Code 5037 applies to employers painting metal structures exceeding two stories in height.  For commercial structures, a “story” is defined as being 15 feet in height.  Employers remove the old paint and/or rust (if necessary) by means of abrasive blasting.  Some employers prepare and completely enclose the structure or bridge to capture any contaminated waste such as lead and rust.

The painting of metal skeleton framework of buildings exceeding two stories, steel smokestacks, metal towers for power lines, radio and television stations, aircraft beacon towers and observation towers is also contemplated by this classification.

Additionally, this classification applies to painting metal bridges of any size.  The metal structure of the bridge is sandblasted to remove any old paint and rust.  The employer then applies a primer and a coat of paint is then applied to the structure.  This classification applies whether the procedure is conducted from a scaffold or on the roadway of the bridge.  The installation of scaffolding or platforms is inclusive under this classification only if in conjunction with the metal structure or bridge painting operation.
