2. SAFETY PRINCIPLES
2.1 INTRODUCTION
This paragraph provides an overview of generic safety principles with emphasis on the
system integration process. These principles are applicable to all safety-related
systems, including, but not limited to, the 8000 series system.
2.2 SAFETY MANAGEMENT
A prerequisite for the achievement of functional safety is the implementation of
procedural measures applicable to the safety lifecycle; these are collectively referred to
as a Safety Management System. The Safety Management System defines the
generic management and technical activities necessary for functional safety. In many
cases, the Safety Management and Quality systems will be integrated within a single
set of procedures. It is highly recommended that the integrator have a quality
management system in accordance with ISO9000.
The safety management system shall include:
• A statement of the policy and strategy to achieving functional safety.
• A Safety Planning Procedure. This shall result in the definition of the safety
lifecycle stages to be applied, the measures and techniques to be applied at
each stage, and responsibilities for completing these activities.
• Definitions of the records to be produced and methods of managing these
records, including change control. The change control procedures shall
include records of modification requests, the impact analysis of proposed
modifications and the approval of modifications. The baseline for change
control shall be defined clearly.
• Configuration items shall be uniquely identified and include version
information, e.g. system and safety requirements, system design
documentation and drawings, application software source code, test plans,
test procedures and results.
• Methods of ensuring that persons are competent to undertake their activities
and fulfil their responsibilities.
Expansion of these requirements is included within the following sub-paragraphs.
