Independent Functional Safety Consultancy

ProSalus can provide consultancy lifecycle services in the following 11 categories which align with the Functional Safety Lifecycle Framework in the good practice standards.

Functional Safety Assessment

Functional Safety Assessment (FSA) is a systematic review broken down into 5 stages (Stage 1 after initial Safety Requirements Specification (SRS) development, Stage 2 after detailed design, Stage 3 after installation and commissi...



Safety Requirements Specification

The Safety Requirements Specification (SRS) is fundamental to the design and validation of the safety-instrumented system. The SRS is developed during phase 3 of the Functional Safety lifecycle, and must be available throughout the...



Lifecycle Verification

Verification is the activity that confirms by analysis and/or testing that the required outputs satisfy the defined requirements for the appropriate lifecycle phases.



Hardware Verification

As part of the detailed design phase (phase 4) you are required to design the Safety Instrumented System (SIS) in accordance with the Safety Requirements Specification (SRS) so that the Safety Integrity Level requirements (SIL) can...



Software Verification

All phases of the safety lifecycle require to be verified. This is an activity that confirms that all required inputs and outputs of the phase meet the requirements of the lifecycle phase.



Validation

Validation is an activity, which demonstrate that the Safety Instrumented Functions (SIFs) and Safety Instrumented Systems (SISs) meet the requirements identified within the Safety Requirements Specification (SRS) after installation...



Functional Safety Compliance Assessment

Functional Safety Compliance Assessment (FSCA) is a systematic review of a component or system to determine its overall SIL capability based on the requirements of BS EN IEC 61508 2nd Edition.



Systematic Capability

Functional Safety Systematic Capability Assessment (FSSCA) is a systematic review of a component or system to determine its overall systematic capability based on the requirements of BS EN IEC 61508 2nd Edition.



Functional Safaty Gap Analysis

A Functional Safety Gap Analysis is the systematic review of a the organisations/projects systems identifying potential gaps in the system that can illustrate where additional work is required to assist in compliance to IEC 61508/61511.



Functional Safety Management

These are the systems used by an organisation to manage its activities to ensure that their functional safety objectives are accomplished.



Proof Test

The purpose of the proof test is to prove the safety instrumented system (sensor, logic solver and final element), operates as per the safety requirements specification and to identify any dangerous undetected failures.
