Slowly progressing or continual chains of events are thus not con-
sidered as emergencies unless an incident occurs suddenly or if
there is an impending risk that an incident will occur suddenly,
that the incident can be anticipated to occur at an approximate
point in time and that the incident is concrete. That there is an
impending risk of an emergency occurring entails both substantial
probability that the emergency will occur and substantial proba-
bility that it will occur in the near future. Examples of situations
when a municipal structure for providing rescue services does not
normally take action can be in the event of structural damage to
buildings caused by earth movement or erosion. The obligation to
take action primarily arises only when there is an impending risk
that a building will collapse or when erosion will obviously cause
a landslide, or after a collapse or landslide has occurred.Maintenance work is being carried out in a silo but the stipulated safety
equipment against falls is not being used. There is a considerable risk of
somebody falling and being seriously injured, but it is impossible to say
when this may happen. There is not an imminent danger of an incident
or accident that would warrant an emergency response operation. But if
somebody were to fall, there is a likelihood of it resulting in a response
operation. This type of rescue work can require special equipment such as
a lowering device or protective breathing equipment.
