Which factor is commonly addressed in basic fire prevention?

In the context of basic fire prevention, addressing blocked fire doors is a crucial factor because these doors are specifically designed to prevent the spread of fire and smoke. Ensuring that fire doors are not obstructed allows them to function effectively in the event of a fire, allowing occupants to escape and reducing overall fire damage. Fire doors should be regularly checked to ensure they can close properly and form a secure barrier against flames and smoke, thereby contributing to the overall safety of a building.

While installing smoke detectors and checking for blocked fire doors are both essential fire safety measures, and training staff in CPR and gathering emergency contact information are important for overall emergency preparedness, they do not directly pertain to fire prevention in the same way as maintaining and ensuring the functionality of fire doors does.
