Safety Engineering

Serving highly regulated industries and applications


At Westley Lansdowne, being dyed-in-the-wool Safety Engineers,  we understand the critical role that safety engineers play in safeguarding lives and ensuring availability of critical infrastructure and systems. With our breadth of safety engineering experience we can develop solutions tailored specifically for your needs. We are committed to providing you with the expertise and support necessary to achieve the legal or industrial standards you seek to  meet. Whether you're seeking strategic planning, specific risk assessments, requirements development and substantiation,  compliance audits or incident investigation support, we're here to help you navigate the landscape of developing complex products, systems or services. Explore our offerings and join our satisfied client base who have trusted us to enhance the safety of their critical capital projects .

Our Approach

Safety Engineers support the design, development and certification of complex systems.

Safety Engineers analyse concept and/or detailed designs and provide advice on the design and operation of equipment, systems or processes where the law requires specific standards to be met – be these probabilistic, prescribed measures or goal-set criteria such as the ‘So Far As Reasonably Practicable’ principle within UK law. 


Safety Engineering is often focussed around maximising a design’s availability and tolerance to failure against a specified cost / delivery time constraint; often utilising defined standards to do this (such as BS EN 61508). 

Safety Engineering work tends to fall into two major types...

  1. Those that know they need help and,
  2. Those that don’t think they need help until later. 

The former is usually the classic ‘high-integrity’ industries – Nuclear, Aerospace, Automotive, Rail, Marine, Defence, Process industries, Oil and Gas for a start – and these often know roughly what they want sufficient to allow competent providers like ourselves to be instructed at the earliest convenience to align with the programme. 


The latter however encompasses a slighter wider variety of dutyholders within other industries who often become aware of the need to engage in safety engineering activities as a result of the compliance requirements involved with a new facility being developed or a significant site / process change. Another favourite participant within this group is smaller firms supplying into ‘high-integrity’ industries – particularly Nuclear, Rail and Defence – where these firms are not used to developing equipment / services to the norms of these industries. 


The general advice is, if you think you might need our help, give us a call – we’re happy to discuss your issues and help you solve them if we can. 

We have practitioners with experience in the Nuclear, Aerospace, Automotive, Rail, Process and Defence industries on staff.

The sorts of activities we have previously supported include: 

  • Specification and Development of Safety Instrumented Systems 
  • Safety Case / Reliability Performance Justification Authoring 
  • Failure Reporting, Corrective Action and Monitoring System Management 
  • Production and Review / Approval of Safety Documentation 
  • Review of 3rd party documentation 
  • Safety Process Development, Deployment and Improvement 

Programme Management: 

  • High level safety strategy development
  • Scheduling / Programme Management of safety activities to deliver safety strategy 
  • Programme Monitoring and Control 

Safety Analysis Methods: 

  • Hazard Identification 
  • Hazard Assessment – Deterministic Methods such as HAZOP 
  • Hazard Assessment – Probabilistic for High Consequence Hazards 
  • Hazard Assessment – Deterministic for Low Consequence Hazards 
  • Safety Integrity Level Targeting 
  • Safety Integrity Level Verification

We can help fulfil your requirements in whatever way best suits your requirements – we can provide staff on a full-time, part-time basis or based on an agreed, costed statement of work – for a specific item of work or for more generalised support within a wider programme. 


Safety is built off known Reliability.

Our practitioners have experience in Reliability Engneering too.


The sorts of activities we have previously supported include: 


Reliability Analysis Methods: 

  • Fault Tree Analysis
  • Event Tree Analysis
  • Weibull Analysis 
  • Reliability Block Diagram development 

Reliability Growth: 

  • Highly Accelerated Test Planning and Deployment

Engaging with Westley Lansdowne

An engagement would begin with a discussion – we need to know what you want, ideally how or why you think we can help (occasionally needs in the field can be quite niche and outside of our experience – like Consequence Modelling) – from which we can develop a statement of requirements and a basis for quotation against. 


Note that we do not entertain Inside IR35 work at present, nor Outside IR35 based on thinly veiled contracts – all of our contracts are independently reviewed for compliance against IR35 where appropriate.
