Which statement is true regarding fire sprinklers?

In the context of fire sprinkler systems, the markings on the sprinkler heads are crucial for identifying their temperature classifications. Sprinklers are designed to activate at specific temperatures to control or suppress fires effectively, and these classifications are indicated by color-coded markings.

The statement about green markings indicating a very-extra-high temperature classification is correct. Such color coding aligns with the industry standards established by organizations like the National Fire Protection Association (NFPA). The classifications are important because they ensure that the sprinklers will activate at the appropriate temperature depending on the area where they are installed, whether it be industrial settings, commercial spaces, or other environments with varying risks of fire.

The various colors represent different activation temperatures, with red indicating a lower temperature classification. Understanding these markings helps safety professionals and installation teams select the proper sprinkler heads for their specific applications, ultimately contributing to effective fire protection.
