Stopping Operators Climbing Scissor Lift Guardrails

By Christopher Green, UP2IT Access Hire · 16 October 2026 · 7 min read

Most construction sites already ban standing on scissor lift guardrails. Operators sign the induction, the rule is in the SWMS, and there’s a sticker on the platform. Walk the floor for an hour, though, and you’ll probably still see someone with a boot on the mid-rail reaching for that last fixing.

That’s because rail climbing is usually a symptom, not the problem. People rarely climb because they don’t know the rule. They climb because, at that moment, the machine, the site or the schedule makes climbing look like the only way to finish the job. Fix those causes and the climbing mostly stops.

Why it matters

The guardrails are the platform’s primary fall protection. Step on them and you’ve stepped outside the protected envelope, often 4 to 10 metres above a concrete slab. IPAF’s accident data lists standing on guardrails as one of the main ways people fall from platforms, and falls from the platform are almost always fatal or seriously injuring (IPAF).

Watch: what it looks like

This short clip shows exactly the behaviour we’re talking about: a worker climbing onto the guardrail of a scissor lift with no harness.

The short version

• Plan for the highest point of the work, not the ceiling height, and hire a machine that gets the operator there comfortably.
• Clear the floor so the platform can get right up to the work.
• Make repositioning quick and normal, not something that costs a crew time or money.
• Have enough machines so nobody is making do with the wrong one.
• When you see someone on the rails, stop the job and ask why they couldn’t reach. Then fix that cause the same day.

Why people climb the rails

Ask any crew and they’ll tell you. These are the causes we see most often on Auckland sites.

Why paperwork alone doesn’t work

A signed rule sheet tells you the operator knew the rule. It doesn’t change any of the reasons in the table above. Under the Health and Safety at Work Act 2015, the business running the site still has to provide suitable plant, a safe system of work and adequate supervision. WorkSafe lists inadequate supervision and not fully assessing the job, site and equipment among the common causes it finds when it investigates scissor lift injuries (WorkSafe NZ).

1. Plan for the highest point of the work

This is the biggest single fix. Machines are often picked by the ceiling height or the drawings rather than by where the operator actually needs to put their hands.

• Ask the right question. In the task plan, ask the trade: what is the highest thing you need to touch, and how far above it do you need to work? Allow for ceiling services, bulkheads, fixings above beams and tools that need clearance.
• Know the difference between platform height and working height. Working height is usually quoted as platform height plus about 2 m. That assumes someone standing on the deck reaching up, which is fine for a quick task and tiring for a day of overhead work. Choose a machine where the work sits at chest to shoulder height.
• If in doubt, go taller. The extra hire cost of a taller machine is small next to the cost of a fall. A machine that reaches further than needed can always be stopped lower.
• Check the machine when the job changes. A lift that was right for the slab-level fit-out may be too short once you move to the high ceiling in the foyer. Review the machine at each new stage, not just at the start.

2. Let the platform get right up to the work

• Keep access routes clear. Make housekeeping part of the job plan for the areas where lifts will work. Pallets, offcuts and other trades’ gear are what keep platforms back from walls.
• Use the extension deck. Most slab scissors have a roll-out deck that closes the gap to a wall or over a small obstacle. Make sure operators know how to use it and its load limit.
• Sequence the trades. If services go in before the work above them, the scissor can’t get under it. Planning the order of work removes a lot of overreaching.
• Use a boom for up-and-over work. When the work is above pipework, ducts or a grid, a scissor is the wrong machine. A knuckle boom can reach up and over safely.

3. Make repositioning quick and normal

• Remove the penalty. If a crew is paid by the fixing, make it clear that moving the lift is part of the job, not lost time. Build it into programmes and prices.
• Use drive-at-height where it’s allowed. Most slab scissors can be driven slowly while raised on firm, level concrete, within the limits in the manual. Operators who know this reposition far more often.
• Coach it. Make “lower it, move it, raise it” a normal part of the job. Praise it when you see it.

