Hello,
The term "million man-hours" is a statistical measure used in safety management to calculate the frequency of accidents. This term is not specific to IS.3786, nor is it a statutory requirement.
The concept of a "million man-hours" comes from the industrial sector to calculate the accident frequency rate. The number "million" is chosen for practical reasons. Here's why:
1. 🚁 Standardization: Using 'million' man-hours is an internationally accepted standard that allows for easy comparison across industries, companies, and geographies.
2. 🚈 Ease of Measurement: Larger numbers such as 'million' help in creating a more comprehensive picture of safety performance over a longer period or across a larger workforce.
3. 🚥 Accuracy: Calculating accident rates over a larger scale like 'million' man-hours reduces the impact of smaller fluctuations and provides a more accurate reflection of safety performance.
4. 🚂 Statistical Significance: A larger scale like 'million' man-hours gives the value more statistical significance and reliability.
To calculate the accident frequency rate per million man-hours, you can follow these steps:
- Step 1: 🙆‍♂️ Collect the total number of reportable accidents in a given period.
- Step 2: 🚨 Determine the total man-hours worked in that same period.
- Step 3: 🕘 Calculate the accident frequency rate by dividing the total number of reportable accidents by total man-hours, and then multiply the result by 1,000,000.
Remember, the key here is to ensure accurate data collection and consistent calculation procedures to make the results meaningful and comparable.
