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 1991 study showed that in confined spaces the relationship was significantly different: 1.2 minor injuries for each serious injury or death. [7] 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.

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 total recordable incident rate (TRIR) is a measure of occupational safety and health, useful for comparing working conditions in workplaces and industries.It is calculated by combining the actual number of safety incidents and total work hours of all employees with a standard employee group (100 employees working 40 hours a week for 50 weeks a year).
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]
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 ...
