Why colour coding
Colour coding stops equipment used in high-risk areas, like toilets, ending up in kitchens or care areas — one of the most common ways cleaning spreads germs.
A commonly used system
- Red: toilets and urinals.
- Yellow: bathrooms, showers and basins (excluding toilets).
- Blue: general areas such as offices and corridors.
- Green: kitchens and food areas.
Systems vary between sites and organisations, and healthcare settings may use their own. Always follow the chart on your site.
Making it work
- Store each colour separately.
- Launder or replace cloths and mop heads as the procedure requires.
- If you're unsure which colour to use, ask — don't guess.
