Regardless of exemptions, what is one type of incident that all companies must report to OSHA?

One type of incident that all companies must report to OSHA is fatalities that occur in the workplace within 8 hours of the event. OSHA mandates that employers notify them of any workplace incidents that result in employee deaths. This requirement is critical as it enables OSHA to investigate potentially hazardous situations and implement measures to prevent future incidents. Reporting fatalities promptly ensures that safety issues are addressed efficiently and can lead to improvements in workplace safety regulations and practices.

The other options do not fall under mandatory reporting requirements by OSHA. Employee promotions, safety training sessions, and workplace surveys are not incidents that need to be reported, as they do not directly relate to employee injuries or fatalities. Consequently, they are part of the broader management and operational aspects of a company but do not trigger OSHA's reporting requirements.
