Chemical expert advice

Arson or accident? An analysis of fire debris samples can help answer the question of whether a fire was set with gasoline, alcohol, or another accelerant.

Caution: Poison! The FOR chemical advisors provide assessments at incident sites whether any liquids or gases released pose a threat to health or the environment.


The ZSAS also supports forensic investigations at locations where shots were fired throughout Switzerland. These activities include, among others:

  • Reconstruction of shot trajectories (3D reconstruction)
  • Shot distance determination using 3D reconstruction or smoke
  • Examination and assessment of weapons for their handling safety
  • Evaluation of traces of destabilization devices
