While performing hot works near a sprinkler head, what can be done to prevent the fire alarm from activating?

When performing hot work near a sprinkler head, the primary consideration is to prevent accidental activation of the fire alarm and sprinkler systems due to heat or sparks. Using a non-combustible barrier to protect the sprinkler head is effective because it can shield the sprinkler from heat, sparks, and other contaminants that may trigger the system by simulating a fire condition.

The non-combustible barrier acts as a physical separator between the hot work and the sprinkler, maintaining both the integrity of the work being done and ensuring that the sprinkler head does not mistakenly activate in reaction to perceived fire hazards. This approach is consistent with safety protocols that prioritize both fire prevention and the functionality of fire suppression systems during maintenance or construction activities.

Using a fire extinguisher is not directly relevant to preventing the fire alarm from activating, as it does not address the issue of potential ignition or heat impacting the sprinkler head. Covering the sprinkler head with plastic can be counterproductive; it may trap heat and actually increase the chance of activation because the plastic may melt and create a condition that resembles a fire. Switching off the fire alarm system is not advisable; it can place everyone at risk by removing a critical safety layer and is typically against fire code regulations.
