Lead in Paint Coatings

Although the inclusion of lead compounds in new paints is now prohibited, existing paint coatings may still contain a high lead content, especially if the coating is old or has been over-painted many times over a number of years. Therefore it is recommended that prior to any works being undertaken that involve the disturbance of paint coatings which are likely to contain lead, a full risk assessment is undertaken.

Lead is classified as a substance hazardous to health. Any works involving substances containing lead or lead compounds are legally required to comply with the Control of Lead at Work Regulations 2002 (CLAW).

The first stage of risk assessment is to sample the paint on site. The knowledge of the extent of lead within paint coatings will allow Clients to determine if paint coatings have to be removed using controlled conditions or if simpler and cheaper techniques can be used, and assists clients in their disposal of waste responsibilities.

Specification of works.
Information is required as to the extent of work on site such that representative sampling can be undertaken. Site visits by a 4-RAIL Services Consultant may be required to risk assess safe access to all required test surfaces.

The quantification of the lead content in the paint is undertaken by sampling the existing paint coating on site. 4-RAIL Services trained Technologists will attend site at convenient times to sample agreed locations.

Analysed in the laboratory to determine the lead content of the paint sample using Inductively Coupled Plasma Optical Emission Spectroscopy (ICPOES). Scanning Electron Microscopy (SEM) analysis of individual layers to confirm the presence of lead pigments.

Reports will bring to the attention of the Client any areas where lead has been identified, and suggest control measures to be taken. Where lead is identified, workplace exposure monitoring will be required to confirm the effectiveness of control measures implemented
