This paper takes a look at emerging environmental, health and safety issues that may impact painting contactors and facility owners. Specific topics include a summary of OSHA and EPA’s new and proposed revised regulations related to lead, paint, and construction. Information will be provided on EPA regulatory actions related to NAAQS Lead and the recent advanced notice of proposed rulemaking for Lead, Renovation, Repair, and Painting Program for Public and Commercial Buildings.

Much of the information is taken directly from the respective agency’s published regulatory agenda, supplemented by anecdotal information gathered from various professional journals, seminars and conferences.
Reinforced concrete structures are subject to many types of deterioration. Many of these are visible; however, one that is not is the crevice corrosion that occurs internally at the reinforcing bars. To detect, mitigate and delay this type of insidious corrosion, a form of cathodic protection in the form of thermal sprayed coatings will be discussed. To implement this as a corrective action as well as a preventive action is the theme of this paper.

Coating technologies for bridges has not changed much since 1977. Available finish coat technologies were limited to alkyd, acrylic, or urethane-based chemistry. Performance of these chemistries has declined over the years due to cost reduction in paint to meet project pricing requirements. Bridge owners and engineers have had a limited selection of high-performance coatings to protect their assets. This is even more important with high profile structures where the finish coat needs to stand the test of time and limited maintenance funding has forced asset owners to extend time in between cosmetic maintenance
