OSHA records or official release confirm that the investigation was opened on July 29, 2025.
The U.S. Department of Labor (OSHA) says in its Feb. 10, 2026 news release that "An investigation was initiated on July 29, 2025" after the explosion at the Horizon Biofuels facility in Fremont, Neb. Independent reporting (Nebraska Public Media, KETV) and the U.S. Chemical Safety Board's investigation materials document the July 29, 2025 explosion and the subsequent federal probes, corroborating OSHA's timeline. Verdict: True — OSHA's own DOL press release (a primary source) explicitly gives July 29, 2025 as the date the investigation began, and contemporaneous reporting/CSB documents support that date.
