Safety measurement is a big and important topic in occupational safety and health. We went into this issue in detail in a recorded discussion with Pam Walaski called Safety Metrics Reconsidered, we also discussed it during parts of recorded discussions with Ron Gantt (Safety Classics Reconsidered) and Carsten Busch (10 Common Safety Myths), and we plan on talking with Carsten Busch again soon on the topic, as he's published a new book addressing issues around safety measurement (stay tuned for that).
In addition, the NSC/Campbell Library has done a lot of good research and publishing on the topic (we'll cover that in an upcoming blog post) and OSHA published a document titled Using Leading Indicators to Improve Safety and Health Outcomes in June of 2019. It's that newish OSHA document on using leading indicators for safety measurement and safety improvement we're going to focus on in this article.
Of course, we recommend you read the entire OSHA document on leading indicators and how to use them to improve your occupational safety and health program, but here are a few items that caught our eye. All quotes below are from OSHA's Leading Indicators document.
So what is a leading indicator, you ask, and in particular a leading indicator as applied to occupational safety and health? Here's how OSHA explains it:
For purposes of this document, leading indicators are proactive, preventive, and predictive measures that provide information about the effective performance of your safety and health activities. They measure events leading up to injuries, illnesses, and other incidents and reveal potential problems in your safety and health program.
Now that you know what a leading indicator is, you may be wondering what a lagging indicator is (and, again, want to hear OSHA's take on using lagging indicators in occupational safety and health). Here's how OSHA explains lagging indicators:
In contrast, lagging indicators measure the occurrence and frequency of events that occurred in the past, such as the number or rate of injuries, illnesses, and fatalities.
Sometimes safety professionals who are eager to begin using leading indicators talk dismiss lagging indicators entirely. But this risks throwing the baby out with the bathwater, and it isn't OSHA's recommendation.
Here's how OSHA suggests using leading and lagging indicators together for evaluating the effectiveness of your safety management program at work.
While lagging indicators can alert you to a failure in an area of your safety and health program or to the existence of a hazard, leading indicators allow you to take preventive action to address that failure or hazard before it turns into an incident. A good program uses leading indicators to drive change and lagging indicators to measure effectiveness.
So while it's TRUE that safety professionals have relied too strongly on lagging indicators (incident rates, DART, TRIR, etc.) in the past, that doesn't mean we shouldn't use them now. At least not according to OSHA, which might mean quite a bit to US employers.
Great. Now we know what a leading indicator is. But why should we use them?
Here are a few benefits that OSHA suggests employers will see by adopting leading indicators in their safety management program:
OSHA's document says that leading indicators must be SMART, meaning they're:
Read pages 2 & 3 of OSHA's document for more on this.
So if you've now bought into the idea of using leading indicators for safety management, you may want a paint-by-the-numbers playbook you can follow step-by-step to get started.
But, alas, it's not that easy. As OSHA explains, "there is no 'one size fits all' way to use leading indicators."
You'll need to select and use leading indicators in ways that are appropriate for your organization. Here's how OSHA explains it:
Employers with newer programs may use indicators that focus on starting a program, while employers with more mature programs may use them to monitor how close they are to achieving higher performance targets. Some employers may also find it helpful to limit the number of leading indicators they start out with or how many they use at any one time. How employers assign who will track and carry out goals for leading indicators can vary based on the size of the business, who the business has on staff, whether the business has a safety manager, and the scope of job duties of the employers’ workforce.
OSHA does list (and thoroughly explain, with helpful examples) three different ways organizations may use leading indicators.
These three ways are:
See pages 4-16 for a LOT more information and examples on these three general approaches to using leading indicators for safety improvements.
On page 4, in explaining a process for using leading indicators, OSHA outlines a process within the familiar Plan-Do-Check-Act cycle for continuous improvement. In the "Plan" stage, they suggest "choosing a leading indicator" and "setting a goal." In the "Do" stage, they list "Communicate" and "Start Using Your Indicators." In the "Check" phase, they suggest "Periodically Rechecking Your Goal and Indicators." And in the "Act" phase, they say you should "Respond to What You've Learned."

The OSHA document Recommended Practices for Safety and Health Programs lists 7 core elements of a safety and health management program. They are:
OSHA's document on using leading indicators for safety improvements notes:
Leading indicators can help you improve on these core elements of your safety and health program. Tying elements of a safety and health program directly to lagging indicators such as injury rates may be difficult, but experience shows that better programs do improve safety.

OSHA concludes its document on using leading indicators by providing the following "action plan checklist" items for you:
Identify your top problem areas--start with hazards, and with hazards with the greatest likelihood of harming workers based on severity/frequency (see our articles What Is Risk? and Risk Management and Safety and download our free guide to risk-based safety management).
