What must be documented in the report after a fire alarm is restored?

The correct answer focuses on the importance of documenting the responsible party's (RP's) name in the report after a fire alarm is restored. This documentation is crucial for accountability and communication. Knowing who is in charge allows for follow-up questions or actions if necessary. Additionally, it helps establish a clear chain of responsibility for any issues that may arise, such as false alarms or maintenance needs.

While details like the name of the fire marshal, time of alarm activation, and type of alarm system are all important elements in documenting a fire incident, they serve more specific roles. For example, the time of alarm activation might be necessary for incident timelines or investigating the fire's origin, while the type of alarm system helps in understanding the technology used at the location. However, the identity of the responsible party is essential for ongoing safety and operational procedures and is what makes option B particularly significant in the context of fire incident reporting.
