LTIFR (lost time injury frequency rate) is the number of lost time injuries occurring in a workplace per 1 million hours worked. An LTIFR of 7, for example, shows that 7 lost time injuries occur on a jobsite every 1 million hours worked. The formula gives a picture of how safe a workplace is for its workers.
A broad study of UK accident data in the mid-1990s showed a relationship of 1 fatality to 207 major injuries, to 1,402 injuries causing three or more days lost time injuries, to 2,754 minor injuries. [8] Heinrich's original files have since been lost so his accident figures cannot be proven. [2]
The total time taken for all waiting drivers to react and accelerate is the start-up lost time. Clearance lost time is the time lost to stopping a line of vehicles at the end of a green phase. Lost time is always measured in seconds. Start-up lost time can be calculated as the sum of the differences between the headways for the first cars in ...
Workers new to the job are at a much higher risk of injury than more experienced staff, while shift workers and part-time staff also have a greater risk of being injured at work. [39] The research shows that the amount of time employees worked was strongly linked to muscle and joint issues in the neck, lower back, left elbow, and right wrist. [41]
The time within which the death may occur varies among countries: in Netherlands an accident is registered as fatal if the victim dies during the same day that the accident happened, in Germany if death came within 30 days, while Belgium, France and Greece set no time limit. [6] Where the accidents involve multiple fatalities, they are often ...

There are factors for a near miss related to the operator, and factors related to the context. Fatigue is an example for the former. The risk of a car crash after a more than 24h shift for physicians has been observed to increase by 168%, and the risk of near miss by 460%. [4]
"Collateral damage" is a term for any incidental and undesired death, injury or other damage inflicted, especially on civilians, as the result of an activity. Originally coined to describe military operations, [ 1 ] it is now also used in non-military contexts to refer to negative unintended consequences of an action.
