  • Approach via loading dock entrance off Ter Huen Dr, bearing to the right. Note hydrant on left. During the day, area is congested with cars. The first door on the left might be a good choice for initial line placement on a well involved fire. Also plastic skylights on roof for ventilation. (See arrow)
  • Outside entrance to trailer. Note FD connection on left. In the event of a large fire, consider utilizing the door on the left for initial line placement.
  • Emergency electrical shutoff located on right side of trailer. SECURING ELECTRICITY DOES NOT DE-ENERGIZE THE MAGNET.
  • Vent for helium gas in the event that the magnet has to be “Quenched” in the event of an emergency. Located on rear of trailer.
  • Emergency quench button
