to remove and prevent the spread of germs, and getting infected. To ensure the safety of your organization, make hand sanitizers available and encourage their proper and regular use.
The advice below on the most effective use of hand sanitizers is based on data from a number of studies, and guidelines from the UK National Health Service (NHS) and the US Centers for Disease Control and Prevention (CDC).
Which type of hand sanitizer is most effective?
Studies have found that sanitizers with an alcohol concentration between 60–95% are more effective at killing germs than those with a lower alcohol concentration or non-alcohol-based products.
Organizations are advised to make regular or automatic hand sanitizer dispensers available in prominent places at their venues.
How to apply the hand sanitizer
Hand sanitizers (gel or liquid) are solutions to be placed onto dry hands. When using hand sanitizer, apply the product to the palm of one hand and rub the product all over your hands until they are dry. Read the label to apply the correct amount.
How and when not to use hand sanitizers
· Ethyl alcohol (ethanol)-based hand sanitizers are safe when used properly, but they can cause alcohol poisoning if swallowed. Hand sanitizers should be stored out of the reach of young children.
· Many studies show that hand sanitizers are effective when hands are not heavily soiled or greasy. Hand-washing with soap and water is recommended in such circumstances.
· Hand sanitizers might not remove harmful chemicals, like pesticides and heavy metals, from hands.
· Don’t use hand sanitizers immediately after washing your hands with soap and water.
Maximum comfort encourages regular use
Quality hand sanitizers ensure maximum comfort. They cover the skin easily and are absorbed quickly with no sticky feeling after application. The formula can contain ingredients that soften and refresh the skin. It is essential that the hand disinfectant doesn’t cause sensitization after multiple applications.
