Our Engineers can work as part of an integrated team through our Functional Safety Consultancy services or provide complete Safety Instrumented Systems.


With our skills and expertise in delivering systems from a single stand alone safety loop to multiple Integrated Control Safety Systems (ICSS) controlled via a safety PLC, HTS Safety Solutions can tailor an appropriate package.


Functional Safety Life Cycle management is the key objective to achieving compliance within the frame work of IEC 61508. Managing Functional Safety in accordance with the 61508 group of standards will show that: -

  • The Company has a clear safety policy
  • Appropriate techniques and measures are in place
  • A Clear organisation structure is in place
  • Non-conformance is identified
  • Systems and processes are auditable
  • Safety planning is in place

Implementing the Functional Safety Lifecycle ensures that the requirements for functional safety are met and that any new or modified safety systems are designed, installed and commissioned correctly. HTS Safety Solutions follows the life cycle approach and fully supports the methods employed for the various phases we work in.


Our core skills in HTS Safety Solutions lie within the realisation phases four and five of the life cycle for both hardware and application software. Additionally we are able to support or deliver the determination phases one, two and three through partnerships.
