Following an exhaustive investigation, authorities uncovered a series of critical safety lapses that directly contributed to the tragic trench collapse last year. The San Francisco District Attorney’s office found that the construction company failed to adhere to mandated OSHA regulations, particularly regarding proper trench shoring and hazard assessment protocols. Testimonies and site inspections revealed that supervisors routinely ignored warning signs and failed to implement essential protective measures, placing workers at significant risk.

Key violations cited in the investigation include:

  • Inadequate trench shielding and sloping
  • Lack of daily safety inspections and hazard evaluations
  • Ignoring employee safety concerns raised before the incident
  • Failure to provide proper safety training to on-site supervisors
