Injury Frequency Rate given Injury Index Solution

Follow our step by step solution on how to calculate Injury Frequency Rate given Injury Index?

FIRST Step Consider the formula

I r = II \cdot \frac{1000}{I n \cdot R i}

Next Step Substitute values of Variables

∴

I r = 288 \cdot \frac{1000}{20 \cdot 18}

Next Step Prepare to Evaluate

∴

I r = 288 \cdot \frac{1000}{20 \cdot 18}

LAST Step Evaluate

∴

I r = 800

How to Evaluate Injury Frequency Rate given Injury Index?

Injury Frequency Rate given Injury Index evaluator uses Injury Frequency Rate = Injury Index*1000/(Number of Disabling Injuries*Injury Severity Rate) to evaluate the Injury Frequency Rate, The Injury Frequency Rate given Injury Index formula is defined as the number of disabling injuries per 1000000 man-hours worked. A disabling injury is one which causes loss of working time beyond the day or shift during which the injury occurred. Injury Frequency Rate is denoted by I_r symbol.

How to evaluate Injury Frequency Rate given Injury Index using this online evaluator? To use this online evaluator for Injury Frequency Rate given Injury Index, enter Injury Index (II), Number of Disabling Injuries (I_n) & Injury Severity Rate (R_i) and hit the calculate button.

FAQs on Injury Frequency Rate given Injury Index

What is the formula to find Injury Frequency Rate given Injury Index?

The formula of Injury Frequency Rate given Injury Index is expressed as Injury Frequency Rate = Injury Index*1000/(Number of Disabling Injuries*Injury Severity Rate). Here is an example- 800 = 288*1000/(20*18).

How to calculate Injury Frequency Rate given Injury Index?

With Injury Index (II), Number of Disabling Injuries (I_n) & Injury Severity Rate (R_i) we can find Injury Frequency Rate given Injury Index using the formula - Injury Frequency Rate = Injury Index*1000/(Number of Disabling Injuries*Injury Severity Rate).

What are the other ways to Calculate Injury Frequency Rate?

Here are the different ways to Calculate Injury Frequency Rate-

Injury Frequency Rate=Number of Disabling Injuries*100000/Man Hour
