where ILTC - number of lost time cases.
Using the previous company example, assume that one of the two recordable
cases had lost work days associated with the incident. The calculations would look
like this:

1 200 000
LTC Rate   , 5 41 .
37000

What is now known is that for every 100 employees, 5,41 employees have
suffered lost time because of a work related injury or illness.

3) Lost Work Day Rate (LWD Rate)
Lost Workday Rate – a mathematical calculation that describes the number of
lost work days per 100 full-time employees in any given time frame.
The Lost Work Day rate is primarily used only at larger companies. This does
not preclude a small business from using this calculation in their performance system,
however. The LWD Rate is calculated by multiplying the total number of lost work
days for the year by 200,000, then dividing that number by the number of employee
labor hours at the company.

where D - total number of lost days.

Using the previous company example and the broken-leg example used earlier,
there were 5 lost days due to the injury. The calculations would look like this:

5 200 000
LWD Rate   27 , 03 .
37000

What is now known is that for every 100 employees, 20,03 days were lost from
work due to work related injuries or illnesses.

4) Days Away/Restricted or Transfer Rate (DART Rate)
Days Away/Restricted or Job Transfer Rate – a mathematical calculation that
describes the number of recordable injuries and illnesses per 100 full-time employees
that resulted in days away from work, restricted work activity and/or job transfer that
a company has experienced in any given time frame.
The DART rate is relatively new to industry. This rate is calculated by adding
up the number of incidents that had one or more Lost Days, one or more Restricted
Days or that resulted in an employee transferring to a different job within the
company, and multiplying that number by 200,000, then dividing that number by the
number of employee labor hours at the company.
