Ventilation and Equipment
The Deck Park Tunnel was designed to be ventilated naturally, using the car's energy to help propel air through the tubes. In times of heavy traffic or in the event of a fire in the tube, each tube has four backup fans that provide ventilation, in order to prevent the dangerous buildup of carbon monoxide.
The tunnel has a large diesel generator approximately 50 meters east of the westbound entrance to the tunnel, ensuring that the lighting, video surveillance, and intercoms have continuous power even during an outage. For the safety of motorists, intercoms are located every 150 feet (46 m) within the tunnel.

Famous quotes containing the word equipment:
“Dr. Scofield’s equipment, which you have just seen, radiated waves direct to Professor Houghland’s laboratory. When these waves came in contact with those the professor’s equipment was radiating, they created the interstellar frequency, which is the death ray.”
—Joseph O’Donnell, and Clifford Sanforth. Arthur Perry (Bela Lugosi)
