What system is used in the fire apparatus bay to draw exhaust outside the building?

The extractor exhaust system is specifically designed to remove harmful vehicle exhaust fumes from the fire apparatus bay and vent them outside the building. This system is critical for maintaining a safe environment within the bay, as the presence of carbon monoxide and other toxic emissions from the fire apparatus can pose serious health risks to personnel.

Typically, the extractor exhaust system works by using strategically placed ducts and fans to capture exhaust directly from the vehicles as they are started or operated within the bay. The system often relies on a network of flexible hoses or fixed ductwork that connects to the vehicle’s exhaust system, ensuring that contaminants are evacuated efficiently before they can accumulate in the workspace.

In contrast, while a ventilation system may circulate air within a space, it does not specifically target the removal of vehicle exhaust. Additionally, smoke removal systems are primarily designed for managing smoke produced during a fire, which is a different operational focus. An exhaust fan system could generally move air but lacks the specialized components and connection features required to handle automotive exhaust effectively, making it less appropriate for this specific application. Therefore, the extractor exhaust system is the most suitable and tailored solution for drawing exhaust outside the fire apparatus bay.
