A sprinkler with blue liquid in the bulb would discharge at what temperature?

The correct answer, which indicates that a sprinkler with blue liquid in the bulb would discharge at a temperature of 286°F, is associated with the type of liquid used in the thermal sensing element of the sprinkler. Sprinkler systems use different colored liquids in their bulbs to indicate different activation temperatures. The blue liquid specifically corresponds to a high-temperature rating, and in this case, it is designed to activate at 286°F.

Understanding the significance of these colors and their corresponding temperatures is essential for a sprinkler fitter, as it allows for the correct selection and installation of sprinklers based on the heat conditions expected in the specific environment. This information is crucial in ensuring that the sprinkler system will function effectively, providing adequate fire protection when needed.
