The significance of my experience in ECETOC is illustrated by the following excerpt from Wikipedia

A scientific, non-profit, non-commercial and non-governmental association; established in 1978, ECETOC's main objective is to identify, evaluate, and through such knowledge help industry to minimise any potentially adverse effects on human health and the environment that may arise from the manufacture and use of chemicals, biomaterials andpharmaceuticals. Counting as its members the leading companies in the manufacture and use of chemicals, ECETOC facilitates the networking of suitably qualified scientists from its member companies and academia and co-operates in a scientific context with international agencies, governmental authorities and professional societies.

ECETOC is governed by a Board of Administration which is responsible for the overall policy and finance of the organisation and appoints the members of its Scientific Committee which defines, manages and peer reviews the ECETOC work programme. The outputs of its work programme are manifested as published reports, papers and specialised workshops.

In recent years, ECETOC has played a key role in advising regulators during the introduction of European regulations on the production and use of chemical substances, see Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH).

Of particular note are the Targeted Risk Assessment Tools developed by ECETOC which use a tiered (step by step) approach for calculating the exposure to and risks from chemicals that might reasonably be expected in defined circumstances of use. The approach addresses exposure to consumers, workers and the environment.


I have consideable experience in designing, implementing and auditing quality management systems in the ISO-9000 series. I operate these principles in my methods for producing expert reports, though I have not submitted my methods to a certification body. My methods ensure that my reports are robust and, where applicable and possible, quantitative. Expert Witness  2 page illustrates this in relation to the handling of medical records
