Walk into any heavy manufacturing plant in the Midwest or a distribution center outside of Phoenix and you’ll see it. It’s usually propped up near the time clock or bolted to the main gate. A big, often digital, display screaming a number in bright red or green LEDs. We’re talking about the days since last accident sign. It’s a staple of industrial life, as common as hard hats and steel-toed boots. But honestly, have you ever stopped to wonder if that ticking number actually keeps anyone safer, or if it's just a psychological pressure cooker?
Safety culture is a weird beast. You can’t just buy "safety" off a shelf. You have to build it. For decades, managers have leaned on these signs as a visual shorthand for "we care." It’s a scoreboard. Humans love scoreboards. We like seeing the number go up. It feels like winning. But there’s a dark side to that digital tally that most safety consultants are finally starting to whisper about in boardrooms.
The Psychology of the Ticking Clock
The fundamental goal of a days since last accident sign is transparency. It’s supposed to foster a sense of collective responsibility. When the number hits 365, there’s usually a pizza party or a bonus check involved. People feel proud. They've looked out for each other. But here’s where things get kinda messy.
When a team is at 364 days and someone gets a deep gash on their forearm that probably needs three stitches, what do you think happens? In a perfect world, they go to the foreman, get medical help, and the sign resets to zero. In the real world? There is massive, crushing peer pressure to "tough it out." Nobody wants to be the person who killed the pizza party. This is what safety experts call "under-reporting," and it is the silent killer of actual workplace health.
If your sign is the only way you measure success, you aren't measuring safety. You're measuring silence.
Why OSHA Has a Complicated Relationship with the Scoreboard
The Occupational Safety and Health Administration (OSHA) doesn't explicitly ban the days since last accident sign, but they’ve certainly cast a side-eye at them over the years. In 2012, and again in more recent clarifications regarding VPP (Voluntary Protection Programs), OSHA made it clear that incentive programs shouldn't discourage reporting.
If a company says, "Everyone gets a $500 bonus if the sign hits 100 days," and then a worker gets hurt, that worker is now financially incentivized to lie. That’s a huge red flag. It creates a culture where hazards are swept under the rug until they explode into something much worse. You’ve probably seen it yourself—the guy who wraps a rag around a bleeding finger and keeps working because he doesn't want to let the "team" down. It’s noble in a movie, but it's a liability nightmare in a warehouse.
Modern Variations of the Days Since Last Accident Sign
Not all signs are created equal. The old-school ones were basically dry-erase boards where the night shift lead would forget to update the date for three weeks. Those were useless. Now, we have smart signs.
- Digital LED Displays: These are the most common. They sync with the company’s internal reporting software. If an incident is logged, the sign resets automatically. It’s objective.
- Multi-Metric Boards: Instead of just "days since," these might show "Total Safe Hours" or "Days Without a Lost-Time Injury." There’s a distinction there. A "recordable" injury might not stop the clock, but a "lost-time" injury (where someone can’t come to work) will.
- The "Safety Awareness" Approach: These signs ditch the number entirely and focus on "Current Safety Goal: Zero Trips."
One specific company, Electronic Displays Inc., has seen a shift in how these are ordered. It's not just about the number anymore. It's about the messaging. You'll see boards now that include scrolling tickers with safety tips or weather alerts. It turns the sign from a "shame board" into a communication hub.
The Problem with "Zero Harm" Rhetoric
For a long time, the holy grail was "Zero." Zero accidents. Zero injuries. It sounds great on a brochure. But experts like Dr. Todd Conklin, a Senior Advisor for Organizational and Safety Culture at Los Alamos National Laboratory, argue that "Zero" is a dangerous goal.

Why? Because accidents are often the result of complex system failures, not just a person being "careless." If you fixate on the days since last accident sign hitting a certain number, you're focusing on the outcome rather than the process. You can be lucky for 100 days, but that doesn't mean you're safe. It just means nothing has gone wrong yet.
