What is the purpose of a smoke ejector or high-volume fan on a fire scene?

• A. To increase the temperature inside.
• B. To pressurize the attic.
• C. To remove smoke and heat, improving visibility and reducing hazardous conditions inside the structure.
• D. To supply oxygen to fuel.

Answer: (C)

The main idea is to move large amounts of air to remove smoke and hot gases from a structure. A smoke ejector or high-volume fan pulls the smoke out, lowers the heat, and creates clearer air, which improves visibility for firefighters and reduces hazardous conditions inside the building. This ventilation helps make interior operations safer and more effective, especially during search and fire control. It does not aim to increase temperature, pressurize the attic as the primary goal, or supply oxygen to the fuel—the latter would actually feed the fire, not control it.
