Lost Time Injury

A warehouse worker is injured and cannot work the next scheduled day, so the incident may count as a lost time injury under the company's reporting rules. The team also needs to investigate the hazard and support the worker.

Define the threshold first: some organisations use days away from work after the day of injury, others use missed shifts under a contractual definition, and the chosen one must be recorded before any rate is reported. US OSHA recording criteria describe cases with days away from work and how to count them, but OSHA rules govern covered US employers and are not an automatic worldwide definition of an LTI.

OSHA also distinguishes days away from restricted work or job transfer, so a worker who returns with restrictions may be recorded differently from one who misses a day. Check work-relatedness as well, because an injury on company premises is not always recordable and one away from premises may be work-related, so apply governing criteria rather than simple location assumptions.

Count the incident once: the number of lost days measures severity or absence duration under the chosen method, but it is not the number of separate injuries. A frequency rate often divides LTIs by hours worked and multiplies by a convention such as one million, though some systems use 200,000 hours, so labels must show the base.

An illustrative LTIFR is LTIs x 1,000,000 divided by hours worked, so if two LTIs occur over 500,000 hours the rate is 4 per million hours, and you should confirm whose hours are included. Use comparable boundaries, since contractors, temporary workers and joint sites can be counted differently and a rate excluding high-risk contracted work is not comparable to one including it.

Track medical facts securely, so that a safety dashboard shows aggregate counts without exposing private diagnoses and case details go only to authorised roles. Do not celebrate zero uncritically either, because a period without recorded LTIs can reflect luck or underreporting, so ask whether hazards and near misses are being reported.

Avoid incentives to suppress claims, since a bonus tied only to zero LTIs may discourage workers from reporting injuries and prompt reporting and control improvements should be rewarded instead. Look at leading indicators such as hazard corrections, equipment checks, training quality and worker reports, which show prevention work before injuries occur, and investigate causes by finding the conditions and controls that failed, not only which worker made a mistake.

One event in a small team can swing the rate sharply, so use counts, hours and context alongside a rolling rate. Clarify return-to-work status by recording modified-duty cases under the chosen framework without pressuring an unsafe return, and make reporting timely so supervisors know how to report an incident and seek care without waiting for payroll absence records.

Review severity separately, compare external benchmarks cautiously because industries, reporting rules and workforce mix differ, and remember that local statutory reporting and insurance requirements apply independently of the KPI. Keep a clear audit trail, share lessons without unnecessary personal detail, measure corrective actions, and review after contractor changes, because outsourcing a risky task can make the internal rate fall while the hazard persists; for owners, an LTI count signals harm already suffered and should prompt better safety questions, not a declaration of success from a low number.
