We have added a new resource to our OSHA Publications page.
OSHA Fact Sheet: Safely Performing Hot Work on Hollow or Enclosed Structures in Marine Terminals was released earlier this month. It defines hollow or enclosed structures and lists some examples, identifies some hazards and sources of flammable or explosive atmospheres workers may encounter when working with these, and describes the obligatory control measures employers have to keep workers safe during hot work on these structures.
