Confusion In Severity Rate - Pdf Download

Dear Hansa,

Please go through the below mentioned definitions hope it will clear you if not see the attached PDF which i had extracted from ''Process Safety'' document.

Severity Rate;

The severity rate is a calculation that gives a company an average of the number of lost days per recordable incident. Please note, that very few companies use the severity rate as a calculation, as it only provides an average. The calculation is made by dividing the total number of lost work days by the total number of recordable incidents.

Severity Index;

The severity index calculations include a category for “Community/Environmental” impact and a first aid (i.e.,OSHA “recordable injury”) level of Safety/Human Health impact which are not included in the PSI threshold criteria.However, the purpose of including both of these values is to achieve greater differentiation of severity points for incidents that result in any form or injury, community, or environmental impacts.

Hope its helps. . .

Team,

If i am wrong please educate me. . .

Thanks. . .
