I think by "lost time injuries" it's meant that the injuries that can occur will cause productivity and time on the job to be lost, because the person with the injury will need to take time off to heal.

A lost time injury (LTI) is an injury sustained by an employee that will ultimately lead to the loss of productive work time in the form of worker delays or absenteeism. You also may name it : A lost time accident But a non loss time injury will not ultimately lead to the loss of productive work time in the form of worker delays.

Hi! Can you explain the question a bit more clearly or in more detail?
