System safety analysis and management

Mitigating hazards in technical systems

Through system safety analysis and management, AFRY provides improved health and safety performance, reduced cost associated with accidents and incidents and improved competitiveness in the marketplace.

For industrial and military systems, safety is paramount. To mitigate hazards within a given technical system for its entire lifecycle, System Safety is applied, using a selection of engineering and management methods.

Conventional safety assessment methods such as Preliminary Hazard Analysis (PHA), Fault Tree Analysis (FTA), Failure Modes and Effects Criticality Analysis (FMECA) and Functional Hazard Analysis (FHA).

In addition to hazardous component failures, accidents can also be caused by unsafe interactions of system components, none of which may have failed. An example of modern software-intensive systems which are difficult evaluate by conventional methods are autonomous vehicles.

Our deep competence and long experience help you identify, assess and mitigate hazards by applying safety as an emergent system property, requiring the necessary control structure to be analysed.

With reduced costs, associated with accidents and incidents, comes improved competitiveness in the marketplace in addition to improved safety to health, property and environment.

AFRY can assist in safety analysis in line with the following:

  • System safety handbook of the Swedish Armed Forces, either
    • H SystSäk 2011
    • H SystSäk 2022
  • FMV, the Swedish Defence Materiel Administration’s handbooks about more specific topics and applications for system safety, such as software in safety-critical applications, vehicles, electrical products and systems etc.
  • ISO 26262
  • MIL-STD 882
  • EU Directives, such as
    • 2006/42/EC (Machine Directive)
    • 2014/30/EU (EMC Directive)
    • 2014/35/EU (LVD Directive)
    • 2011/65/EU (RoHS 2)
    • 2014/53/EU (RED Directive)

We are also implementing the STAMP/STPA methodology, to complement the System Engineering approach to safety assessments for complex systems.

Machine Safety, Rail Safety, Nuclear Safety, Vehicle Safety

AFRY works broadly within the safety analysis area, and has extensive experience in adjacent areas, such as Machine safety, rail safety, nuclear safety and software safety. These areas have many similarities and cooperation is done company wide.
