Removing the paint and preparing the structure surface is labor intensive. That process also must meet containment and ventilation requirements for worker safety and environmental protection as well as requirements for hazardous-waste disposal. Worker safety Worker safety requirements are extensive. When a contractor accepts the job, it must develop educational and medical programs to prepare workers for the job. All employees must be trained in the hazards of lead-based paint as well as cleanup techniques and other procedures to ensure they follow all federal Occupational Safety and Health Administration regulations.
Employees are subject to medical examinations before, during and after the project.
No debris or any objects can escape from the work area. The steel main truss span of the bridge is 288 feet long and 50 feet deep. The containment plan will include building a rigid frame and covering it with tarps or panels made of aluminum or fiberglass. Special engineering analysis is required before installation. The ventilation system is necessary to move and clean the air in the work area.
