What colour should waterproof dressings be, and why?

• A. Red, to indicate injury
• B. Clear, to be inconspicuous
• C. Blue, to aid detection if they fall off
• D. Green, to signal safety

Answer: (C)

The main idea is choosing a dressing color that is easy to notice if it comes loose, so any leakage or loss is spotted quickly and can be replaced to prevent contamination. Blue is preferred because it stands out against most foods, backgrounds, and surfaces, and it isn’t a common color in food itself. This makes a fallen or damaged dressing easy to detect during inspections. Clear dressings can blend in with skin or work surfaces, making them hard to see, and red could be mistaken for blood, causing unnecessary concern. So blue helps ensure visibility and timely replacement, keeping food safety under control.
