Vehicle accident 
Hazardous substances could be released or important parts 
of facilities could be damaged or destroyed as a result of 
road or rail traffic accidents. Examples here include leaking 
drums resulting from fork-lift accidents, derailing of tank 
wagons, destruction of facilities by lorry impact. 
Interference using simple tools 
This category covers intentional interference, usually of a 
spontaneous nature, in important parts of facilities, using the 
tools and resources which are available at every plant. 
Examples here include smashing glass parts of a plant, 
clamping moving parts of a plant or adding prohibited

substances or materials to the process. Company employees 
are the primary suspects here. 
Interference using heavy tools 
The planned violent destruction of parts of a plant is 
assumed for the purposes of this interference option. 
Possible tools employed in such attacks include crowbars, 
electric drills, flame cutters, bolt cutters or sledgehammers. 
Examples of such attacks include breaking open doors and 
subsequently destroying facilities, smashing up 
measurement and control facilities and smashing open 
containers and piping systems, resulting in large-scale 
leakages. Instead of a specific attack, vandalism may also 
occur, e.g. out of anger following a failed break-in.
 
Arson using simple resources 
Simple resources cover ignition with matches, lighters or 
cigarette ends. This interference option thus only applies 
when sufficient quantities of combustible, highly inflammable 
materials are available. Examples here include igniting 
combustible liquids from a process, setting fire to storage 
locations to release hazardous substances, setting fire to 
peripheral rooms or facilities with subsequent impacts on 
important plant components.
