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 Assesment

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 t...

Lifecycle Verification

Verification is an activity, where by analysis and/or testing of the required outputs from each phase of the lifecycle can be done to ensure that they meet the phase and clause requirements defined within specified industry guidel...

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) ca...

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. This is critical in terms of software fo...

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 installati...

Functional Safety Compliance Assesment

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 Safety 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/...

Functional Safety Management

These are the systems used by an organisation to manage its activities to ensure that their functional safety objectives are accomplished. The objective of having a compliant functional safety management system is to ensure tha...

Proof Test

The purpose of proof testing is to confirm is through pre-determined regular physical testing that all elements of the safety instrumented system (sensor, logic solver and final element), diagnostics and software operate as per th...
