A reader passed long this photograph of workers assembling scaffolding outside a building on West 37th Street. He was also troubled enough by the sight of the workers, eight stories above the street, not wearing harnesses and are walking on unsecured boards that he called 311.

We're checking with the Department of Buildings on whether this kind of work is allowed—the DOB has been aggressive in improving safety standards and encouraging construction workers and companies to use harnesses.