4. Have enough of the right machines

• Match the number of lifts to the work. If three trades need access in the same week, one shared lift guarantees someone will make do.
• Book lifts like any other resource. A simple booking sheet shows who needs which height and when.
• Hire short-term rather than stretch. Bringing in the right machine for a few days is cheaper than a WorkSafe investigation.

5. Keep the platform clear

• Nothing to stand on. Ban buckets, boxes, step ladders and trestles on platforms, and keep material stacks below the mid-rail.
• Long materials need a plan. Sheets and lengths that don’t fit inside the rails lead to climbing and rail removal. Use the right machine or a material-handling accessory approved by the manufacturer.
• Only use what the manufacturer approves. Use only accessories and adjustments approved for that exact machine. Ladders, boxes and rail alterations are never a substitute for the right machine.
• Guardrails stay on and the gate stays shut. Treat a removed or tied-back rail as a stop-work item.

6. Supervision that actually sees it

Rail climbing happens out of sight, at height, when the supervisor is somewhere else. It needs active supervision, not a rule on the wall.

1. Look up. Make checking platforms part of every supervisor walk-around, especially late in the day and near the end of a task.
2. Stop the job, every time. Get the operator back onto the deck and lowered before anything else happens.
3. Ask why they couldn’t reach. Treat the answer as a planning fault until proven otherwise: wrong height, blocked access, wrong machine type, not enough lifts.
4. Fix the cause the same day. Swap the machine, clear the floor or re-sequence the work. If the cause stays, so will the climbing.
5. Record it as a near miss, and record the reach gap. Note where it happened, what the operator was trying to reach and how far short the machine fell. Patterns tell you which trades need taller machines, different machine types or more lifts.

7. Get the crews on side

• Ask them first. In a toolbox talk, ask: “What can’t you reach from the lift you’ve got?” The people climbing know exactly why.
• Make the stakes real. A short talk about a real fall does more than another sign-off sheet. Falls from the platform killed 132 people worldwide between 2012 and 2022 in IPAF’s data alone (IPAF). Recently a worker was killed at an Auckland worksite while standing on guardrails (NZ fatal fall guilty plea, $1.5m fine at stake).
• Be fair and consistent. If the site gave someone the wrong machine, fix the site. If someone climbs when the right machine and a clear floor were there, that’s a disciplinary matter, applied the same way to every trade.
• Hold subcontractors to it. Put machine selection and supervision of platform work into subcontract terms and pre-start meetings, and make their supervisors accountable for their crews.

What about harnesses?

Guardrails are accepted fall protection, but they aren’t perfect: a person can still go over the top rail or through the gap below the mid-rail. That’s why some safety professionals argue for a primary and a secondary layer of protection on scissor lifts.

Use restraint, not arrest. On a scissor lift, a harness clipped to the platform’s marked anchor point with a short restraint lanyard can stop the operator reaching or climbing onto the top rail. Fall arrest is a different story: a self-retracting lifeline needs roughly 1.4 m of clearance and an energy-absorbing lanyard can need over 5 m. At typical scissor working heights, a person could hit the ground before an arrest system catches them.

Use the right anchor. Clip only to the anchor point marked on the machine. A guardrail may not be strong enough to act as an anchor, and many scissor anchors are rated for restraint only. Check the manual and decals.

A harness is never permission to stand on the rails.

Site manager’s checklist

Run through this at the start of each stage of work.

☐ Highest point of the work identified for each trade

☐ Machine height chosen so the work is at chest to shoulder height

☐ Up-and-over work allocated to a boom, not a scissor

☐ Enough lifts on site for the number of trades needing access

☐ Access routes and work areas clear for the platform

☐ Operators trained and familiarised, including the extension deck and drive-at-height

☐ Repositioning built into the programme and the price

☐ No buckets, ladders or stacks on platforms; rails on and gates shut

☐ Supervisors checking platforms on every walk-around

☐ Rail climbing recorded as a near miss and the cause fixed
