How Is Slip Risk Managed at Busy Transport Hubs?
Slip risk at busy transport hubs is managed by measuring the grip of the floor in the highest-risk zones, fixing what the measurements reveal, and maintaining the result with regular re-testing and records. Controls such as matting, cleaning and signage support this, but they do not replace it. The aim is to know how much grip a floor has when someone walks across it, rather than assuming it from how the floor looks.
The short why
A hub is too large, too busy and too varied to manage by instinct. Footfall never really stops, weather is carried in constantly, and flooring types change from one area to the next. Managing slip risk at that scale means putting measured evidence behind decisions, so effort goes where the risk actually sits.
Where does management start?
It starts with knowing which zones matter most. Not every square metre of a hub carries the same risk, and treating it all alike spreads effort thinly.
A useful way to think about it is by speed limits. Most of a building is a 70 mile an hour zone: dry, low-risk floor where the basics are enough. Some areas are 20 mile an hour zones, where floors are likely to get wet or contaminated and a higher standard of control is needed. In a hub, those are usually:
- Entrances and ticket halls, where outdoor weather meets indoor flooring
- Routes from platforms and taxi ranks
- Areas near food and drink outlets
- Toilets
- Transitions between surface types, such as ramps and stairs
Measurement and improvement should focus on those zones first.
Why isn’t looking clean a reliable test?
This is the belief worth challenging directly. A floor that looks clean is not necessarily a floor that is safe. Grip is invisible. A concourse can look spotless and dry and still have poor slip resistance, particularly where years of footfall have worn the surface smooth.
That is why hubs that manage risk well test to know, rather than judging by eye or by how long it has been since the last reported slip. Incident logs only record what has already gone wrong, and most slips and near misses are never reported, especially where passengers are in transit.
What are the practical controls, and where do they fall short?
Hubs typically use a mix of controls. Each has a place, and each has limits:
- Matting: dries feet before the main floor, but only works if it is large enough, made of effective material and well maintained. In our work, we have seen a major station with three metres of entrance matting where the floor was still wet well beyond it on a rainy day.
- Cleaning: removes contamination, but cleaning is an activity and a safe floor is an outcome. The wrong product can leave a residue that lowers grip, and no amount of cleaning restores a surface that has worn smooth.
- Signage: warns people that a hazard exists. It does not make the floor less slippery.
- Insurance: a safety net, not a safety strategy.
None of these tells you how much grip the floor has. That is the gap measurement fills.
How does the Slipology Method fit a hub?
The Slipology Method gives a repeatable structure that works across a whole estate.
Assess: measure the real risk with pendulum testing in the priority zones, wet and dry. A Pendulum Test Value (PTV) of 36 or above is generally regarded as low slip potential.
Amend: fix the floor and the conditions at source. That might be a treatment, a change to cleaning products or methods, or a review of matting.
Advocate: get buy-in from site teams and contractors so the right standards hold day to day.
Assure: maintain grip through the right cleaning approach and planned re-testing, because surfaces change under heavy footfall.
Affirm: prove the result with dated data.
Slip Safety Services has found that organisations following a measure, improve and prove approach see a 57%+ average reduction in slip incidents. The improvement comes from addressing real causes in the right places, rather than relying on a quiet incident log.
How do you keep standards consistent across a large estate?
Consistency matters as much as intensity. Use the same assessment method at every site, so results can be compared and patterns spotted across the portfolio. Apply the same zoning logic, with the most frequent testing in the highest-risk areas. Make sure contractors and cleaning teams work to the same standard, and keep dated records centrally rather than in separate site files.
This also protects you when contractors change or staff move on. The standard stays the same because it is written down and backed by data.
What to do about it
Identify your 20 mile an hour zones at each site: the entrances, wet routes, food outlets, toilets and transitions. Find out when each was last tested and whether the reading was taken wet as well as dry. Where there is no recent, dated reading, treat that as the first gap to close.
Then check the basics against what the measurements show. Is the matting long enough to cover where feet are wettest? Do the cleaning products suit each type of flooring? A professional slip test of your highest-risk zones will tell you whether each issue lies with matting, cleaning or the surface itself.

If you are not sure how consistently slip risk is being managed across your hubs, the Slip Prevention Scorecard takes a few minutes per site and gives you a clear starting point.
