A manager must contact OSHA, the Occupational Safety and Health Administration, when there is a serious employee injury because it is imperative to report incidents that could indicate a life-threatening situation or serious safety violation. OSHA requires employers to notify them in cases of workplace incidents that result in fatalities or serious injuries that require hospitalization, amputation, or loss of an eye. This reporting not only complies with legal obligations but also plays a critical role in ensuring workplace safety and initiating necessary investigations that can prevent future incidents.

The other scenarios, while potentially concerning, do not meet the criteria that specifically mandate OSHA notification. For instance, a decline in employee productivity may suggest underlying issues but does not necessarily indicate an imminent safety hazard. Safety complaints should typically be addressed internally first, allowing the organization to resolve them before considering external reporting. Equipment failures, while important to address for safety, do not require OSHA involvement unless they result in a serious injury or present an ongoing risk that affects employee safety.
