Hazards and endangered areas 
2.1 Hazards 
The hazards facing operators of critical infrastructures can be 
broken down into (2.1.1) hazards relating to natural events, 
(2.1.2) hazards relating to human error or technical failure 
and (2.1.3) hazards relating to terrorism or criminal acts. In 
this connection it is to be noted that an entire facility or 
security-critical parts of a facility may also be affected by 
events outside of the actual facility, in neighbouring 
operational areas or traffic facilities to which a special threat 
potential applies (domino effect). Possible impacts in this 
respect include the spread of fire from neighbouring facilities, 
flying debris after an explosion in neighbouring facilities, the 
failure of supplies after catastrophic events outside of the 
facility, etc. Events occurring within a short time of each 
other
, such as a second, delayed explosion or several 
incidents occurring around the same time 
at different 
locations, may also entail an exponential effect by preventing 
rescue or restoration measures or causing resources to be 
concentrated in the wrong place, for example (diversionary 
measures
).
