OSHA quota
The OSHA incident rate (OSHA incident rate) is a method of calculating lost time due to occupational accidents .
This in the United States for work safety - statistics of OSHA method used is about 200,000 each incurred (real) labor hours are delivered. This is used to compare the frequency of accidents in the individual sectors and companies. There are different formulas to represent an OSHA accident rate. This calculation is also becoming more and more important in Germany due to globalization and standardization.
Probably the most important key figure is the so-called " accident frequency " (Lost Time Injury Rate - LTIR). It takes into account all accidents with fatalities (FAT) and downtime of 1 day or more (LTC)
Event frequency
The event frequency (Total Recordable Injury Rate, TRIR) is calculated from the number of registered accidents including fatalities (FAT), accidents with lost time (LTC), medical treatment (MTC) and reduced work capacity (RWC) per 200,000 hours worked:
Other key figures
- Lost Work Day Rate = (total number of absent days × 200,000) / number of hours actually worked.
- Severity rate = total number of days absent / total number of accidents at work = accident severity.
Germany
In Germany, the comparable 1000-man quota (TMQ) is used in the company accident statistics.
Formula: (number of reportable industrial accidents × 1000 employees) / number of full-time employees.
More precisely: number of notifiable industrial accidents × 1000 × number of average hours worked per employee and year (value is published annually by the employers' liability insurance association) / number of total hours worked in the year
