For lavatory fire extinguishers, how many should be placed over the waste bins?

The correct answer is two lavatory fire extinguishers placed over the waste bins. This is in alignment with safety protocols designed to minimize fire hazards, particularly in high-risk areas like lavatories where flammable waste is present.

Having two extinguishers provides an added level of safety and ensures that in the event of a fire, there is a higher chance of successfully extinguishing it quickly. This redundancy allows for effective coverage from multiple angles, which is particularly critical in enclosed spaces where fire can spread rapidly.

The placement of these extinguishers is strategic, focusing on the areas where the risk of fire is greatest, thereby enhancing the overall safety measures on the aircraft. By ensuring that lavatory fire extinguishers are easily accessible and adequately positioned, flight attendants can respond promptly should a fire occur, ultimately safeguarding the passengers and crew on board.
