ITRS: Exposure
Defined by the consequences of a fall off the trail

Normal injury risk
-
Trail is not exposed in a way that a fall would have more severe consequences as it anyway has.
-
There are also no sections that are exposed but secured by safety nets to mitigate the consequences of a fall, so you will not feel vertigo.




High risk of serious injury
-
A fall in such terrain carries a high risk of serious injury
-
Examples: steep forest or meadow terrain below the trail, where one can stop a fall; or a 2 m high vertical drop directly next to the trail.
-
There can be sections that are more exposed but secured by safety nets, so you may feel vertigo.

Life threatening consequences
-
A fall in such terrain is life threatening
-
Examples: steep terrain below the trail passing into a vertical drop further down, but you have a chance to stop yourself falling; or a 4 m high vertical drop directly next to the trail.

Fatal
consequences
-
A fall in such terrain is fatal
-
Vertical drop right next to the trail without any possibility to stop your fall.




The most exposed section of a tour determines the exposure rating of the whole tour.
The width of the trail does not influence the exposure rating.
