Walk into any mall, restaurant, or hotel lobby and you’ll eventually see it. It’s usually a yellow plastic A-frame or a draped piece of fabric over a parking meter. Maybe it’s just a piece of printer paper taped to a restroom door with a frantic "Sign Not in Use" scrawled in Sharpie. Most people ignore them. You probably do too. But honestly, if you’re a business owner or a facility manager, that little sign is often the only thing standing between you and a massive personal injury lawsuit that could bankrupt your operation.
It's weird. We live in a world where we expect everything to work all the time. When a piece of infrastructure fails, our first instinct is frustration. But legally speaking, that sign is doing a lot of heavy lifting. It's not just a "broken" indicator; it's a legal instrument of notice.
Why a Sign Not in Use is a Legal Shield
Premises liability is a nightmare. In most jurisdictions, if you invite the public onto your property, you owe them a "duty of care." This means you have to keep the place reasonably safe. When a piece of equipment—like an escalator, an ATM, or even a simple hand sanitizer station—breaks down, it becomes a hazard. If someone tries to use a broken escalator and falls, they’re going to sue.
But here is the kicker: the moment you put up a sign not in use, you’ve fundamentally changed the legal landscape. You have provided "constructive notice." You told the world, "Hey, this thing is broken, don't touch it." If they touch it anyway? That’s often on them.
According to the National Floor Safety Institute (NFSI), slip and fall accidents account for over 8 million hospital emergency room visits annually. A significant portion of these occur because a hazard wasn't properly marked. A sign not in use isn't just about functionality; it's about defining the boundaries of safe behavior in a commercial space.
The Psychology of Ignoring the Obvious
People are predictably irrational. We see a sign that says a fountain is out of order, and we still try to press the button. Why? Psychologists call this "habituation." We are so used to seeing signs in our environment that we often tune them out. This is why the design of a sign not in use actually matters more than the words on it.
Contrast is king. If you use a white sign on a white wall, you’re asking for trouble. This is why OSHA (the Occupational Safety and Health Administration) has such strict rules about safety colors. Yellow means caution. Red means danger. If you’re using a "sign not in use" because a piece of heavy machinery is down, and you just use a post-it note, a court is going to find that "inadequate."

I’ve seen cases where businesses were held liable despite having a sign. Why? Because the sign was too small. Or it fell over. Or it was written in a language the local population doesn't speak. You've got to be smart about it.
When "Not in Use" Becomes an Eyesore
There is a flip side to this. We've all seen that one "out of order" sign at the local park that looks like it’s been there since 1994. It’s faded, peeling, and covered in grime. This creates a "Broken Windows" effect for businesses.
When a sign not in use stays up for too long, it sends a message of neglect. It tells your customers that you don’t care about your infrastructure. For a brand, that’s poison. If you can’t fix a vending machine in three months, what does that say about your quality control elsewhere?
Think about the hospitality industry. A luxury hotel cannot afford to have a "Sign Not in Use" on a treadmill in the gym for more than 24 hours. It ruins the aesthetic. It breaks the illusion of perfection. In these high-stakes environments, the sign itself is often custom-branded to look intentional, rather than like a failure.
The Difference Between Out of Order and Not in Use
Words matter. "Out of Order" implies a mechanical failure that needs fixing. "Not in Use" can be a strategic choice. During the height of the 2020-2022 period, we saw "Not in Use" signs on every other table in restaurants. This wasn't because the tables were broken. It was for social distancing.
This distinction is important for asset management.

- Out of Order: Reactive. Something broke. Fix it.
- Not in Use: Proactive or Operational. We are choosing not to use this.
If you’re a facility manager, you need to be clear about which one you’re using. If you mark a bridge as "not in use" but it's actually "structurally unsound," and someone walks on it thinking it's just closed for cleaning, you’re in hot water. Clarity is your best friend.
How to Deploy a Sign Not in Use Properly
Don't just slap a sign on something and walk away. There is a right way to do this that protects your business and keeps people safe.
First, make it visible. The sign should be at eye level. If it's for a floor hazard, it needs to be tall enough that someone looking at their phone (which is everyone) will see it in their peripheral vision.
Second, be specific. Instead of just saying "Not in Use," maybe say "Closed for Maintenance" or "Do Not Enter - Floor Wet." The more information you give, the less likely someone is to ignore it.
Third, secure it. A sign that blows away in the wind or gets knocked over by a kid is useless. Use weighted bases for A-frames. Use industrial-strength adhesive for door signs.
Real World Consequences: The Case of the Missing Warning
There was a famous case involving a major retail chain where a customer slipped on a freshly mopped floor. The janitor had placed a "Sign Not in Use" near the janitorial closet, but not near the actual wet spot. The court ruled that the sign was "insufficiently proximate" to the hazard.

Basically, the sign existed, but it was useless because it wasn't where the danger was. You can't just have one sign for the whole building. You need to "tether" the sign to the specific asset that is out of commission.
The Future of the Warning Sign
We're moving toward digital signage. In smart buildings, you might not see a plastic sign at all. Instead, your phone might buzz when you get near a broken elevator, or the floor itself might light up with a red LED border.
But honestly? I think the physical sign not in use is here to stay. There is something visceral about a physical barrier. It’s a primitive "stop" signal that our brains process faster than a notification on a smartwatch.
If you are managing a property, treat these signs as part of your "Safety Stack." They are just as important as your fire extinguishers or your security cameras.
Actionable Steps for Business Owners
Stop treating signage as an afterthought. It's a core component of your risk management strategy.
- Audit your "out of order" inventory. Do you actually have professional, high-visibility signs, or are you relying on your employees to find a piece of cardboard and a pen? Buy a set of heavy-duty, OSHA-compliant A-frames today.
- Establish a "Sign Longevity" rule. If a sign not in use has been up for more than 72 hours, it needs to be escalated to a senior manager. Why isn't the repair happening?
- Check placement daily. Make it part of the morning walkthrough. Is the sign still there? Is it visible from all points of entry?
- Update the language. If you’re closing something for a specific reason (like a renovation), say so. "Improving this space for you" sounds a lot better than "Not in Use."
At the end of the day, a sign is a communication tool. Use it to protect your customers, but also use it to protect your bottom line. A little bit of yellow plastic is a lot cheaper than a settlement.
