Introduction
This chapter provides an introduction to the AADvance Safety Manual and to
the AADvance system.
Verification of the Safety
Manual
The AADvance system and the user Safety Manual are certified by an
independent certification body to meet the requirements of IEC 61508 SIL 3.
Competency The achievement of functional safety requires the implementation of the safety
lifecycle whilst ensuring that persons who are responsible for any safety
lifecycle activities meet the required competency levels in functional safety.
All persons involved in any safety lifecycle activity, including management
activities, shall have the appropriate training, technical knowledge, experience
and qualifications relevant to the specific duties they have to perform. The
suitability of persons for their designated safety lifecycle activities shall be
based on the specific competency factors relevant to the system application and
shall be defined and recorded for each individual.
The following competence factors should be addressed when assessing and
justifying the competency level of persons to carry out their duties:
• Engineering experience appropriate to the application area
• Engineering experience appropriate to the technology
• Functional safety engineering experience appropriate to the technology
• Knowledge of the legal and safety regulatory framework
• The consequences of failure of the safety-related system
• The safety requirements class of the safety-related systems
• The novelty of the design, design procedures or application
• Previous experience and its relevance to the specific duties to be
performed and the technology being employed
In all of the above, the higher risk will require increased rigor with the
specification and assessment of the competence.
