Introduction
Hand hygiene is one of the simplest yet most effective ways to prevent illness and protect both personal and public health. Whether you are preparing food, working in healthcare, or simply going about your daily routine, knowing the correct hand hygiene steps is vital. This guide explains when and how to wash your hands, why it matters, and how to maintain clean hands in different settings.
Why Hand Hygiene is Essential for Health and Safety
Germs are invisible but powerful. They spread easily through direct contact and contaminated surfaces, and our hands are the most common carriers.
- According to the World Health Organization (WHO), proper hand hygiene can reduce the spread of diarrhoeal diseases by up to 40% and respiratory illnesses like colds and influenza by nearly 25%.
- In workplaces, especially those involving shared equipment or food handling, unwashed hands can lead to widespread illness. Maintaining proper hygiene helps protect yourself, colleagues, and the wider community.
The Impact of Poor Hand Hygiene
Failing to wash your hands correctly can result in the transmission of infections such as:
- Influenza
- COVID-19
- Norovirus
- Gastrointestinal illnesses
Case studies show that workplace outbreaks, particularly in aged care and food industries, have been drastically reduced through consistent hand hygiene protocols. Poor hand hygiene in food handling environments can result in foodborne illnesses such as salmonella, E. coli, and norovirus outbreaks.
How Hand Hygiene Saves Lives
In hospitals, poor hand hygiene is a major contributor to healthcare-associated infections (HAIs), which can be fatal. Correct handwashing practices by staff and visitors can reduce HAIs by up to 50%.
It also protects vulnerable groups such as children, the elderly, and those with weakened immune systems from avoidable illnesses.
The 5 Moments for Hand Hygiene
The Australian Commission on Safety and Quality in Health Care supports the National Hand Hygiene Initiative (NHHI), which outlines five critical moments for hand hygiene.
Before Touching a Patient or Food
Clean your hands before treating a patient or preparing food. This prevents germs from being transferred.
After Touching Contaminated Surfaces or Materials
Doorknobs, lift buttons, and shared keyboards are common carriers of germs. Wash or sanitise your hands after contact.
After Using the Toilet or Touching Personal Items
Toilets and personal items such as phones and wallets can carry bacteria. Wash your hands immediately afterwards.
After Coughing or Sneezing
Droplets carry germs. Even if you use a tissue or sneeze into your elbow, always clean your hands.
When Hands Are Visibly Dirty
If your hands are greasy, soiled, or covered in food, wash with soap and water. Sanitiser alone will not work.
How to Properly Wash Your Hands
Follow these steps for effective handwashing:
- Wet Hands and Apply Soap
- Use clean, running water.
- Apply enough soap to cover all surfaces.
- Use clean, running water.
- Scrub All Areas of Your Hands
- Rub palms together.
- Scrub backs of hands, between fingers, under nails, thumbs, and wrists.
- Continue for at least 20 seconds.
- Rub palms together.
- Rinse and Dry Thoroughl
- Rinse well under running water.
- Dry with a clean towel or air dryer.
- Remember: wet hands spread germs more easily.
- Rinse well under running water.
Hand Sanitiser vs Handwashing: When to Use Each
Hand sanitiser is useful but does not replace soap and water in all situations.
| Use Hand Sanitiser | Wash with Soap and Water |
| When soap and water aren’t available | After handling raw meat or food waste |
| In low-risk settings | When hands are greasy, sticky, or visibly dirty |
| If hands are not visibly dirty | After toileting, gardening, or pet handling |
Choose an alcohol-based sanitiser with at least 60% alcohol for effectiveness.
