Lost Time Injury Frequency Rate

Measurement answer

What this metric measures

Reports lost time injury frequency rate as a governed SEBI BRSR Core result. The India applicability tier, standalone or value-chain population, denominator, method edition and reporting period remain explicit dimensions.

Specification

Metric specification

Result format
Single value
Unit
lost-time injuries per million person-hours worked - SEBI BRSR Core presentation
Reporting basis
The listed entity reporting period covered by its BRSR, with the financial year and any first-year comparative relief stated.
Aggregation
Aggregate only observations with the same entity or value-chain population, organizational boundary, period, unit, denominator, classification and BRSR Core method edition. Recompute ratios from compatible numerators and denominators instead of averaging reported percentages.

Reporting boundary

The SEBI-listed reporting entity boundary. A voluntarily reported value-chain observation retains upstream or downstream direction, partner population, attribution to the listed entity business, purchase or sales coverage, and aggregation basis; it is not merged into own operations.

Value structure

Dimensions and units

Unit
lost-time injuries per million person-hours worked - SEBI BRSR Core presentation
Reporting basis
The listed entity reporting period covered by its BRSR, with the financial year and any first-year comparative relief stated.

Unit meaning: Use lost-time injuries per million person-hours worked on the source-defined BRSR Core basis, retaining scale, currency, denominator and classification where applicable.

Published dimensions

  • BRSR Core attribute 5: Employee wellbeing and safety
  • Source parameter: Safety-related incidents for employees and workers
  • Reporting entity and financial year
  • Own operations or voluntarily reported attributable value-chain population
  • India market-capitalization applicability tier and assessment-or-assurance status
  • Unit, scale, denominator, classification and estimation basis
  • Current BRSR Core and ISF method edition

Rate

Formula

LTIFR = lost_time_injuries * 1,000,000 / person_hours_worked

Multiply qualifying lost-time injuries by one million and divide by total person-hours worked for the same employee and worker population and reporting period.

Evidence and status sources

Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Interpretation boundaries

Method disclosures required

Source-edition basis: BRSR Core Annexure 17A in the SEBI LODR Master Circular updated 30 January 2026, incorporating the 28 March 2025 amendments

  • State the BRSR Core edition, attribute, source parameter and reporting financial year.
  • State whether the observation covers own operations or a voluntarily reported attributable value-chain population.
  • State the unit, scale, denominator, classifications, source data, estimates and industry-specific adjustments.
  • State the applicable market-capitalization tier and whether assessment or assurance was obtained.

Record-specific limitations

  • The market-capitalization glide path determines regulatory applicability; it does not change the measured result.
  • Value-chain disclosure and associated assessment or assurance are voluntary under the current timetable and must remain separately labelled.
  • Annexure 17A is a base methodology and current ISF industry standards may require documented implementation adjustments.
  • Comparability depends on consistent boundary, source classifications, denominator, estimates and method edition.

Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.

Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
