During a 20-minute toilet check, what should be ensured about waste bins?

Ensuring that the waste bin flap remains closed is crucial for maintaining hygiene and safety onboard an aircraft. A closed flap prevents unpleasant odors from escaping, minimizes the risk of spillage, and helps contain any potential contaminants that may be present in the waste. This practice is also significant for compliance with safety regulations and proper waste management protocols.

Keeping the flap closed contributes to a more sanitary environment for both crew and passengers, as it helps to limit the spread of germs and bacteria. Furthermore, a closed waste bin flap is less likely to attract pests or cause distractions during the flight. Overall, this practice aligns with best practices in crew resource management and safety, ensuring a level of cleanliness and professionalism on the aircraft.
