The Occupational Safety & Health Administration (OSHA) establishes guidelines to ensure worker safety, including those for entering a collapsed structure . According to OSHA, in the event of a building collapse, an Incident Command System will be established for management of the site. This may include appointment of a safety officer, who is responsible for overseeing the safety and health of all responders, assuring the practice of optimal safety and injury prevention, investigating and documenting all response team injuries and illnesses, and other duties.
