Some of the most respected safety professionals I know have looked me in the eye and said, “I don’t know.” I respected them more for saying it, and that willingness is part of what safety professional credibility looks like.
There is a tendency in our profession to believe that experience, credentials, or a job title should come with an immediate answer. Someone asks a regulatory question, describes an unusual field condition, or wants to know whether a particular method is acceptable, and there can be pressure to respond on the spot.
That pressure can create problems.
A professional who feels compelled to answer immediately may reach for something remembered from a class years ago or apply a regulation before fully understanding the situation. Confidence can make an incomplete answer sound convincing.
I have come to believe that safety professional credibility depends just as much on recognizing the limits of our knowledge as it does on demonstrating what we know.
“I Don’t Know” Is the Beginning of the Work
There is a difference between admitting you do not know something and walking away from the responsibility to find out.
A strong safety professional can say:
“I don’t know. Let me look into it.”
That second sentence matters.
The responsibility remains. The professional is acknowledging that the information available is insufficient to give a reliable answer yet.
That may mean opening the applicable regulation and reading the actual language instead of relying on memory. It could also mean checking the manufacturer’s instructions or talking with someone who has deeper expertise in that operation.
There are situations where the answer needs to come from outside the safety department entirely.
Recognizing that strengthens professional judgment because the objective should be getting the answer right, not getting the answer first.
The People Doing the Work Know Things We Don’t
Construction should make safety professionals especially comfortable with admitting the limits of their knowledge.
I can walk onto a project with decades of construction and safety experience and still be standing beside someone who understands a particular operation better than I do.
An operator may have spent thousands of hours on a specific piece of equipment. A foreman may understand details about the work sequence that are impossible to see during a short site visit.
That knowledge matters.
The safety professional brings a different perspective. We should understand hazard recognition, regulatory requirements, risk management, and the systems that support safe work. That expertise has value, but a safety title does not automatically make someone the expert on every operation occurring on a project.
Sometimes the smartest thing I can say is:
“You know this operation better than I do. Walk me through what you’re doing.”
That conversation gives me information I did not have when I walked up.
It also communicates something important to the people performing the work. Their experience is part of the decision-making process.
This is one reason I have argued that construction safety professionals need to move beyond the role of the “safety cop.” Influence begins with understanding the work and the people responsible for performing it.
Expertise Includes Knowing When You Need Someone Else
One of the mistakes experience can create is the belief that we should eventually reach a point where we rarely need help.
My experience has taken me in the other direction.
The longer I work in construction, the more I recognize how many situations refuse to fit neatly into a classroom example. Equipment changes. Work methods evolve. Project conditions create circumstances that a written procedure may never have anticipated.
That is where judgment becomes important.
A structural issue may need engineering expertise. A question about a specific machine may need to go back to the manufacturer.
Knowing when to involve someone with deeper expertise is part of professional competence.
Experience should improve our ability to recognize when we have reached the edge of what we know.
Confidence and Certainty Are Different
People eventually figure out when someone is guessing.
They may not challenge an answer in the moment, particularly when the person giving it has authority or carries a safety title. They remember, however, when confident statements later turn out to be wrong.
Over time, that becomes a credibility problem.
If someone regularly speaks with certainty when the facts are unclear, people begin questioning the answers that person actually knows.
I have seen the opposite happen with professionals who are comfortable admitting uncertainty.
When someone has heard you say, “I don’t know, but I’ll find out,” it carries more weight when you return and say, “I checked it. Here is what I found.”
The credibility comes from the process.
The professional did not need to protect an image of knowing everything. Getting the answer right mattered more.
Judgment Matters in the Field
This connects directly to the relationship between safety professionals and supervision.
The superintendent or supervisor runs the work. They direct the crew and make decisions about how the work will be performed. A safety professional supports that process by identifying concerns, evaluating risk, and providing reliable information.
Walking onto a project and immediately telling experienced people how to perform their work before understanding the operation is a poor way to build trust.
There are times when a safety professional must speak up firmly, particularly when employees face serious hazards. Speaking up effectively still requires understanding the condition before deciding what should happen next.
A good safety professional may bring an observation to the supervisor and work through the issue with them. In another situation, the right contribution may be recognizing that additional information is needed before a sound decision can be made.
Construction regularly presents conditions that written policies cannot anticipate perfectly. I discussed that problem in When Safety Policies Reach Their Limits. The same principle applies here. Procedures matter, but eventually someone has to exercise judgment.
Knowing when you do not have enough information is part of that judgment.
The Answer Matters More Than Looking Like You Know
Safety professionals are expected to provide guidance. That expectation is reasonable.
People should be able to come to us when they need help understanding a hazard, interpreting a requirement, or finding the right resource.
That responsibility makes accuracy more important than speed.
An immediate answer has little value when it sends the crew in the wrong direction. Taking time to verify something before advising a supervisor or company can be the more professional response.
The best safety professionals I know have enough knowledge to contribute and enough experience to recognize where that knowledge ends.
When they do not know something, they say so.
Then they go find the answer.
Being willing to say “I don’t know” when the facts are incomplete is part of professional judgment.
