Hot smoke caused a second fire to start, in a group of trucks apparently carrying paint and turpentine approximately west of the original fire. After this, the tunnel ventilation system was turned to full exhaust and full supply in order to extract smoke and reduce the likelihood of other spontaneous ignitions. New Jersey firefighters succeeded in extinguishing the second fire, and cleared a path for emergency vehicles to the first fire site where they linked up with the New York firefighters.
