Preventing slips mean controlling the grip of your floors, not just warning people about the risk. The most effective approach measures how slippery a floor actually is using specific pendulum testing, then improves the surface and maintenance routine to raise that grip permanently. Signs and mats manage the symptom. Measured, controlled grip removes the cause.
Signs are not a slip prevention plan
If you manage facilities across a hospitality estate, you already know the routine. A spill happens, a sign goes out, the floor gets mopped, and the incident log gets a note. It feels like due diligence. It looks like you have done your bit.
Here is the shift this article makes: a wet floor sign warn people about a hazard that already exists. It does not remove that hazard. Real slip prevention means controlling grip at the surface, so the floor is safer whether or not anyone remembered to put a sign out. That is the difference between managing a symptom and fixing a cause.
Why “It looks clean and dry” is not the same as safe
Grip is invisible. A floor can look spotless, feel dry underfoot, and still have a slip resistance low enough to cause a fall. Many facilities only find this out after an incident, because there has never been a reason to test the floor itself.
This matters especially in hospitality, where footfall is constant, floors change condition throughout the day, and the same surface might be safe at 9am and dangerous by 6pm once spills, polish build-up or steam from a kitchen have altered it. You cannot manage what you have not measured. Assuming a floor is safe because it looks fine is guesswork, not risk management.
What Actually drives Slip Risk in your Sites
Slip risk is rarely caused by one thing. It usually comes from several factors working together, and understanding them is the first step to controlling any of them. A useful way to break this down is to look at:
- Contamination: water, grease, food debris or dust sitting on the surface.
- Heel: the footwear staff and guests wear, and how it strikes the floor.
- Individual: behaviour, mobility and awareness of the person walking
- Maintenance: the cleaning methods, products and frequency used on site.
- Environment: Lighting, gradients, floor transitions and weather ingress at entrances.
- Surface: the floor material itself and its measured slip resistance.
A facilities manager cannot control every one of these on every site every day. But the surface and its maintenance are within your control, and they are usually where the biggest, most lasting improvement comes from.
How do you Actually Prevent Slips, Step-by-Step?
Preventing slips is a process, not a single fix. It works best when it follows a clear sequence rather than reacting to whatever the last incident happened to be.
- Assess; Measure the real risk with pendulum testing rather than a visual check. This gives you an objective number for how slippery a floor is, wet and dry.
- Amend; Fix the floor and the conditions causing the risk at source, whether that is the surface treatment, the cleaning product, or both.
- Advocate; Get buy-in from site teams and embed the right day-to-day behaviours around cleaning and reporting.
- Assure; Maintain the grip you have achieved with the right ongoing cleaning regime and periodic checks.
- Affirm; Prove the result with data, so you can show improvement rather than just claim it.
This sequence matters because it starts with measurement, not assumption. Once you know the actual slip resistance of a floor, every decision after that is based on evidence rather than guesswork.
Does Cleaning More Often Solve the Problem?
Not on its own, and sometimes it makes things worse. Cleaning removes dirt, but it does not necessarily remove risk. The wrong product or method can leave a residue that actually reduces grip, even on a floor that looks immaculate.
This is why the maintenance step in the process above comes after assessment and amendment, not instead of them. The right floor paired with the right care us what holds grip over time. Cleaning harder without knowing the floor’s baseline slip resistance is effort spent without evidence that it is working.
What Proof Looks Like
Facilities managers are used to being asked to justify spend, especially on something as unglamorous as flooring. The case for measured grip control is straightforward: prevention is an investment, not an expense. Incidents cost more than testing and treatment ever will, through injury, claims, downtime and reputational damage.
Slip Safety services has found an average reduction in slip incidents of 57% or more across more than 4,000 sites where floors were measured, treated and maintained through this process. That is not a promise for every site, but it shows what a measured, structured approach can achieve when it replaces guesswork.
What Good Looks Like
A site with grip properly under control looks quietly remarkable. Floors have a known, recorded slip resistance rating. Cleaning teams use products and methods matched to that surface, not whatever was used last. Standards are consistent across every site in the estate, not dependent on which manager happens to be on shift. Near misses are logged and reviewed rather than shrugged off. And when someone asks how safe your floors actually are, you have a number to answer with, not an opinion.
The New Belief
A safe floor needs control, not just a sign. Wet floor warnings and mats have their place, but they manage risk that already exists rather than removing it. Real slip prevention starts with measuring grip, improving it where it falls short, and proving the result with data. Stop guessing. Start measuring.

FAQ
What is the most effective way to prevent slips in a building? The most effective way is to measure the actual slip resistance of your floors using pendulum testing, then improve any surfaces that fall below a safe threshold. This addresses the cause of slip risk rather than only warning people about it, which is what signs and mats do.
Do wet floor signs actually prevent slips? Wet floor signs warn people about a hazard, but they do not remove it. A floor can remain just as slippery with a sign next to it. Genuine prevention comes from controlling the floor’s grip, not from warning about the risk after it exists.
How do I know if my floors are actually safe? You cannot reliably tell if a floor is safe just by looking at it or walking on it, because grip is invisible. The only way to know is to measure slip resistance with scientific testing, ideally in both wet and dry conditions.
How often should floors be tested for slip risk? This depends on footfall, floor type and how conditions change across the day, so there is no single fixed answer for every site. A slip risk assessment can help establish a sensible testing schedule based on your specific environment.
Is cleaning enough to prevent slips? Cleaning alone is not enough, because it removes dirt rather than measured slip risk. The wrong cleaning product or method can even reduce grip on some surfaces. Cleaning needs to be matched to the floor’s tested requirements as part of a wider prevention approach.
