What is one of the best information sources about an occupancy?

When it comes to understanding the specifics of an occupancy, a record of previous inspections and incident reports serves as one of the most reliable information sources. These records provide essential historical data about the building, including any fire hazards identified in the past, the types of incidents that have occurred, and how effective previous responses were. This documented information allows for better preparedness and risk assessment during emergencies.

While other sources such as the building manager or occupants can provide valuable insights, they may not have comprehensive knowledge of the building's history or previous incidents. Fellow firefighters can offer practical experience but might lack detailed data concerning that specific occupancy. In contrast, the documented records serve as an objective and thorough source, making them invaluable for enhancing safety measures and planning effective response strategies.
