Perm Polytechnic Test Accident: Injury Toll Revised to Three

Authorities have opened a negligence case that points to a turbine wheel failing under load during third‑party testing in a rented lab.

Overview

  • The Investigative Committee confirmed two deaths and three injuries during hydrodynamic-stand testing at the university in Perm.
  • University information states a turbine wheel ruptured and its fragments pierced protective structures.
  • Officials corrected earlier conflicting reports that had cited four or five injured.
  • The deceased were identified as the head of the factory that produced the tested sample and his 8-year-old daughter.
  • Investigators said preliminary findings indicate the part did not withstand the load, and a criminal case for causing death by negligence is underway.
