75. What is the temperature rating for a sprinkler with a blue color code
Answer: B
The temperature rating for a sprinkler with a blue color code is 175 to 225 degrees F.
Sprinklers with a blue color code are rated for temperatures between 175 to 225 degrees Fahrenheit, making them suitable for specific fire protection applications.
A) 135 to 170 degrees F
This option is incorrect as it corresponds to a lower temperature range typically associated with sprinklers that have a different color code, not blue. The blue color code specifically indicates a higher temperature rating.
B) 175 to 225 degrees F
This option is correct. The blue color code signifies that the sprinkler operates effectively within the 175 to 225 degrees Fahrenheit range, which is essential for certain environments that require higher temperature thresholds.
C) 250 to 300 degrees F
This option is incorrect because it represents an even higher temperature rating than what is designated by the blue color code. Sprinklers rated for this range typically have a different color indicator.
D) 325 to 375 degrees F
This option is also incorrect, as it pertains to a significantly elevated temperature range beyond the blue color code's designation. Such temperatures are usually marked by yet another specific color code.
Conclusion
The correct answer, 175 to 225 degrees F, is definitively right as it accurately reflects the temperature rating for blue-coded sprinklers. All other options fail to align with the established color coding system, which is critical for ensuring proper fire safety measures.
