Ladder safety: 3 checks before a shelf stock count

Key takeaways

• Review how counters will reach high stock.
• Read ladder labels and inspect equipment before the count.
• Measure setup distances rather than guessing.
• Prepare counting equipment on the ground.

A full shelf stock count is one of the busiest days in an independent shop's stockroom. People move between aisles, pull boxes off high shelves, reset bins, and work against a deadline to get the numbers right. Everyone is focused on the count, and that focus is exactly when safety slips. Ladders tend to show up in the middle of all that. Someone grabs the nearest stepladder, another person leans a straight ladder against a rack, and the count keeps moving.

That habit is where people get hurt. Before your next count, take a few minutes to check three ladder facts. They come from published guidance from WorkSafe New Zealand. That guidance is written for New Zealand workplaces, so check the rules that apply where you work. The three facts still matter in most stockrooms, because they cover what ladders are meant for, what a ladder must be rated to carry, and how to set one up before anyone climbs.

Owners, managers, and staff all have a part in this. Owners decide what equipment is bought and kept. Managers write the count plan and assign the work. Staff notice when a ladder is damaged or when a shortcut is being taken, and they should feel free to say so. A safe count depends on all three groups doing their share.

This post is general information, not advice for your particular site. If you are unsure what applies to your business, ask your regulator or a qualified safety adviser.

Fact 1: Ladders are for short, light jobs

The first fact is about purpose. WorkSafe New Zealand explains that ladders are primarily a means of access to carry out light tasks that are of short duration. Its own examples are changing a light bulb or touching up paint. Those jobs have something in common: the person is on the ladder for a short time, and the work is not demanding.

A full shelf count is not that kind of job. It means standing at height for long stretches while reading labels, counting units, and entering numbers into a handheld scanner or a tally sheet. It often means reaching sideways with one hand while holding a box or a tote in the other. The person is concentrating on the count, not on their footing, and the job goes on for hours. That is a long task at height, and a ladder is a poor place to do it.

Think about a common scene. A counter starts on the floor, works down an aisle, and reaches a high bin. They climb, count, climb down, and move on. Then the next high bin is also a climb. By the afternoon, the same person has been up and down a dozen times with a scanner in one hand and a clipboard tucked under an arm. Each climb looks small on its own. Together they are the kind of repeated risk that adds up.

Managers have a role here too. A count often runs against a deadline, and staff feel pressure to finish. If the manager says out loud that a slower, safer method is acceptable, counters are far more likely to stop and ask before they climb. If the message is that the count must be done by a certain time no matter what, the ladder becomes the fastest option, and that is the wrong reason to use it.

Start with a walk-through. Before the count, walk the stockroom and mark every shelf or bin that someone would have to climb to reach. For each one, decide how the count will happen: from the floor, from a work platform set up for the job, or by moving the stock to a lower level before the count starts. If the only answer is "stand on a ladder," stop and ask whether the task is really short and light. For most full counts, it is not.

This is not a rule against ladders. A ladder can still help someone reach a single high bin for a quick check. What it should not do is become the plan for a whole day of counting. Match the tool to the job, write the method down, and make sure every counter follows the same approach. For the wider count plan, see the guide to physical inventory reconciliation.

Fact 2: Check the rating and the standard

The second fact is about the ladder itself. WorkSafe New Zealand's guidance says that ladders should be of industrial rating (minimum 120kg) and meet, or exceed, the requirements of the relevant AS/NZS 1892 Portable ladders standard.

For a stockroom, that gives you three checks to make before the count:

• Rating. Look for an industrial rating on the ladder or its label.
• Standard. Look for a statement that the ladder meets the standard named above. If the label is unclear, ask your supplier which standard applies to the ladder where you are.
• Load. Think about the total weight on the ladder, not just the person climbing it. Scanners, clipboards, totes, and boxes all add weight, and a counter who carries them up is putting that load on the ladder too.

The rating is not a formality. A ladder rated for light household use may not be built for the daily demands of a stockroom. The label tells you what the ladder was designed for, so read it before you rely on the ladder. Look at the wording, not just the color or the brand. If the rating is missing, faded, or unclear, treat the ladder as unverified and do not use it for the count.

Next, look at the condition of each ladder. Check for cracked or bent rungs, loose feet, worn treads, damaged hinges on stepladders, missing labels, and anything that wobbles when you test it. A ladder with a fault should come out of use right away. Tag it so no one picks it up by mistake, and move it out of the working area until it is repaired or replaced. Stockrooms often collect spare ladders from past projects. Do not assume an old ladder is fine because it has been sitting in the corner. Look at it, read its label, and decide before the count starts.

