Paula Jefferson, head of Beachcroft LLP's Disease Group, said: "Any organisation involved in any activity in the future, where there is the potential for release of harmful substances in to the atmosphere, should ensure that they have taken all necessary steps to identify the potential contamination and to then ensure that they either employ, or have themselves the necessary skills, to deal with that contamination. The principles in the judgment apply not just when there is demolition in progress, but to any activity where there is potential for exposure in to the atmosphere. Where there is any known potential for such exposure, then regard should be had to not just the onsite workforce but also to those living and working in the surrounding area. In the Corby case the area of risk was 4km from the demolition site. The area for potential exposure will clearly vary depending on the circumstances of each case. In essence, the message remains the same - proper risk assessment is key and must include identifying the appropriate people to do the job and not cutting corners, which, as has been proved for Corby Borough Council, is likely to be false economy."
