Which sprinkler type is most commonly used since 1953 for fire control?

The most commonly used type of sprinkler for fire control since 1953 is the spray sprinkler. This type has been widely adopted in fire protection systems due to its effective design and performance. Spray sprinklers are designed to distribute water over a specific area in a uniform manner, providing rapid fire suppression capabilities. Their quick response time and ability to cover large areas make them particularly suitable for a variety of environments, including commercial and residential applications.

The design of the spray sprinkler allows for a higher volume of water to be dispersed in a shorter amount of time, which is critical during the early stages of a fire when immediate control is essential. Additionally, advancements in materials and technology have improved their reliability and efficiency, contributing to their popularity over the decades.

In contrast, other sprinkler types may have been effective in earlier fire protection systems but do not match the widespread application and performance characteristics of the spray sprinkler.
