AROS 3D – Consequence

Each piece of system / equipment unit / object identified on a site has an associated consequence should a release occur. The magnitude of the consequence of a release for each system / equipment unit / object describes the extent of damage to the site and / or the harm to personnel on site.

The magnitude of the consequences of a release are dependent upon:

• The driving force behind the release (i.e. how fast the material is released).
• The duration of the release (i.e. how long the release lasts).
• The type of material that is released (i.e. toxic, flammable, gas, liquid).
• The systems in place to prevent, control or mitigate the consequences (i.e. release detection systems, fire fighting measures etc.).
• The impact on the site (equipment / structure) and / or harm to personnel on site (i.e. escalation of the consequences, personnel injury / fatality).

In AROS 3D the consequences of a release and its ultimate impact is described over multiple input screens. Examples of the input data required is shown in the screen shots below.

AROS 3D Software Features

Dynamically add new, update or remove various consequence impact data including:

• system / equipment parameters (pressure, mass, volume etc.);
• safety systems effectiveness (isolation, emergency de-pressurisation, ignition probability etc.);
• personnel distribution by area and their time on site;
• asphyxiating, toxic, flammable, explosive material characteristics;
• escalation, personnel escaping and area, personnel evacuating the site rule-sets;

AROS 3D undertakes checks on key data to ensure that the input data is within specified limits and consistent with other input data.
