During hot works near a sprinkler head, what should you do to prevent the fire alarm from triggering?

• A. Put a non-combustible barrier to protect the sprinkler head
• B. Install an electrical barrier
• C. Seal the sprinkler head with tape
• D. Increase heat in area

Answer: (A)

When doing hot work near a sprinkler head, radiant heat and sparks can cause the head to activate and trigger the alarm or sprinkler discharge. A non‑combustible barrier placed to shield the sprinkler head keeps the heat and sparks away, allowing the work to continue safely without triggering the system. This barrier should be specifically designed for sprinkler protection, non‑combustible, and removed after the work is finished with the area checked for safety. Other approaches, like taping the head or increasing heat, would either impede proper sprinkler function or make false activation more likely.
