Attic fires are generally classified as:

Attic fires are typically classified as ventilation-limited fires due to the unique environment found in attic spaces. These areas often have restricted access, limited airflow, and are insulated with materials that can ignite easily. As a result, the fire's growth is heavily influenced by the amount of oxygen available. In a ventilation-limited scenario, the fire can reach a stage where it cannot grow any further because of insufficient oxygen, which can lead to a rapid increase in smoke and heat if ventilation is introduced.

This classification highlights the need for careful ventilation strategies when dealing with attic fires. Firefighters must be aware that opening access points can significantly change the dynamics of the fire, potentially leading to flashover if not managed properly. Understanding the characteristics of attic fires as ventilation-limited is crucial for ensuring the safety of both the firefighters and occupants, as well as effectively controlling the fire.
