Safeguarding more than your footing: the ground first

Let me explain a simple truth that safety specialists repeat because it saves lives: the most important thing to check before you put anyone in an elevated work platform is the ground surface. It’s not the color of the machine or the exact model that matters most in that moment—it’s whether the ground can carry the weight, stay level, and stay stable while you’re up there. If the ground shifts, leans, or gives way, even the best operator with the most careful plan can end up with a tip, a sway, or a sudden stop.

The reason is straightforward. An EWP is a delicate balance of weight, leverage, and leverage now—because you’re lifting a person, a tool, and often materials high above the ground. Uneven or soft ground can tip the balance. The outriggers, pads, or wheels are designed to spread that load and to anchor the machine, but they can’t do their job if the surface beneath them isn’t trustworthy. So before you raise that platform, you’re looking for one thing: a ground surface that is level, firm, and capable of supporting the EWP’s weight.

What to look for when you arrive on site

Here’s the thing: you’ll notice a dozen practical details in a minute or two, but you’re listening for a few critical signals.

• Level and flatness: The ground should be level within the machine’s tolerance. A slope—even a partial one—can shift the center of gravity once the platform extends. Look for a surface that’s flat enough to set up the outriggers without needing last-minute improvisations.

• Firmness and bearing capacity: The surface should feel solid when you press or walk on it. If you can push a finger into the soil or feel it give under weight, that’s a red flag. In soft soils, you’ll want to pivot to a firmer patch or use stabilization measures.

• Surface material: Concrete, compacted gravel, asphalt, or a properly prepared composite surface are ideal. Mud, loose gravel, loose sand, or gravel with large gaps can spell trouble because they don’t distribute weight evenly.

• Debris and hazards: Clear the area of hoses, cables, ruts, rocks, or spoil piles. Even small debris can cause wheel or outrigger wheel chokes. Check for overhead obstructions too—low branches, ducts, or beams—because you don’t want a collision once you’re up.

• Slopes and irregularities: Short, shallow slopes can be managed with proper outriggers and mats; longer or steeper slopes often require relocating the work or choosing a different setup.

• Weather impact: Recent rain, frost, or heat can change ground conditions quickly. Wet ground is more slippery and less stable; frozen ground can be brittle and crack under load. If conditions are changing, pause and reassess.

• Ground bearing in context: If you’re on a construction site, ask about recent compaction tests or ground bearing capacity data. If you’re in a municipal or indoor setting, check floor load ratings and any temporary supports in place.

Quick, reliable assessment tools and habits

You don’t need a full engineer’s toolkit to size up ground safety. A few practical moves help you decide fast and confidently.

• Visual scan plus touch: Do a quick walk-through to identify cracks, soft spots, or puddles. Then press your heel into the surface in a few spots to gauge firmness.

• Level check: Use a small spirit level or a laser level to confirm the setup surface is level. If the ground tilts noticeably, don’t fight it—adjust your setup or move.

• Outriggers and pads: Inspect the outriggers for any damage and ensure the pads sit squarely on the surface. If the surface isn’t ideal, consider thick, purpose-made mats or plywood plates to stabilize the load path.

• Weight considerations in the moment: Remember that while the EWP has a rated load, the actual load on the surface includes the platform, the operator, tools, and materials. If you’re near the upper end of the capacity, the ground needs to be even more solid.

• Weather-check ritual: As a habit, incorporate a quick weather check—has it rained recently? Is dew on the surface? Temperature swings can alter grip and firmness.

When the ground isn’t ready: practical options

Sometimes the ground just won’t cooperate. That’s not a failure; it’s a signal to adjust the plan.

• Move to firmer ground: If possible, relocate the setup to a level, solid surface nearby. A change of work position can save a lot of risk later.

• Use mats or plates: Heavy-duty anti-slip mats, steel outrigger mats, or thick plywood can distribute weight more evenly and restore stability. Make sure they’re rated for the load and properly tied down if outdoors.

