A key element of our service is an accurate survey of the asset and all potential hazards.
The physical investigation work scope is likely to include the following elements:
- The most likely areas requiring investigation will be ducts, filters, vessels, service runs, pipes, etc. The investigation will take the form of visual inspections and sampling work. The chosen sample point locations will have considered the access restrictions caused by the congested nature of the pipe runs and the potential for materials that contain asbestos being present.
- Accessing specific process pipes, services and facilities via a variety of methods which may include cold cutting.
- We will collect samples using swabs and specialist grabs depending on the particular area being sampled.
- Specialist independent and accredited laboratories will undertake analysis. This may include several laboratories depending on the complexity of the analysis, and KDC have established relationships with suitable laboratories.
The results will produce an updated hazard risk matrix within a detailed report. The hazard matrix is a live document easily updated from the initial desk study, following physical sampling results and during the actual decommissioning itself.
The report will include annotated drawings showing the locations of the sampling and any areas of concern. We will adopt a simple colour coding traffic light system. This will identify process plant items, which are:
Green – They need no further cleaning before decommissioning and we could recover items for scrap or for non-hazardous landfilling.
Amber – Some contamination may be present and may present a low risk for the decommissioning of the facility. They need some cleaning before dismantling or decommissioning.
Red – Deemed to be high risk and make up potential hazardous waste. Further cleaning is likely before dismantling or decommissioning.
The report will ultimately help produce a detailed Scope of Work document for the decommissioning of the facility.
