Which bulb color corresponds to a temperature rating of 286?

• A. Blue
• B. Mauve
• C. Black
• D. Uncolored

Answer: (A)

In the context of sprinkler systems, the color of the bulb in a glass sprinkler head indicates the temperature rating at which the sprinkler will activate. The color coding corresponds to specific temperature ratings, ensuring that sprinkler systems function optimally in the event of a fire. A bulb color of blue signifies a temperature rating of 286°F (or approximately 139°C). This coding is part of a standardized system used to differentiate the activation temperatures of various sprinkler heads, allowing for the appropriate selection based on the environmental conditions in which they are installed. The other options do not correspond to the temperature rating of 286°F. The mauve bulb is typically associated with a lower temperature rating (around 200°F), the black bulb corresponds to a much higher temperature rating (like 500°F), and uncolored bulbs are often linked to temperature ratings around 165°F. Therefore, the blue bulb is accurately indicative of the specific temperature rating needed for effective fire suppression at 286°F.
