Severity Rate given Injury Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Injury Severity Rate = Injury Index*1000/(Number of Disabling Injuries*Injury Frequency Rate)
R_i = II*1000/(I_n*I_r)
This formula uses 4 Variables

Variables Used

Injury Severity Rate - Injury Severity Rate defines the number of days lost time due to injury for 1000 man hours worked.
Injury Index - Injury Index gives the overall picture of injuries signifying both frequency and severity.
Number of Disabling Injuries - Number of Disabling Injuries refers to the injuries that result in either death or permanent disability, or temporary total disability after the day of injury.
Injury Frequency Rate - Injury Frequency Rate defines the number of disabling injuries per one lakh man hours worked.

STEP 1: Convert Input(s) to Base Unit

Injury Index: 288 --> No Conversion Required
Number of Disabling Injuries: 20 --> No Conversion Required
Injury Frequency Rate: 800 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_i = II*1000/(I_n*I_r) --> 288*1000/(20*800)

Evaluating ... ...

R_i = 18

STEP 3: Convert Result to Output's Unit

18 --> No Conversion Required

FINAL ANSWER

18 <-- Injury Severity Rate

Number of Disabling Injuries given Frequency Rate

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

Number of Man-Hour Worked given Frequency Rate

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

Injury Frequency Rate

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

Injury Severity Rate

LaTeX Go Injury Severity Rate = Lost Days*1000/Man Hour

Severity Rate given Injury Index Formula

LaTeX Go

Injury Severity Rate = Injury Index*1000/(Number of Disabling Injuries*Injury Frequency Rate)
R_i = II*1000/(I_n*I_r)

What are the Approaches to Improve Safety in Construction Field?

1 Organizational approach
i. Safety departments
ii. Committee
iii. Field Procedures
iv. Incentives
v. Safety Cost
2 Physical Approach
3 Economic incentives
4 Behavioral Approach

What is Disabling Injury?

The disabling injury means an injury which causes a loss of working time beyond the term, shift or day during which the injury occurred. Thus injury-frequency rate denotes how frequently accidents occurred. Bat it does not take into account the time lost because of an injury.

How to Calculate Severity Rate given Injury Index?

Severity Rate given Injury Index calculator uses Injury Severity Rate = Injury Index*1000/(Number of Disabling Injuries*Injury Frequency Rate) to calculate the Injury Severity Rate, The Severity Rate given Injury Index formula is defined as the number of days lost because of injuries per 1000 man hours worked. Injury Severity Rate is denoted by R_i symbol.

How to calculate Severity Rate given Injury Index using this online calculator? To use this online calculator for Severity Rate given Injury Index, enter Injury Index (II), Number of Disabling Injuries (I_n) & Injury Frequency Rate (I_r) and hit the calculate button. Here is how the Severity Rate given Injury Index calculation can be explained with given input values -> 18 = 288*1000/(20*800).

FAQ

What is Severity Rate given Injury Index?

The Severity Rate given Injury Index formula is defined as the number of days lost because of injuries per 1000 man hours worked and is represented as R_i = II*1000/(I_n*I_r) or Injury Severity Rate = Injury Index*1000/(Number of Disabling Injuries*Injury Frequency Rate). Injury Index gives the overall picture of injuries signifying both frequency and severity, Number of Disabling Injuries refers to the injuries that result in either death or permanent disability, or temporary total disability after the day of injury & Injury Frequency Rate defines the number of disabling injuries per one lakh man hours worked.

How to calculate Severity Rate given Injury Index?

The Severity Rate given Injury Index formula is defined as the number of days lost because of injuries per 1000 man hours worked is calculated using Injury Severity Rate = Injury Index*1000/(Number of Disabling Injuries*Injury Frequency Rate). To calculate Severity Rate given Injury Index, you need Injury Index (II), Number of Disabling Injuries (I_n) & Injury Frequency Rate (I_r). With our tool, you need to enter the respective value for Injury Index, Number of Disabling Injuries & Injury Frequency Rate and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Injury Severity Rate?

In this formula, Injury Severity Rate uses Injury Index, Number of Disabling Injuries & Injury Frequency Rate. We can use 1 other way(s) to calculate the same, which is/are as follows -

Injury Severity Rate = Lost Days*1000/Man Hour
