If a fire occurs in the lavatory, how many extinguishers are essential to have available?

Having two fire extinguishers readily available in the lavatory is essential for effective emergency response. The presence of two extinguishers allows for a primary and a backup device, ensuring that if one needs to be used or becomes inoperable, there is still another available for use. This redundancy is crucial in a confined space like a lavatory, where fires can spread quickly and effectively combating them might require immediate access to extinguishing equipment from different angles or approaches. Additionally, two extinguishers enhance safety for both passengers and crew by enabling trained staff to manage the situation more effectively, thereby minimizing potential injuries or further hazards.
