Area Re-classification (DSEAR/ATEX)

Client: Cognis, Hythe

The Brief

An established top tier COMAH site had been advised by the HSE to review their hazardous zones in line with a modern code of practice. Previously, the site had relied upon a corporate guideline from a previous owner. This was now considered to be out of date and unsupported.

The Challenges

The project scope was extensive and required careful co-ordination and scheduling with site teams. A number of non-standard operations required individual calculation to identify the size and shape of the hazardous zone.

The Response

The entire site was broken up into production areas and reclassified. The work required the identification of all leak sources, an assessment of the grade taking into account frequency and ventilation and the preparation of zoned drawings.

The Results

BPE were able to complete the required assessment and classification work but also, very importantly, to provide practical solutions for a number of identified issues. The project was successfully completed to meet the defined review specified by the HSE.
