What is the minimum number of operative fire extinguishers which must be carried on a bus (single deck)?

In the context of German traffic regulations, buses are required to carry fire extinguishers to ensure the safety of passengers in case of a fire emergency. The specific regulations dictate that at least one operational fire extinguisher must be present on a bus. However, if the bus is equipped to hold 12 or more passenger seats, it is mandated to have two fire extinguishers. This requirement ensures that in the event of a fire, there are sufficient means to tackle the situation effectively and protect the safety of all passengers. Therefore, understanding both the minimum requirement for smaller buses and the increased requirements for larger ones is crucial for compliance with safety regulations.
