Description of the Fire safety concept of the reference status  
The reference situation is usually the actual status.  
Description of the Fire safety concept of Variant 1.  
Variant 1 describes usually the proposed improvements, e.g.  automatic fire detection + fire proofing  
Description of the Fire safety concept of Variant 2.  
Variant 2 can be used for an alternative proposition, e.g. sprinkler protection

Proposed Fire protection concept, based on Ro  
 of  "Reference"  Install sprinklers  
Info on Ro    
0 Use manual fire protection  
1 Add automatic fire detection  
1,6 Install sprinklers    
2,7 Sprinklers with improved water supplies  
4,5 Too hazardous: reduce risk  

Use of the orientation value Ro, the Initial Risk.
To find the most efficient protection, the easiest way is to define an adequate level of protection for the property,  adding supplementary protection for the people and the activities if required.
  To facilitate the choice, one can now calculate the orientation value of Ro, the initial risk, with the values of P, A and the structural fire resistance Fo.
