Safety Formula || Loss Time Injury || Severity Rate || Frequency Rate || Accident Rate || LTI
Your Queries:
1)Lost Time Injury (LTI) Rate
**Formula:** (LTI x 1,000,000) / Total Man-Hours Worked
**Explanation:** Example: (5 x 1,000,000) / 2,000,000 = 2.5
Matlab: Har 10 lakh man-hours ke kaam par 2.5 logon ko aise chot lagi jo unko kaam par wapas aane se roki.
2) Severity Rate (SR) - Choton ki Gambhirta Ka Dar
**Formula:** (Total Lost Workdays x 1,000,000) / Total Man-Hours Worked
**Explanation:** Example: (100 x 1,000,000) / 2,000,000 = 50
Matlab: Har 10 lakh man-hours ke kaam par 50 din ka kaam injury ki wajah se khoya gaya.
3) Frequency Rate (FR) - Accident Kitni Baar Hua
**Formula:** (Total Reportable Cases x 1,000,000) / Total Man-Hours Worked
**Explanation:** Example: (10 x 1,000,000) / 2,000,000 = 5
Matlab: Har 10 lakh man-hours ke kaam par 5 reportable injuries hui.
4) Accident Rate (AR) - Har 1000 Logon Me Kitne Accidents
**Formula:** (Total Accidents x 1,000) / Average Number of Employees
**Explanation:**
Example: (20 x 1,000) / 500 =40
Matlab: Har 1000 employees par 40 accidents hote hain.
5) Near Miss Reporting Rate (NMRR) - Bach Gaye Wale Cases
**Formula:** (Total Near Misses x 1,000,000) / Total Man-Hours Worked
**Explanation:** Example: (50 x 1,000,000) / 2,000,000 = 25
Matlab: Har 10 lakh man-hours ke kaam par 25 baar aise cases hue jisme accident ho sakta tha, par bach gaye.
6) Safety Performance Index (SPI) - Kitna Safe Kaam Hua
**Formula:** (Total Safe Man-Hours / Total Work Hours) x 100
**Explanation:** Example: (1,900,000 / 2,000,000) x 100 = 95%
Matlab: 95% kaam bina kisi accident ke complete hua.
7) Total Recordable Incident Rate (TRIR) - Record Hone Wale Accidents
**Formula:** (Total Recordable Cases x 200,000) / Total Man-Hours Worked
**Explanation:** Example: (8 x 200,000) / 2,000,000 = 0.8
Matlab: Har 100 workers ke liye 0.8 accident record hua.
8) Fatal Accident Rate (FAR) - Kitni Death Hui
**Formula:** (Total Fatalities x 1,000,000) / Total Man-Hours Worked
**Explanation:** Example: (1 x 1,000,000) / 2,000,000 = 0.5
Matlab: Har 10 lakh man-hours ke kaam par 0.5 death hoti hai (yaani 2 million hours me ek death).
9) Safe Man-Hours - Accident Free Hours
**Formula:** Total Man-Hours - Lost Time Injury Hours
**Explanation:** Example: 2,000,000 - 10,000 = 1,990,000
Matlab: 1,990,000 ghante bina kisi lost-time injury ke kaam hua.