• Stabilizers and outriggers: Some EWPs come with adjustable outriggers or stabilizers. Use them as intended, extend fully, and verify pads are in good contact with the ground. If the ground is marginal, you might need to shorten the extension or place supports under the pads to prevent sinking.

• Reset and re-check: After you lay mats or adjust stabilizers, re-check level, bearing, and all safety interlocks before raising the platform.

• Pause and re-plan: If none of the fixes give you confidence, it’s wise to pause work and arrange a safer alternative—perhaps bring the work to a different location or schedule the task for a day with better ground conditions.

Complementary safety checks that go hand in hand

Ground condition is a foundational element, but it sits among other critical checks.

• Overhead hazards: Look up and around for power lines, ceiling girders, or suspended loads. Even a perfectly stable ground won’t protect you from an overhead issue.

• Access and egress: Ensure safe routes to and from the platform base. A secure approach, free of trip hazards, matters as much as the ground beneath you.

• Communication and team readiness: Clear signals, a ground spotter, and a quick briefing help the crew stay aligned. A small miscommunication can turn a steady setup into a risky one in seconds.

• Equipment readiness: Verify that the EWP’s tires or tracks are in good condition, tires inflated to spec, and the safety devices functioning. A well-prepped machine is part of the stability equation.

A touch of real-world nuance

Here’s a scenario you might recognize: you arrive on a job site with a seemingly flat concrete pad, but there’s a shallow oil slick from a previous spill and a few weathered expansion joints. The surface looks okay at first glance, but a closer inspection reveals tiny slick patches and a couple of high spots near edge seams. You could push ahead, but the odds of a slip or a misalignment when the platform extends are higher. So you pause, clean the area, sweep away slick patches, and use a couple of rigid mats to cover the joints. The setup feels steadier, the word “safe” isn’t just a word anymore, and you can focus on the task at hand with a clear head.

People don’t always realize how small conditions can snowball into big risks. It’s not about being overly cautious; it’s about being practical. Ground readiness buys time for precise work and protects everyone involved. And let’s be honest: when a job depends on you getting a clean, stable platform, the ground becomes your best ally—if you treat it right.

Turning the ground check into a routine

Think of ground assessment as part of a simple, repeatable ritual. Before any lift, take a moment to:

• Look, touch, and listen: Visual cues plus a quick firmness check set the tone.

• Level the base: Confirm level using a level tool; adjust as needed.

• Inspect for hazards: Remove debris, check for moisture, and ensure no hidden cracks or soft spots.

• Prepare with mats or pads: If the surface isn’t ideal, use mats and verify fit.

• Confirm the plan: Re-check weather, surface condition, and load expectations with the team.

That pause can feel small, but it pays back in safety and efficiency. You avoid rework, you avoid near-misses, and you keep the project moving with fewer interruptions.

A final reflection

Safety is a habit, not a rule you memorize and forget. The ground under an elevated work platform is the quiet gatekeeper of everything you’ll do above it. When you treat the ground with respect—when you inspect it, adapt to it, and plan around it—you’re not just following a rule. You’re building confidence, reducing risk, and making the work smoother for everyone on the site.

If you ever watch seasoned crews at work, you’ll notice this: they’re not rushing. They’re methodical, they’re calm, and they’re prepared to adjust. The ground might seem ordinary, but it’s what keeps everything else from tipping the balance. And that, in the end, is the heart of safe EWP operation.

In case you’re looking for practical cornerstone tips, here’s a quick recap:

• Ground condition wins over everything else when it comes to safety.

• Check level, firmness, slope, and debris before lifting.

• Have mats or stabilizers ready if the surface isn’t perfect.

• Reassess after any weather change or surface adjustment.

• Keep the team in the loop and keep the plan flexible.

Ground safety isn’t glamorous, but it’s absolutely essential. Stay curious, stay cautious, and give the ground the attention it deserves. Your future self will thank you for it.
