Slips, Trips and Falls — Cutting the Most Common Site Injuries (2026)

Why It Matters

Same-level slips, trips and falls are consistently the most common cause of major and non-fatal injuries reported in Great Britain. They are also one of the biggest sources of lost-time accidents on construction sites — the kind of injury that takes someone off the tools for days or weeks, costs you a worker, and can drag your insurance premiums up with it.

The danger is not just the fall itself. A slip or trip that happens near an unprotected edge, a floor opening, a ladder or scaffold can turn into a fall from height — which is how the most common minor incident becomes one of the most serious. Treating slips and trips as trivial is exactly how serious falls happen.

The legal framework is clear. Under the Health and Safety at Work etc. Act 1974, you have a general duty to ensure, so far as is reasonably practicable, the health and safety of your workers and anyone else affected by your work. The Management of Health and Safety at Work Regulations 1999 require you to assess and control the risk. And the Workplace (Health, Safety and Welfare) Regulations 1992 set specific duties on floors and traffic routes — they must be suitable, kept free from obstructions and from anything that could cause a person to slip, trip or fall. This is not optional good practice; it is the law.

The Main Causes on a Trade Site or Workshop

Slips and trips rarely come out of nowhere. The same handful of causes show up again and again, and once you know them you can design them out. The most common are:

• Trailing leads and hoses: Extension leads, air hoses, vacuum hoses and water lines snaking across a walkway are the classic trip hazard on any trade site.
• Uneven or changing surfaces: Steps you don't expect, raised thresholds, half-laid floors, changes in level between rooms, and ramps without clear marking all catch people out.
• Poor housekeeping: Materials, offcuts, packaging, tools and waste left lying around in walkways. This is the single most preventable cause and the most common.
• Spills and wet or muddy conditions: Water, mortar, paint, oil and adhesive spills — plus mud walked in from outside — turn a safe floor into a slip hazard in seconds.
• Poor lighting: Dark stairwells, unlit basements, plant rooms and corridors hide the very hazards people need to see and avoid.
• Holes, openings and trip steps: Uncovered floor openings, service ducts, drainage channels and small unmarked changes in level.
• Rushing: Carrying loads that block the view, hurrying to hit a deadline, or taking shortcuts across cluttered areas. Pace is a hazard in its own right.

Controls That Actually Work

The good news is that almost every slip and trip is preventable with simple, low-cost controls. The single highest-impact one is good housekeeping — it costs nothing but discipline, and it removes more hazards than any piece of kit.

Good Housekeeping

Keep walkways clear. Store materials tidily and off the route rather than dumping them where they land. Manage waste continuously — bag offcuts and packaging as you go rather than letting them build up. Run cables and hoses overhead where you can, or protect them in covered trunking or cable ramps so they cannot be tripped over. The principle is simple: tidy as you go, not at the end of the day.

Walkways and Routes

Keep designated pedestrian routes clear and well lit. Separate them from plant and vehicle traffic so workers are never sharing a path with a forklift, dumper or telehandler. Mark the routes clearly so everyone — including visitors and other trades — knows where to walk.

Spills, Mud and Wet Conditions

Deal with spills the moment they happen — clean them up and dry the area, or barrier it off until it is safe. Manage mud at entrances with boot scrapers, matting and a routine for clearing it, so it is not walked through the whole site. Wet and muddy floors are responsible for a large share of slips, and the fix is almost always speed: act immediately rather than waiting.

Holes and Openings

Cover or guard every hole and opening — floor penetrations, service ducts, stairwell voids and unfinished openings. Covers must be secured so they cannot slide or be lifted accidentally, and clearly marked. An uncovered opening combines a trip hazard with a fall-from-height risk, which is exactly the combination that causes serious injury.

Footwear

Suitable footwear with good grip is part of the answer — slip-resistant safety footwear where the conditions call for it. But footwear and other PPE are a backup to good housekeeping, never a substitute for it. The right boots help on a floor that is occasionally wet; they do not make a cluttered, badly lit, uneven site safe.

Lighting and Weather

People cannot avoid a hazard they cannot see. Provide temporary lighting in dark areas — stairwells, basements, plant rooms, internal corridors before the permanent lighting is commissioned — so walkways and obstacles are clearly visible. Good light is one of the cheapest slip and trip controls there is.

Weather changes the picture daily. In ice and snow, grit and clear walkways, entrances, ramps and steps before work starts, and keep on top of it through the day. In wet weather, the main job is managing mud transfer — boot cleaning at entrances, matting inside doorways, and clearing any mud or standing water that gets walked in. A site that is safe in July can be treacherous in December if nobody adjusts.

Whose Job Is It?

Everyone's. Slips and trips are not a problem you delegate to one person — the hazards are created and removed by whoever is working in the area, minute by minute. The way you make that stick is to build it into your routines:

• Site induction: Set the housekeeping standard on day one. Tell every worker and visitor where the pedestrian routes are and what is expected.
• Toolbox talks: Cover slips, trips and falls regularly — they are common precisely because people stop noticing the hazards. A short, specific talk resets attention.
• Daily checks: Walk the routes at the start and end of each day. Are walkways clear? Are cables managed? Are spills dealt with? Are openings covered?
• Near misses: Report and act on them. A near miss — someone who stumbled but caught themselves — is a free warning. Treat it as the injury that nearly happened and fix the cause.

Footwear and PPE — Get the Order Right

Appropriate slip-resistant safety footwear matters, and on sites where wet, oily or muddy conditions are unavoidable it is essential. But it sits at the bottom of the control hierarchy for a reason. PPE protects one person, only when worn correctly, and only against the residual risk that better controls have not already removed.

The right sequence is: design out the hazard first (housekeeping, cable management, covered openings), control the conditions (lighting, spill response, gritting), and then provide footwear as the final layer. An employer who hands out grippy boots but tolerates a cluttered, badly lit site has the order backwards — and is not meeting their legal duty.

Quick Reference: Hazard vs Control

The Bottom Line

Slips, trips and falls are the most common injury on UK sites because they are the easiest to ignore — right up until someone is off work, you're short-handed, and the paperwork lands on your desk. None of the controls are expensive or complicated. Keep walkways clear, manage cables and spills, light the dark spots, cover the holes, sort the right footwear, and tidy as you go. Build it into induction, toolbox talks and daily checks, act on near misses, and treat housekeeping as everyone's job. Get that right and you remove the bulk of the risk before it ever has a chance to put someone on the floor.
