What is the number of water fire extinguishers installed on the ERJ 175 aircraft?

The ERJ 175 aircraft is equipped with one water fire extinguisher. This design choice aligns with safety protocols and regulatory requirements, ensuring adequate fire suppression capabilities while also considering weight and space constraints in the aircraft. Having a single water fire extinguisher simplifies accessibility for cabin crew during emergencies while still being effective for specific types of fires, particularly those involving materials like paper and cloth, which may occur in passenger cabin environments. Keeping the number limited helps streamline emergency procedures and reduce the overall complexity of the safety equipment onboard.
