By what year did steam engines disappear from use in fire fighting?

The transition away from steam engines in firefighting culminated in the mid-1920s, making the year 1925 a significant marker in this evolution. By this time, advancements in technology led to the wide adoption of motor-driven fire apparatus, which offered firefighters greater efficiency, speed, and flexibility compared to the steam-powered units.

Steam engines, while pivotal in the development of firefighting methods during the 19th and early 20th centuries, were gradually phased out as newer, more effective technologies emerged. This shift not only improved response times during emergencies but also enhanced the overall effectiveness of firefighting operations.

The timeline indicates that while steam engines were still in operation in the early 1920s, they had largely disappeared from active use by 1925, as fire departments across the country began fully embracing motorized vehicles. Other choices suggest a timeline that extends beyond this crucial period of change, which does not align with the historical progression of firefighting technology.
