How to Calculate Your Company’s TRIR (Total Recordable Incident Rate)

When it comes to your company’s safety performance, another important acronym to learn is TRIR, which stands for “Total Recordable Incident Rate.” Below we’ll discuss what this metric is all about, and how your TRIR score can help improve your occupational health and safety efforts.

What is TRIR?

Total Recordable Incident Rate (TRIR) is a standardized safety metric used to calculate the number of work-related injuries and illnesses that occur within a company. It is also an essential metric organizations use to measure safety performance within their operations. It represents the number of recordable workplace incidents per 100,000 hours worked over a specified period.

This rate is calculated by taking the total number of recordable incidents, multiplying that by 100,000, and then dividing by the total number of hours worked. TRIR is a key component in understanding and improving workplace safety, as it provides a benchmark for comparing an organization’s safety record against industry standards or regulatory requirements. It is also a critical data point for identifying areas in need of safety improvements and for tracking the effectiveness of safety initiatives over time.

Why is TRIR Important to Calculate?

The Total Recordable Incident Rate (TRIR) is a vital metric for organizations to track as it quantifies safety performance within a workplace. It is calculated by taking the number of recordable incidents that occur in a workplace, multiplying it by 100,000, and dividing it by the total number of hours worked. This standardization allows for comparison across different industries or within an industry over time.

Calculating a company’s TRIR is important because:

Regulatory Compliance

Many industries are required by law to track and report TRIR to government agencies in the United States, such as OSHA. Non-compliance can result in penalties.

Safety Benchmarking

TRIR serves as a benchmark to compare an organization’s safety performance against industry averages or specific regulatory standards.

Performance Improvement

By understanding the frequency of incidents, organizations can identify patterns, implement safety initiatives, and measure the effectiveness of safety programs.

Risk Management

A high TRIR can indicate potential risks in the workplace, leading to increased insurance premiums or scrutiny from investors and stakeholders.

Company Reputation

Maintaining a low TRIR can enhance a company’s reputation as a safe place to work, which can be beneficial for recruiting talent and retaining employees.

Financial Impact

Workplace incidents can result in direct costs (such as medical expenses and compensation) and indirect costs (including lost productivity and potential legal fees), which can be substantial. Monitoring and reducing TRIR can, therefore, have a significant positive financial impact.

What are the Factors to be Considered When Calculating TRIR Scores?

The important factor to be considered while calculating the Total Recordable Incident Rate (TRIR) is the comprehensive and accurate documentation of all work-related injuries and illnesses that meet the Occupational Safety and Health Administration’s (OSHA) criteria for recordable incidents.

This includes any incident that results in death, loss of consciousness, days away from work, restricted work or transfer to another job, medical treatment beyond first aid, or a diagnosis of a significant injury or illness by a healthcare professional.

Additionally, the total employee hours worked during the period in question must be precisely recorded, as this figure is used as the denominator in the TRIR formula.

How to Calculate TRIR?

The Total Recordable Incident Rate (TRIR) is a metric used to evaluate the safety performance of a company by tracking the number of recordable work-related injuries and illnesses. To calculate TRIR, you would:

Total the number of OSHA recordable incidents for a given period.

Calculate the total number of hours worked by all employees during that period.

Apply the formula:

TRIR Formula

The multiplier of 200,000 represents the equivalent of 100 employees working full-time for a year (100 employees × 2,000 hours per year). This calculation provides a rate that can be compared across different industries and company sizes.

How Does TRIR Impact a Company’s Safety Performance?

The Total Recordable Incident Rate (TRIR) significantly impacts industries by providing a quantifiable measure of workplace safety. It affects various aspects of business operations, including:

Regulatory Compliance

Industries are often required to maintain certain safety standards, and TRIR is a key metric for regulatory bodies to assess compliance. High TRIR values may lead to increased scrutiny and potential fines.

Insurance and Liability

A lower TRIR can result in reduced insurance premiums as it indicates a safer work environment. Conversely, a high TRIR may increase insurance costs and liability exposure.

Investor Confidence

Investors often consider TRIR as part of their risk assessment. A low TRIR can attract investments by demonstrating effective risk management and a commitment to employee well-being.

Employee Morale and Retention

A safe workplace, as indicated by a low TRIR, can improve employee morale and retention rates. It shows that the company values its workforce and is committed to their safety.

Operational Costs

High TRIR values may indicate frequent incidents, leading to increased costs related to medical expenses, legal fees, and lost productivity.


TRIR can affect a company’s reputation. A reputation for safety can be a competitive advantage, while a poor safety record can damage a company’s public image and brand.

Continuous Improvement

TRIR serves as a benchmark for continuous improvement in safety practices. It helps industries to identify areas that need attention and to measure the impact of safety initiatives.

TRIR is more than just a number. It is a reflection of a company’s safety culture and operational efficiency. It has a broad impact on an industry’s financial health, regulatory standing, employee satisfaction, and overall reputation.

How to Reduce TRIR?

Reducing the Total Recordable Incident Rate (TRIR) involves a comprehensive approach to workplace safety that includes:

Implementing a Robust Safety Program

Establishing clear safety protocols, regular training, and education for employees.

Conducting Regular Safety Audits

Inspecting the workplace to identify and mitigate potential hazards.

Encouraging Reporting and Communication

Creating a culture where employees feel comfortable reporting safety concerns and near-misses.

Investing in Safety Equipment and PPE

Ensuring that all necessary safety equipment is available and maintained.

Analyzing Incidents and Near-Misses

Learning from past incidents to prevent future occurrences.

Employee Engagement

Involving employees in safety committees and discussions to promote a culture of safety.

Continuous Improvement

Regularly reviewing and updating safety practices to adapt to new challenges or changes in the workplace.

By focusing on these areas, organizations can work towards lowering their TRIR, which reflects a safer work environment and can lead to benefits such as lower insurance costs, improved employee morale, and a better company reputation.

In conclusion, the TRIR is a vital metric for assessing workplace safety and health performance. It provides a clear indication of how often recordable safety incidents occur and is a key component in benchmarking an organization’s safety initiatives against industry standards. By diligently tracking and aiming to reduce their TRIR, companies can not only ensure compliance with safety regulations but also foster a safer work environment, which can lead to improved employee morale, reduced costs associated with workplace incidents, and a more substantial reputation for corporate responsibility.
