Injury Rate Calculator

Calculate injury rates using total injuries and exposure time data

Input Parameters

Calculation Results

Calculation Formula

Injury Rate = (Total Injuries × 200,000) / (Worker Count × Exposure Time)

Where:
- Injury Rate: Injuries per 200,000 worker-hours
- Total Injuries: Number of work-related injuries
- Worker Count: Number of workers
- Exposure Time: Total hours worked by all workers

Injury Rate Calculator Usage Guide

Learn how to use the Injury Rate Calculator and understand its working principles

How to Use the Calculator

  1. Enter the total number of work-related injuries in the workplace during a specific period.
  2. Input the total exposure time (in hours) during the same period. This should include all worker hours.
  3. Specify the number of workers who were exposed to the risk during this period.
  4. Click the "Calculate" button to compute the injury rate.
  5. The calculator will display the injury rate per 200,000 worker-hours (a standard industry metric) and the injury rate per hour.

Understanding Injury Rate

The injury rate is a measure of workplace safety performance. A lower rate indicates better safety practices. The rate per 200,000 worker-hours is a standardized metric that allows for comparison across different companies and industries.

Example Calculation

Example: A company had 10 work-related injuries over a period where 50 workers worked a total of 100,000 hours.

Input:
Total Injuries: 10
Exposure Time: 100,000 hours
Worker Count: 50

Calculation:
Injury Rate = (10 × 200,000) / (50 × 100,000) = 20 per 200,000 worker-hours

Interpretation

This means that for every 200,000 hours worked by the company's workforce, there were 20 injuries. Companies compare their injury rates to industry benchmarks to assess their safety performance.
