Sprinklers must have a temperature rating of at least what degree Fahrenheit?

The correct answer is: 135

Sprinklers are essential components of fire protection systems, and their temperature rating is critical for ensuring that they activate at the appropriate time during a fire incident. The temperature rating indicates the point at which the sprinkler will operate to release water and help suppress flames. A temperature rating of at least 135 degrees Fahrenheit is commonly required for standard glass bulb sprinklers, which are designed to respond to heat. When temperatures reach this threshold, the glass bulb containing a liquid inside expands, ultimately breaking and allowing water to flow out of the sprinkler head. This operational temperature is significant because it ensures that sprinklers will activate efficiently in the event of a fire, providing an essential level of safety in buildings. The other temperature options listed, while relevant to different situations or types of sprinklers, do not reflect the standard minimum required for activation in typical settings. Thus, the choice of 135 degrees Fahrenheit effectively aligns with industry standards and safety regulations concerning fire suppression systems.
