How does OSHA investigate a construction accident?

OSHA will investigate a construction accident at the request of an employer or a worker for a contractor covered by the Occupational Safety and Health Act. Depending on the seriousness of the accident, OSHA may also conduct an unrequested investigation of a construction accident. 

OSHA gives advance notice of inspections only in cases where there is imminent danger to workers, inspections occur after business hours or require special preparation, management needs advance notice to attend the inspection, or more intensive inspections, like fatality investigations, are required. An authorized worker representative must accompany OSHA inspectors along with the employer’s management.
