What must be documented during fire drills conducted for all building occupants?

In the context of fire drills conducted for all building occupants, the most critical aspect that must be documented is all training received. This encompasses not only the specifics of the fire drills but also any additional training provided to occupants about fire safety procedures, the operation of fire protection systems, and other relevant safety protocols. Thorough documentation ensures compliance with safety regulations and provides a record that can be reviewed for efficacy in improving safety procedures and response times during actual emergencies.

While attendance and individual performances, types of drills, and emergency exit routes are important elements of fire safety, they serve more specific purposes and may not encompass the full scope of training needed for effective emergency preparedness. Documenting all training received allows for a comprehensive overview of how well occupants understand their responsibilities during a fire event, thereby enhancing overall safety within the building.
