We are expanding our network of independent Stack Emissions Monitoring Technical Assessors to support accreditation and surveillance of stack emissions monitoring and sampling, including MCERTS and Continuous Emissions Monitoring Systems.
You will assess the technical competence and consistency of organisations undertaking these activities against ISO/IEC 17025, MCERTS requirements and relevant methods and standards. Assessments include desk reviews, customer site visits, witnessing sampling activities and post-audit reviews.
This is a flexible, remote role with travel to customer sites.
What We’re Looking For
We are looking for experienced stack emissions monitoring professionals with extensive hands-on expertise and sound technical judgement. You should be confident questioning technical decisions and evaluating how organisations apply sampling methods and technical controls in practice.
You will need a relevant degree or equivalent, typically in chemistry or a chemistry-related subject. Current or previous MCERTS Level 2 personnel certification, with all four technical endorsements, is expected for MCERTS stack sampling activities.
Your technical expertise should cover:
- Working knowledge of ISO/IEC 17025, the MCERTS performance standard for stack emissions monitoring, BS EN 15259 and BS EN 14181.
- UK and European Standard Reference Methods, US EPA Methods and Environment Agency guidance, including the index of methods and Method Implementation Documents.
- Practical proficiency in isokinetic and low-volume sampling, velocity measurement, and online gas sampling and analysis.
- Gas analysis techniques including non-dispersive infrared (NDIR), chemiluminescence, paramagnetic analysis, flame ionisation detection (FID) and Fourier transform infrared spectroscopy (FTIR).
- Practical experience in gravimetric and chemical analysis.
You will be able to evidence:
- Understanding monitoring and sampling strategies and the appropriate application of published methods, with experience overseeing equipment, sample handling and personnel competence.
- Critically reviewing technical documentation, records and evidence to reach independent, well-supported judgements.
- Producing clear, concise technical reports.
Typical Backgrounds
You may be an MCERTS Level 2 team leader, technical or quality manager, sampling or emissions monitoring specialist, Continuous Emissions Monitoring Systems specialist, or senior stack sampling practitioner. Your experience should combine practical expertise, senior technical or oversight responsibilities and sound knowledge of ISO/IEC 17025, gained in a monitoring organisation, testing laboratory or environmental monitoring setting.
