Danger Slippery Surface Post Mount Signs give you a fixed warning for paths, yards, entrances, washdown routes and outdoor work areas where footing can quickly become unsafe. They help staff, contractors and visitors recognise slip hazards before stepping onto wet, oily or weather-affected ground.

Where Danger Slippery Surface Post Mount Signs Should Be Fitted

You should install these signs on posts, fencing or temporary barriers before people reach slippery ground, not after they are already walking across it. Use them around ramps, external paths, loading areas, wash bays, waste routes and entrances where water, oil, algae or cleaning residue can affect footing.

Viewing Distance Guidance for Safer Placement

For a 400 x 300 mm sign, position it where people can comfortably see and react from around 5–10 metres away in normal pedestrian areas. Use a shorter distance near tight corners or gateways, and add extra signs when vehicles, fencing or stored materials may block the warning.

Slip Risk Behaviour You Can Improve After Fitting

Once fitted in the right place, this sign helps people slow down, choose safer footing and take more care before crossing a known slippery surface. It is especially useful where the risk changes with rain, cleaning, spills or surface contamination.

✅ People receive the warning before entering the slippery section

✅ Staff can control repeat slip risks without relying on verbal reminders

✅ Visitors and contractors understand the hazard quickly from the W011 symbol

ⓘ Installation Guidance

Practical Fitting Advice for Slippery Surface Post Signs

❌ Placement errors that reduce warning value

❌ Fitting the sign after the slippery section has already started

❌ Mounting it too low behind bins, pallets or parked vehicles

❌ Using one sign where people approach from several directions

❌ Situations where this is not the best choice

❌ Not ideal as the only control for fresh spills needing immediate clean-up

❌ Not suitable where a temporary floor stand is needed directly on the hazard

❌ Not enough on its own if lighting or drainage problems remain unresolved

✅ Better fitting choices for lasting visibility

✅ Face the sign towards the approach route, not sideways to the hazard

✅ Tighten cable ties evenly through all four fixing holes

✅ Add repeat signs on long paths, blind corners or split pedestrian routes

? Customers Questions

Danger Slippery Surface Post Mount Signs questions answered

When should I choose a post mount slippery surface sign instead of a floor stand? Use this option when the hazard is repeated, outdoors, beside a route or in an area where a loose floor stand could be moved, knocked over or missed.

Is this sign suitable for wet outdoor areas? Yes. The 3mm polypropylene format is suitable for indoor or outdoor display, especially on fences, posts, barriers and routes exposed to rain or washdown water.

Does the sign message clearly explain the risk? Yes. The wording “Danger Slippery Surface” gives a direct warning, while the W011 slipping person symbol helps people understand the risk quickly.

Can this be used around yards, entrances and loading areas? Yes. It is well suited to yards, site entrances, ramps, loading routes, wash bays and external paths where surfaces can become slippery underfoot.

What should I check before fitting the sign? Check that the sign faces approaching pedestrians, sits at a readable height and is not hidden by parked vehicles, stock, fencing, vegetation or changing site layouts.

Where the warning needs to sit directly on a route, freestanding slippery surface floor warnings can be positioned close to the immediate risk. Useful for wet floors, spills and cleaning tasks.

For temporary outdoor control, moveable slippery surface post signs help you warn people without committing to a permanent fixing. A practical choice for changing access routes.

If you need a more formal entrance warning, stanchion mounted slippery surface signs can support clearer visibility in public-facing areas. Helpful for reception areas, walkways and managed access points.
