When sprinklers are installed near a heat source, what must be considered?

• A. They can use any rating.
• B. They must be replaced with dry sprinklers.
• C. They need specific ratings.
• D. They should be disabled near heat sources.

Answer: (C)

Sprinklers have temperature ratings that determine when they will release water. If a head is placed near a heat source, the surrounding ambient temperature can be higher than in other locations, which can affect how the head responds. To ensure proper operation, you must choose a sprinkler with a temperature rating appropriate for the expected ambient heat in that location. A higher rating may be needed near heat sources so the head won’t activate solely from ambient warmth, while still providing reliable operation when a real fire occurs. This is why the correct approach is to account for specific ratings based on the environment. Replacing with dry sprinklers or disabling heads near heat sources isn’t required or appropriate unless the design calls for it, and using an arbitrary rating isn’t correct.
