Question 75

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 to activate at temperatures ranging from 175 to 225 degrees Fahrenheit, making this the correct choice.

A) 135 to 170 degrees F

This option is incorrect because it represents a lower temperature range, which does not correspond to the blue color code for sprinklers. Sprinklers with this temperature rating typically have a different color code, such as orange or yellow.

B) 175 to 225 degrees F

This option is correct as it accurately reflects the temperature rating associated with the blue color code for sprinklers. This range indicates the activation point for these specific sprinklers in fire protection systems.

C) 250 to 300 degrees F

This option is incorrect because it indicates a higher temperature range, which is not associated with the blue color code. Sprinklers rated for this temperature would typically be color-coded differently, such as red or white.

D) 325 to 375 degrees F

This option is also incorrect; it represents an even higher temperature range that does not correspond to the blue color code. Similar to option C, sprinklers in this range would have a different identification color.

Conclusion

The correct answer, B, is definitively right as it matches the established temperature rating for blue color-coded sprinklers. All other options provide temperature ranges that do not align with the blue code, thereby confirming their incorrectness. Understanding the color code system is crucial for ensuring proper fire safety measures are implemented.
