Which system must remain operational during hot work operations?

During hot work operations, the sprinkler system protection must remain operational to ensure immediate and effective response to any potential fires that may be ignited due to sparks or heat from these activities. Sprinkler systems are designed to control and extinguish fires, thereby providing a critical level of safety in environments where combustible materials may be present.

Keeping the sprinkler system operational ensures that if a fire occurs, it can be suppressed quickly, minimizing damage and enhancing the safety of workers and facilities. This is particularly important in settings where hot work is conducted, as the risk of ignition is significantly heightened.

While other systems such as the electrical system, fire alarm system, and HVAC system are also important for overall safety and operational effectiveness, the sprinkler system specifically addresses the fire risks associated with hot work operations directly. Therefore, maintaining the functionality of the sprinkler system during these activities is paramount to preventing fire outbreaks and ensuring a safe working environment.
