There are several safety standards that are outlined by the United States Department of Labor Occupational Safety and Health Administration (OSHA) in order to prevent a potential construction site accident. There is also an independent committee called The Advisory Committee on Construction Safety and Health (ACCSH) that provides additional information on construction safety issues. OSHA also provides training programs for both supervisors and workers in the construction site to make sure that they are all aware of the hazards at work and be able to avoid them. All in all, they have guidelines, safety training, approved PPEs for almost all kinds of workplace.
