Methods for Removal of Lead Paint from Steel Structures

摘要

Because of the environmental problems leaded paint can create, regulations havebeen enacted to help protect the environment and the safety and health of workers. However, these regulations have had a significant impact on the cost of painting, on painting with leaded paints, and on the removal of these paints. New methods have been developed to deal with the removal of leaded paints, and the costs of these methods vary, sometimes considerably, with the structure involved and the removal method used. Many field personnel are not familiar with the issues involved with leaded paint removal, the options available, and costs. This report was prepared to provide information about the current regulations for the removal of leaded paints, new methods of paint removal, and the costs associated with these new methods. Coating removal methods discussed include: dry abrasive blasting, water jetting, water blasting with abrasive injection, power tool cleaning, and chemical stripping. Maintenance painting methods discussed include spot surface painting, hand or power tool cleaning, vacuum blasting, water blasting, and chemical stripping. This report focuses on leaded paint on steel structures; removal of leaded paint from other substrates may or may not be done by methods described here.
