TRIR (Total Recordable Incident Rate) is an OSHA metric for measuring the safety of a company. This guide will explain how to calculate TRIR.
number of incidentsThe total number of OSHA recordable incidents in a given year.
number of hoursThe total number of hours worked by all employees within a given year.

What is TRIR?
TRIR stands for Total Recordable Incident Rate.
TRIR represents how often your employees are injured.
TRIR is typically in the range of 0-10 where lower is better. 3.1 is average. 0 is perfect.
Groups like OSHA, ISNet, or insurance providers use TRIR as a quick determination
of how safe your company is compared to others in your industry.
“Say your TRIR is 4. That means you have 4 injuries per 100 employees every year.”
How To Calculate TRIR
The formula for TRIR requires you to collect two numbers.
Incidents - the number of recordable incidents within a given year.
Hours - the number of hours worked in a given year.
Once you've gathered these numbers, the formula is easy.
Multiply Incidents * 200,000, then divide by Hours.
Or enter your numbers in the calculator above for an instant calculation along with
a comparison with industries averages.
Why 200,000? 200,000 is the total number of hours that 100 employees would work,
assuming 50 weeks at 40 hours-per-week.
Step 1) Count Incidents
Count the number of OSHA recordable incidents within the given year.

A work-related injury or illness must be recorded under the Occupational Safety and Health (OSH) Act if it results in one or more of the following:
Death.
Days away from work.
Restricted work or transfer to another job.
Medical treatment beyond first aid.
Loss of consciousness.
A significant injury or illness diagnosed by a physician or other licensed health care professional.
Step 2) Count Hours
Count the number of hours that your employees have worked within
the given year. For example, if you have 5 employees working 40 hours
per-week for 50 weeks, that's 5 * 40 * 50 = 1000 hours.
Step 3) Do The Math
Multiply Incidents * 200,000. Then divide by Hours.
TRIR typically comes out between 0-10.
What is a good TRIR?
The perfect TRIR is 0. Lower is always better.
Overall, 3.1 is the average TRIR across all industries in the United States.

A 'good' TRIR depends on your industry. For example, 2 may be good for
a construction company, but terrible for a call center.
This is because construction work is inherently dangerous but answering phone
calls is not. Keep in mind that TRIR is a blanket average of incident rates
but does not take into account severity or other factors. TRIR is typically
lower for smaller companies of 1-10 employees compared to larger companies.
The 2017 industry averages are listed below. Among those numbers, the highest
reported average is a TRIR of 10 for "Motor home manufacturing" and the lowest
reported average is a TRIR of 1 for "Air and gas compressor manufacturing".
Take a glance at the average TRIR rates by company size.
Mid-sized companies have the worst scores. Why?
With small companies, communication is easy. Information flows
with ease, new hires are carefully vetted, and it takes minimal
effort to ensure the team is following best practices.
As a company grows, communication breaks down. New hires
miss out on important information, turnover increases,
and information struggles to flow through the layers of
hierarchy and locations. Manual processes that used
to work are beginning to fail.
Eventually a company grows large enough that it couldn't possibly
function without streamlined processes. Automation is put in place,
and once again data flows to the
correct people, status reports automatically assign and track incomplete
tasks, information is archived for easy access, and new-hires are
on-boarded through carefully designed processes.
“Through immediate response times to issues and observations, and our focus on leading indicators, we have seen a 75% reduction in our TRIR.”
