The guidance is advisory in nature, informational in content, and is intended to help construction workers and supervisors understand and reduce noise exposure on job sites. Employers are required to comply with safety and health standards as issued and enforced by either the Federal Occupational Safety and Health Administration (OSHA), or an OSHA-approved State Plan. In addition, Section 5(a)(1) of The Occupational Safety and Health Act, the General Duty Clause, requires employers to provide their workers with a workplace free from recognized hazards likely to cause death or serious physical harm. If you are a construction worker, this pocket guide is written for you. Small contractors should also find this information helpful.
