Safety Performance Indicators,Accident Calculations, LTI, LTIFR, TIFR, SR


Fatal Accident / Injury

A death resulting from an occupational injury or disease/illness and identified within the reporting period.

Serious Accident / Injury

Any injury which results in permanent loss of any part or section of a body or the use of any part or section of a body, or the permanent loss of or injury to the sight or hearing or any permanent physical incapacity or the fracture of any bone or one or more joints or bones of any phalanges of hand or foot.

Reportable Accident

Any accident / injury which causes a loss of time for more than 48 hours as per The Factories Act 1948 or more than 72 hours as per The Mines Act 1956.

Non-Reportable Accident

Any accident / injury which causes a loss of time ranging from 24 to 48 hours as per The Factories Act 1948 or 2 to 72 hours as per The Mines Act 1956.

First-aid injury

An injury, which requires medical treatment only and does not have any loss time extending beyond the day or shift during which the accident occurred.

Loss Time Injuries (LTI)

An injury / accident forcing the employee to remain away from his / her work beyond the day of accident.

Man-Hours Worked
                                            
Total man-hours worked during the month calculated as man-days physically present at workplace multiplied by 8 (8=Working hours per day).

Man-Hours lost

These are total man-hours lost during the month due to loss time injuries / accidents calculated as man-days lost multiplied by 8 (8=Working hours per day).


Calculations

Loss Time Injury Frequency Rate (LTIFR)

The number of lost time injuries (LTI)* per one million hours worked.

     Number of loss time injuries(Dept+Contractors)
LTIFR = ----------------------------------------------------------------x 1000,000
                        Man-Hours worked (Dept + contractor)

Total Injury Frequency Rate (TIFR)

The number of total injuries per one million hours worked

               Total number of injuries*(Dept+Contractors)
TIFR =  -----------------------------------------------------------    X 1000,000
                  Man-Hours worked (Dept + contractor)

* Total Injuries = Loss Time Injuries + First Aid Injuries


Severity Rate (SR)

The total number of man-days lost per 1000 days worked.

                          Man-days lost(Dept+contractors)
        SR =     ----------------------------------------------------  X 1000
                      Man-days worked (Dept + contractor)

The number of man-days lost for a Fatal accident shall be taken as 6000.
