Sammanfattning: This study compares the health aspects of lead oxide paint and the technical effects of the material used on steel profiles. The purpose of the study is to give recommendations about how to treat the older beams coated with the paint practically and according to the Swedish law and recommendations. The Swedish Work Environment Act and the Environmental Code as of 2022 has been reviewed to find any legal basis that the paint has to be removed. Although the law recommends the use of alternative, non-toxic materials, it does not prohibit the use of them if necessary. The use of materials which can cause injuries to one’s health should be evaluated, regarding the work environment, and the workers that will be exposed to the substance. Apart from the laws, studies have also been carried out at the library, in Swedish Standard Institute reports, in charts from early 1900s, and current charts of dimensions and characteristic values of the steel components. This resulted in the conclusion that reuse of steel is encouraged and there are ways to verify the serviceability of the components. Lead is toxical to humans, animals, and the environment if exposed in larger amounts or for a long period of time. Lead oxide in paint is one of the most effective corrosion inhibitants today and is still sold to professionals.
