Lost Time Injury Frequency Rate - LTIFR

Purpose

The Lost Time Injury Frequency Rate (LTIFR) measures the number of lost-time injuries per million hours worked. A lost-time injury is one that resulted in time lost from work of one day/shift or more. This includes injuries resulting in fatality or permanent disability

The hours worked are stored in the LTIFR module. These hours are then used to calculate frequency rates based on the count of specific incidents or impacts and then are used to display the frequency rates on CGR Dashboards and reports.

• Track Safety Metrics: LTIFR provides an accurate picture of workplace safety by tracking lost-time injuries over hours worked.
• Client Reporting: Enables detailed reporting for clients who require safety frequency metrics segmented by various classifications (e.g. staff vs contractors).
• Custom Scoping: Allows different injury types and project-based configurations for precise safety analytics.

Important Notes

• System Administrator access is required to configure LTIFR settings via admin panel.
• LTIFR relies on accurate work hour entries and appropriate mapping of incident data.
• Frequency rates are best calculated with consistent data input over a rolling time (e.g. 3 or 12 months).
• The csv importer can be used to upload backdated data.

Step-by-Step Guide to Setting Up LTIFR Configuration

1. Create a LTI Frequency Rate Configuration 

Navigate to Admin > LTI Frequency Rates.

Here, you define allowed projects and authorise users who can input hours worked.

And click on 'Save'.

2. Add LTI Frequency Rate Columns

Navigate to: Admin > LTI Frequency Rates Columns

Here, you define how data will be displayed in each LTI Frequency Rate row. Navigate to Admin > LTI Frequency Rates for adding the LTI Frequency Rate Columns.

Click 'Save' to add the column to your LTI Frequency Rate configuration.

Step-by-Step Guide To Recording Hours Worked For Frequency Rate Reporting

1.    Navigate to your name, click, and select LTI Frequency Rates

2.    Click the relevant LTI Frequency Rate Configuration.

If you want to create new LTI Frequency Rates – click on the '+Add' button on the top next to 'LTI Frequency Rates'.

Then Create an LTIFR Record for the Period and create a new record for the relevant period (e.g. June 2025) and click on 'Save'.

This acts as the container for storing hours and incident counts for that month.

3. Log Hours for Each Project and Column

Enter the hours worked for each project and classification column (e.g. 2000 hours under ‘Staff’, 500 under ‘Contractors’) and click on 'Save'.

Filters/Widgets related to LTIFR

[Optional] 
Create a Filter by Injured Person Type

This step is for clients who wish to separate frequency rates by the type of injured person (e.g. internal staff vs. external contractor).

Navigate to Admin > Filters and create a filter condition based on the injured person classification.

Once done, click on 'Save'.

This filter can then be applied to the LTI Frequency Rate columns.

[Optional] Create Filters for Injury Classification

There are many different Injury frequency rates metrics which change mainly based on the classification of the injury. The main one is Lost Time Injury (LTI) but depending on the client there can be many more. Here we create the filters for determining which incidents should be used for which frequency calculation.

Here, to distinguish between different frequency rate types (e.g. LTIs vs. Medical Treatments), create filters in Admin > Filters to define what qualifies as each injury type.

3.    Create Injury Types

Go to Admin > Injury Types to create each injury category and assign it the appropriate filter created in the above step. Once done, click on 'Save'.

4. Create the LTIFR widget to add to a Dashboard

Use the “LTIFR” widget type which handles all the logic for calculating the counts and frequency rates to support visualising the frequency rates on dashboards.

• Rolling Month Lag: Choose a rolling window (e.g. 3 or 12 months) for the frequency rate calculations. For example, the LTIFR value for December 2024 will include the LTIFR hours and incidents/impacts from Jan 2024 -> December 2024
• Columns: Choose injury classifications to display separate frequency rate series. (i.e.) Selecting the injured person classification will add extra frequency rate series for each of them.
• Injury Types: Select which injury types should be counted and plotted. Note that the counts series are not rolling. They just show the counts of matching incidents/impacts for the relevant month.

Understand Widget Behaviour

• The widget allows date range selections which are cached across the dashboard, further you can hide series by clicking on the legend and have it included in PDF exports.
• Click navigation is available for counts but not frequency rates.

Project scoping

LTIFR records (hours worked) and widgets are scoped by project. The hours worked are project scoped, so if there is a global filter on projects, it will filter out the hours worked, as well as the incidents. 

To scope a widget by default:

• Create filters on both Incidents and LTIFR Entries, and then,
• Apply these filters to the widget under its configuration.
