Functional safety activities are most effective by integration into a well-established and proven quality management system.
Building Risk Assessment
Building Risk Assessment (BRA) is a tool used to assess the risks to people in occupied buildings in the facility.
Escape, Evacuation and Rescue Analysis
Escape, Evacuation and Rescue Analysis ensures that the design of a facility is such that the risk to personnel is kept to within the ALARP region.
Functional Safety Assessment
Independent Management of Functional Safety Assessments, Audits & Support.
Functional Safety Lifecycle and Management
Functional Safety Lifecycle and Management is a key requirement demonstrating how Functional Safety is to be implemented and achieved.
Human Factors
Human factor assessment is a key area in identifying potential hazards which may be instigated by human errors.

Proof Testing is one of the main requirements to ensure that Functional Safety is maintained throughout the operational phase.
Operation and Maintenance
FSES can carry out review studies and provide consultancy to ensure Functional Safety requirements are maintained during Operation and Maintenance.
Quantitative Risk Assessment
Quantitative of Risk in terms of IRPA, PLL and graphical demonstrations such as FN Plots.
Reliability, Availability and Maintainability Study (RAMS)
Reliability, Availability and Maintainability Study (RAMS) is used as a decision making tool to increase the availability of the system, and thus increase the overall profit as well as reducing the life cycle costs.
Process Hazard Assessment (PHA)
FSES can provide Process Hazard Analysis (PHA) and HAZard and OPerability (HAZOP) study chairpersons. Our expert PHA facilitators hold certification in conducing HAZOP, HAZAN and CHAZOP.
