In the context of fire protection and sprinkler systems, the color markings on the sprinklers are critical for determining their temperature classifications. Sprinklers with green markings are specifically designed to operate in environments where the ambient ceiling temperature can reach a maximum of 375 degrees Fahrenheit. This allows for proper functionality in settings that may experience higher temperatures, ensuring that the sprinkler will activate when needed without being falsely triggered by normal ambient conditions.

Choosing the correct temperature classification is essential in the design and installation of fire protection systems, as it directly influences the effectiveness of the sprinklers in protecting a space. The classification helps ensure that sprinklers operate at the proper time, providing an optimal response to fire conditions while minimizing potential damage from premature activation.
