TUNNEL SAFETY TESTING, S.A. was founded in Spain in 2005.

Applus+ TST is an experimental and technological centre dedicated to carrying out real-scale fire safety tests in tunnels. The Applus+ TST facilities are located in Asturias, in the north of Spain. 

The facilities include a 600-meter long tunnel that allows to test a number of different products under real fire conditions:

  • Ventilation systems and equipment
  • Fire detection and extinguishing systems
  • Components and construction materials for tunnels

Additionally, Applus+ TST has two test benches for high-temperature fans, an immersion furnace for small and medium fans, and a recirculation furnace capable of testing fans up to 3.5 meters in width. 

Applus+ TST also has more than 10 years of experience training firefighters, mine-rescue units and other emergency personnel to handle fires in tunnels and underground shafts.
