Are industrial injuries and occupational diseases the same thing?

No. An industrial injury is typically a one-time event. For example, a fall, pop in your back, being struck by another driver while driving for work, or a sudden injury with a tool or machine.

An occupational disease is an injury that develops overtime, progressively. It is often referred to as a repetitive-type injury.  Examples include repetitive lifting or performing the same movements over-and-over again for prolonged periods of time (working on production lines, working on machinery, or repetitive manual labor).  The term “disease” can be misleading, as occupational disease claims can be the same physical injuries as industrial injury claims, and do not require having any association with contracting a disease.
