Testing for Lead
The purpose of testing for lead is to identify the risk and develop appropriate controls that enable the safe removal and disposal, a lead survey may also include demolition waste materials, soil, dust, water and general debris. The process is quite simple a surveyor will extract a sample and record the location, analysis will be undertaken by an UKAS accredited laboratory where the results documented on a certificate of analysis.
There are other methods to test for lead but these are not as conclusive and unreliable compared to laboratory testing.
Removal of Lead
Removal methods would include controlling the working environment by erecting a respirator zone or an enclosures with continuous negative pressure. There are four common methods that can be used to safely remove lead paint:
- Abrasive paper – for small volume removal for all types of surfaces.
- Pneumatic scaler – for more intricate surfaces.
- Chemical – application of a paste that formulates the lead into hydroxide, ideal for all types of surfaces that can easily remove several layers of lead paint.
- Quilling – shot blasting inside a controlled environment.
All debris will be treated as hazardous and disposed and transported in a controlled way, the waste will also be subjected to the Hazardous Waste Regulations where an Environmental Agency Hazardous Waste Consignment note provided.
