Wash your hands properly for 20 seconds
Health & First AidThe CDC 5-step routine - wet, lather, scrub 20 seconds, rinse, dry - removes germs and helps prevent illness.
- Wet hands
- Lather with soap
- Scrub 20 seconds
- Rinse and dry
Steps
- Wet your hands with clean, running water, turn off the tap, and apply soap.
- Lather the backs of your hands, between your fingers, and under your nails.
- Scrub your hands for at least 20 seconds (hum 'Happy Birthday' twice).
- Rinse well under clean, running water, then dry with a clean towel or air dryer.
Why it works
Clean hands stop germs from spreading to your eyes, nose, mouth, food, and other people, lowering the chance of getting sick or spreading illness.
Good to know: General information, not medical advice. Handwashing reduces but does not eliminate risk; use soap and water when hands are visibly dirty, and see a clinician for any illness.

Health & First AidRun cool water over a minor burn for about 20 minutes and remove tight items - never use ice, butter, or creams.
- Move from heat
- Cool ~20 min
- Remove tight items
- No ice or butter
Steps
- Stop the burning - move away from the heat source.
- Cool the burn with cool or lukewarm running water for about 20 minutes, as soon as possible.
- Remove any clothing or jewellery near the burn, but do not move anything stuck to the skin.
- Never use ice, iced water, creams, or greasy substances like butter; once cooled, lay cling film over it (do not wrap).
Why it works
Cool running water lowers skin temperature and limits tissue damage and pain, while ice, butter, and creams can worsen the injury or trap heat.
Good to know: General information, not medical advice. Call emergency services for large, deep, or facial burns, chemical or electrical burns, or burns on a baby or older person. Do not pop blisters; see a clinician if unsure.
