2.2.2 Areas especially endangered through 
human and technical failure 
Areas at special risk from fires 
Fires can act on facilities and buildings from within and from 
outside. They can destroy or damage all areas, or they may 
prevent further use due to the effects of smoke. Even small 
fires in exposed parts of facilities (e.g. IT) may lead to failure 
of the entire facility.
Areas at special risk from hazardous substances 
In addition to the primary risks of harm to the operating 
personnel and damage to the area surrounding the facility 
concerned, the release of hazardous substances may also 
induce explosions and fires. The further use of contaminated 
technical facilities, including IT equipment, may be 
impossible or restricted.
Areas at special risk from explosions 
Explosions can impact on facilities and buildings from within 
and from outside. They may damage or destroy all areas and 
induce chain reactions. The primary destruction results from 
the blast wave; the initial explosion is often followed by fires. 
Even small fires in sensitive areas (IT, power) may lead to 
failure of the entire facility. 
Areas at special risk from other physical impacts from 
inside and outside 
Physical impacts from inside and outside may impair the 
functional effectiveness of facilities or buildings and damage 
or destroy entire complexes. This can lead to breakdowns 
and failures in all areas. Physical impacts in the area of 
external networks can lead to internal supply shortages and 
production losses.

2.2.3 Areas especially endangered through 
terrorism and criminal acts 
The graduated risk categories indicating conceivable threats 
initially apply to the entire company. However, individual 
complexes within the overall company are also comprised of 
units or plant components which differ in terms of risk 
potential, design, form of usage, technical configuration and, 
above all, vulnerability to interference and malfunctions.