Fact 3: Set up the ladder before anyone climbs

The third fact is about setup. WorkSafe New Zealand says to place straight ladders 1m out at the base for every 4m of height for stability. That is a ratio you can measure with a tape.

Illustrative example: Calculate the base distance

For illustration, a straight ladder reaching 4 m high needs its base 1 m out: 4 divided by 4 is 1. Measure the distance rather than guessing by eye, and mark the spot on the floor if the same ladder will be used more than once that day.

Check the ground and nearby lines

Do not use boxes, pallets, or stacked stock as a base for a ladder. Stockroom floors can be uneven, and a stack of cartons can shift under load. Set the base on firm, level ground, and check that the feet sit flat before anyone steps on. A ladder that moves at the bottom is much harder to control at the top.

Stepladders have their own check. The guidance says to ensure the stepladder is at least 4m clear of power lines. Stockrooms often sit beside loading docks, yards, or parking areas where overhead lines run close to the building. Before you set up a stepladder near a door to the outside, look up. Note any overhead wires and keep the stepladder well clear of them. If you are not sure whether a line is a power line, ask the utility company or the building owner before you work near it. Do not guess.

The same guidance also says to eliminate the chances of a fall by doing as much preparation work as possible on the ground. For a count, that means doing the setup before anyone climbs. Print the tally sheets. Charge the scanners. Load the labels. Sort the bins by height so the time on the ladder is as short as possible. Set out the tote or cart that will hold the counted stock, so no one has to climb with it in hand. Every trip up and down the ladder is another chance to fall, and most of those trips can be cut by preparing on the ground first. If labels need attention, review the guide to retail barcode label printing during this preparation.

A simple setup routine runs in order:

1. Pick a ladder that has passed its rating, standard, and condition checks.
2. Check the base using the ground checks above.
3. For a straight ladder, measure the distance from the wall or rack using the ratio above.
4. For a stepladder, check the power line clearance described above.
5. Confirm the counter has everything they need on the ground.
6. Only then climb.

Plan the count so people climb less

Ladder checks reduce risk, but the better fix is to plan the count so people climb as little as possible. The guidance also advises that you consider control measures when selecting the best way to work at height. A control measure is a change that removes a hazard or reduces the risk it creates. In a stockroom, control measures for the count can look like this:

• Count all high bins in one batch, from one setup, instead of climbing for each bin as you pass it.
• Move small, high-value, or frequently used items to a lower shelf before the count, so they can be counted from the floor.
• Count floor-level stock first, and leave the high bins until the setup is ready.
• Keep aisles clear of boxes, cords, and pallets, so the walk to the ladder and the walk around it have room.
• Assign one person to be the ladder checker, who confirms each setup before anyone climbs.

The same guidance also says you should minimise the risk of a fall by taking actions to prevent it. That is a reminder to keep thinking about prevention during the whole count, not just at the start. If the count runs long, or if a counter says the ladder feels unstable, stop and reset. A short pause costs far less than a fall.

Write the plan down. A list of control measures that lives only in the manager's head will be forgotten by the afternoon. Put it on the count sheet or on the stockroom wall. Name the person who checks ladders, the person who decides when a high bin needs a different method, and the person who can stop the count if something looks wrong. Tell every counter the plan before they start, not halfway through the day when the first climb already looks like the easy option.

If someone gets hurt

Even with good planning, things can go wrong. If someone falls or is hurt during the count, the first priority is the person. Stop the work, follow your first aid training, and get qualified help. Do not let the count restart until the person is looked after and the area is safe again.

After the person is safe, tell whoever handles safety at your business, and write down what happened. Record where the ladder was, how it was set up, what was being carried, and what the counter was doing. Do not blame the person before you know the facts. A written record helps you find the cause, so you can change the plan. Check what your local rules require for reporting and record keeping, because those requirements vary by place.

Questions before the count

Can staff bring a ladder from home?

A personal ladder needs the same checks as any other ladder. A ladder that works well for painting a wall may not have the rating or the standard you need for a daily count. If a personal ladder is in the building, treat it like any other ladder.

Does the straight-ladder ratio apply to stepladders?

The cited base-distance ratio is for straight ladders. Use the separate stepladder clearance check above when planning work near power lines.
