Number of Days Lost given Severity Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Lost Days = Injury Severity Rate*Man Hour/1000
D_l = R_i*N_mh/1000
This formula uses 3 Variables

Variables Used

Lost Days - Lost Days defines the umber of days lost due to injury occurred.
Injury Severity Rate - Injury Severity Rate defines the number of days lost time due to injury for 1000 man hours worked.
Man Hour - Man Hour is used to measure the efforts needed to complete a task. 1 man hour is work completed in an hour of uninterrupted effort by an average worker.

STEP 1: Convert Input(s) to Base Unit

Injury Severity Rate: 18 --> No Conversion Required
Man Hour: 2500 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D_l = R_i*N_mh/1000 --> 18*2500/1000

Evaluating ... ...

D_l = 45

STEP 3: Convert Result to Output's Unit

45 --> No Conversion Required

FINAL ANSWER

45 <-- Lost Days
