Due Diligence

Regulatory Compliance and MLITSD Inspection Expectations

After a workplace accident, MLITSD inspectors immediately assess whether the employer conducted a competent and compliant investigation. Their focus is whether the employer followed correct investigative procedures under OHSA.

 

Inspectors routinely check for:

  • Proof that investigators (supervisors, managers, JHSC members) are formally trained to conduct incident investigations
  • A written accident investigation procedure, including scene control, evidence collection, and reporting steps
  • Documentation of corrective actions taken to prevent recurrence
  • Accurate root cause analysis, not just blaming worker error
  • Timely reporting of injuries, including compliance with OHSA Section 51/52/53
  • Supervisor competency, demonstrated through correct investigation handling
  • Consistency with Internal Responsibility System expectations

 

Completing this course helps organizations demonstrate due diligence following an incident, reduce enforcement risk, and meet the standards inspectors expect when reviewing an employer’s investigation process.
