Since 2008

To Regulators / OEMs / End-users
Hazard Analyses
Hazard Analysis, being a very early phase in the safety lifecycle - it is paramount to get it right.
A comprehensive Hazard Analysis of a run-of-the-mill system is generally achievable with the appropriate mix of Designers and End-users in the team. Whereas Hazard Analyses of large, complex or socio-technical systems or a combination of such quite often become matters of conjecture. A question you often hear is: Have you considered all possible hazards? We use Systems Engineering methods like STPA to study novel and complex systems leading to all-encompassing analyses providing exhaustive lists of hazards and hazardous scenarios to work from in the next phases of the safety lifecycle.
Quantitative Risk Assessments
We are passionate about assessing risk quantitatively and generally start with the Tolerable Risk. Having used these techniques since 2008, we have honed our skills and specialise in quantifying Safety Integrity Requirements.
Be it Individual or Societal risk, we have the tools and the skill sets to conduct Safety Integrity Level (SIL) Determination arriving at numbers that we can defend rather than use qualitative risk matrices.
Safety Integrity Verification
We conduct Safety Integrity Verifications - both hardware and systematic
according to the requirements of IEC AS 61508 / 61511 / 62061 or ISO 13849 and arrive at their SIL or PL respectively employing appropriate techniques:
- Reliability Block Diagrams RBD
- Failure Mode Effects & Diagnostics Analysis FMEDA
- Fault Tree Analysis FTA
SIL beyond the numbers
Most accidents are not the result of unknown scientific principles but rather of a failure to apply well-known practices, systems and procedures.
It is necessary to have in place and be able to demonstrate that the management activities, systems and procedures are appropriate and that there is adequate competence for carrying out each task.
We facilitate setting up of Functional Safety Management Systems according to the requirements of IEC AS 61508 and undertake third party audits on existing procedures and techniques to determine their potential for adequacy.
