Lost Time Incident Rate

The number of lost time incidents per 100 employees over a period of time

Every organization wants to create a safe and healthy work environment for its employees. However, accidents and incidents can happen even in the safest of workplaces. This is where Lost Time Incident Rate (LTIR) comes into the picture. LTIR measures the number of incidents that result in lost work time per 100 employees during a given period. It is a crucial metric for understanding the safety performance of an organization and identifying areas for improvement.

=== Lost Time Incident Rate: What It Is and Why It Matters===

Lost Time Incident Rate is one of the most commonly used safety performance metrics. It measures the number of incidents that result in lost work time per 100 employees. For instance, if an organization has five lost time incidents in a year, and it employs 200 people, then the LTIR would be 2.5 (5/200 x 100). The metric is calculated for a specific period, typically a year, and the lower the rate, the better the safety performance.

LTIR matters because it provides insight into the effectiveness of a company’s safety program. A high LTIR indicates that there are ongoing safety issues that need to be addressed. It can also mean increased costs associated with workers’ compensation, medical expenses, and lost productivity. A low LTIR, on the other hand, indicates that the organization has an effective safety program in place, which can lead to lower costs and higher productivity.

=== Turn LTIR into Actionable Insights: How to Improve Safety Performance===

To improve safety performance, organizations need to turn LTIR into actionable insights. Here are some steps that can help:

  1. Identify the root cause: Analyze the data to identify the root cause of the incidents. This will help in developing targeted interventions and solutions.
  2. Improve training: Ensure that employees receive adequate training on safety procedures, hazard recognition, and risk assessment.
  3. Enhance employee engagement: Encourage employees to participate in safety programs, identify hazards, and suggest solutions. This will increase their ownership of safety and help in creating a safety culture.
  4. Use technology: Leverage technology to automate safety processes, monitor safety performance, and identify potential hazards.
  5. Measure and monitor progress: Regularly measure and monitor LTIR to track progress and identify areas for improvement.
  6. Continuously improve: Safety is an ongoing process, and organizations need to continuously improve their safety programs and processes to achieve better results.


Lost Time Incident Rate is a crucial metric for organizations to assess their safety performance. By analyzing LTIR and turning it into actionable insights, organizations can identify areas for improvement, implement targeted interventions, and create a safer and healthier workplace. By continuously improving their safety programs and processes, organizations can achieve better safety outcomes, reduce costs, and enhance their productivity.