True safety isn't the absence of accidents. It's the presence of capacity. It’s having the right guards on the machines, the right training for the forklift drivers, and a culture where a 20-year veteran feels comfortable telling the CEO, "Hey, this rack looks unstable."
Is it Time to Ditch Your Sign?
Maybe. But probably not.
Most workers actually like the sign. It’s a landmark. It’s part of the furniture. If you rip it down tomorrow, people might think management has stopped caring about safety altogether. The trick is to change what the sign represents.
Think about the difference between a "Days Since" sign and a "Days of Continuous Improvement" sign. One is a countdown to failure; the other is a record of effort.
Some sites have moved to tracking "Leading Indicators." This is a huge trend in EHS (Environment, Health, and Safety) circles. Instead of counting how many people didn't get hurt, they count how many safety audits were completed. They count how many "Near Misses" were reported.
Wait, reporting a "Near Miss" is a good thing? Absolutely.
A near miss is a free lesson. If a pallet falls and hits nobody, that's a gift from the universe. If you report it, you can fix the shelf. If you hide it because you're scared of resetting the days since last accident sign, that pallet is going to hit someone next week.
Implementing a Better Visual Safety Strategy
If you're going to use a sign, do it right. Don't make it the centerpiece of your safety program. It’s a supplement, not the main course.
First, look at the location. If it's only in the breakroom, it's just background noise. If it's at the entrance, it sets the tone for the shift. But don't put it in a spot where it feels like a looming threat.
Second, be transparent about what "accident" means. Does a bee sting count? Does a minor scrape that needs a Band-Aid count? If the rules aren't clear, the "score" feels arbitrary. Most successful plants use the OSHA Recordable definition. It’s a standard everyone can look up.
Third, celebrate the milestones, but don't tie them to big cash. When the days since last accident sign hits a big number, do something communal. A catered lunch. New high-quality gloves for everyone. Something that reinforces the tools of safety, not just the avoidance of a reset.
Real-World Examples: When the Sign Works
Take a look at companies that have high-risk environments, like ExxonMobil or GE. They use these displays, but they’re integrated into a massive system called a Safety Management System (SMS). For them, the sign is just a data point.
I remember talking to a site manager at a chemical plant in Ohio. They had a digital sign that had been running for over 1,000 days. He was terrified of it. He knew that the longer that number grew, the more likely his crew was to hide a small mistake. So, he did something radical. He manually reset the sign and threw a party anyway. He told the crew, "We've been lucky and good, but let's start fresh so the pressure is off."
That’s leadership. He recognized that the days since last accident sign had become a burden rather than a badge of honor.
Actionable Steps for Improving Workplace Safety Visibility
- Audit your current reporting culture. Ask your workers anonymously: "If you had a minor injury, would you report it if it meant the sign went to zero?" If the answer is no, your sign is lying to you.
- Focus on Leading Indicators. Start tracking things like "Safety Suggestions Submitted" or "Hazardous Conditions Fixed." Display those numbers alongside your "Days Since" tally. It shows that safety is an active job, not a passive state.
- Modernize the hardware. If you're still using a chalkboard, get a digital display. Not for the "cool factor," but because you can use it to display more than just one number. Use it to show the names of the safety committee members or the "Tool of the Month."
- Redefine the "Reset." Make sure your team knows that resetting the sign isn't a failure—it's a moment of honesty. The person who reports the accident that resets the clock should be treated with respect, not resentment. They just saved the next person from the same fate.
- Avoid "The Bonus Trap." Never, ever tie significant financial incentives directly to the number on that sign. It’s the fastest way to corrupt your data and put your workers at risk.
The days since last accident sign isn't going anywhere. It’s a part of industrial DNA. But as we move toward a more sophisticated understanding of human factors and organizational psychology, the way we use these signs has to evolve. It shouldn't be a sword hanging over the employees' heads. It should be a reflection of a workplace where people are empowered to speak up, stay safe, and—most importantly—go home in the same condition they arrived.
Safety isn't about the number on the wall. It's about the culture on the floor. If the sign helps you get there, great. If it stands in the way, it's just a piece of scrap metal.
