The third (recommended step) is to define impacts by adding these from the included relevant Scenarios. Alternatively, the impacts can be added and then linked to the scenarios.

It should be taken into account that one impact can be linked to several scenarios. Hence, the user can link relevant scenarios to any existing impact.

The impacts can be linked to areas, rooms and facilities, which should be the same as those linked to the scenario.

The impacts can be classified as having impacts inside, outside or inside and outside.

The impacts can be classified as one of the types for which SAFRAN supports quantification (See Table 1) or as OTHER. For the impact supported by SAFRAN, tables for quantification of the impacts will be added by SAFRAN. For impacts classified as OTHER, user-defined tables can be added (one such table for each impact). Note that for any impact the user can add any number of tables as attachments with the purpose of documentation.

All impacts can be assessed qualitatively or quantitatively as described in the SAFRAN Manual for Calculations.

Table 1. Classification of impacts in SAFRAN

Where the impact affects Typeof impact. * - SAFRAN supports quiantification Quantitative or qualitative
Inside Releases to air* Quant. and Qualit.
Inside Increased external exposure* Quant. and Qualit.
Inside OTHER* Quant. and Qualit.
Outside Releases to air* Quant. and Qualit.
Outside Discharges Quant. and Qualit.
Outside OTHER Quant. and Qualit.
Inside and outside Releases to air* Quant. and Qualit.
Inside and outside OTHER Quant. and Qualit.

Note: When a new impact is added, SAFRAN shows it as undefined since it does not know what type of impact it is. The impact will be shown as undefined until all required properties have been defined.
