THE REMOVAL OF LEAD-BASED PAINT FROM BRIDGES AND STRUCTURES

Lead-based pigments have been used in paints for many hundreds of years, with their use as corrosion inhibitive pigments commencing around 1880. This period coincided with an escalation in the construction of iron and steel bridges as transport networks expanded throughout developing countries. Red lead pigments were used in large volumes for this purpose until the adoption of zinc metal pigments in the early 1960s. Other anti-corrosive pigments containing lead included calcium plumbate, lead chromate and lead silicochromate. The Department of Transport in South Australia is responsible for the maintenance of approximately 320 steel bridges, many of which are coated with lead-based paints. The removal of the lead is the major concern, as blast cleaning, in particular, produces a very fine dust which is the main source of health and environmental problems. This report aims to discuss the various methods of treatment, and proposes guidelines for the safe removal of lead on the basis of current local and overseas experience. (a)
