Stockroom ladder setup: 6 checks before a count

Key takeaways

• Read the grade label before assigning a ladder.
• Remove damaged equipment from use.
• Measure the setup rather than guessing.
• Resolve access and anchor questions before the count starts.

Why high shelves need a plan

Every cycle count and full stock count reaches the top shelves sooner or later. Someone has to climb, read labels, and call numbers down to a clipboard or handheld scanner while standing on a step or leaning against a rail. Ladders are a normal part of stockroom work, but they are also a known source of serious injury.

The Canadian Centre for Occupational Health and Safety (CCOHS) puts it directly: falls from portable ladders are a major source of serious injury. That is worth remembering when a count is running behind and someone says they will just grab the boxes from the top shelf and be done in a minute.

Counting high shelves becomes dangerous when people rush, pick the wrong ladder, or climb without thinking about where their feet and hands will go. A few minutes of setup before anyone climbs can prevent many of those problems.

This post covers six checks to make before a stock count starts. It is written for owners, managers, and staff who climb ladders during cycle counts and full stock counts. Owners and managers set the rules for this work. They decide which ladders are bought, how counts are scheduled, and whether there is time in the plan for a safe climb. The checks here are general guidance. Your local rules, your insurer, and the ladder maker's instructions may ask for more, so treat this list as a starting point rather than a replacement for them.

Check 1: Pick a ladder grade that fits the work

Not every ladder is built for the same job. The CCOHS guidance on portable ladders notes that portable ladders are available in various grades: light duty or grade 3; medium duty or grade 2; heavy duty or grade 1. The grade tells you what kind of use a ladder is designed for, so it should match the work your team does on it.

A light-duty household step ladder may be fine for changing a light bulb. It is a poor match for a stockroom where people climb many times a day, carry scanners and tools, and sometimes lift boxes as they go. Look for the grade label on every ladder before anyone uses it. If a ladder has no readable label, set it aside until someone can confirm what it is.

The same CCOHS page points readers to a standard for more detail. It says to refer to the CSA Z11-18 (R2022) Portable Ladders standard or the most current version for more requirements. Ask your safety contact for a copy of the current standard, or a summary of it, and keep it with your safety file. When the standard is updated, check whether your ladders still meet it.

Write the grade of each ladder on your ladder log or on the count plan. That way the person assigning the count can choose the right ladder without guessing. Nobody should have to remember which one is the sturdy one in the back corner.

Check 2: Inspect the ladder before it goes up

Inspect the ladder before each count, not only when it looks old. A new ladder can be knocked out of shape by a bump in a busy stockroom, and an old one can look sound while hiding a loose part.

Walk around each ladder and look at it from more than one side. Check for:

• Cracked, bent, or loose rungs and steps
• Loose rivets, screws, bolts, or hinge pins
• Damaged, worn, or missing feet or non-slip pads
• Cracks, splits, or dents in the rails
• Oil, grease, paint, or wet product on the steps
• On a step ladder, a spreader or lock that does not hold firmly

If anything is wrong, tag the ladder out of service and take it out of the stockroom until it is repaired or replaced. A written tag is clearer than a note saying "be careful with this one." Do not leave a damaged ladder leaning in an aisle, because the next person may not know it is broken.

Check the floor where the ladder will stand, too. The base should be level, clean, and free of pallet wrap, cardboard, spilled liquid, and loose product. A ladder on an uneven pallet, a sloping dock plate, or a sheet of loose plastic is much harder to control than one on flat, clear ground. Do not stand a ladder on boxes, crates, or pallets to gain extra height. That is one of the quickest ways to end up with a ladder that moves under you.

Last, check the area around the ladder. If other people will walk past, put up a sign or cone so that no one walks into the base while someone is on the rungs. Aisles and shelves nearby should be clear of carts and pallet jacks, so the climber has room to step off and nothing rolls into the ladder. Review nearby material storage arrangements while planning the clear space.

Check 3: Set the angle with the 4-to-1 rule

The angle of a leaning ladder matters more than most people expect. The CCOHS page describes the 4-to-1 Rule and says: for every 4 feet (1.2 metres) up, place the base of your ladder 1 foot (0.3 metres) from the wall or upper support it rests against.

The same guidance adds that this placement will set up the ladder with a pitch of 75 degrees, creating the ideal angle for climber balance, ladder strength, and helps prevent the ladder from slipping.

Measure the vertical height from the ground to the upper support, then set the horizontal distance from the wall to the ladder feet at one quarter of that height. A tape measure works well. Some teams mark the floor with tape at the most common set-up positions, so the same spot is used every time and nobody has to judge it again.

The 4-to-1 rule is written for a ladder that rests against a wall or another upper support. A free-standing step ladder is set up differently. Follow the manufacturer's instructions for opening it fully and locking the spreader before anyone steps on it. Do not assume a step ladder that looks open is locked.

Once the ladder is in place, test it before you climb. Press on the rails and try to move the base. If the base shifts, stop, clear the floor, and reset the ladder. Do not climb to see whether it holds. Testing takes seconds, and a slip takes less time than that.

Illustrative example: planning a count section

An illustrative count covers 10 shelf sections. Before assigning the high sections, the supervisor checks the ladder label, inspection record, working height, and whether the task needs both hands. If the planned anchor cannot be confirmed as suitable, those sections need a different access plan before counting begins.

Check 4: Extend the ladder past the point you step onto

If the count requires access to a landing platform, plan the transfer before climbing. When that happens, the ladder has to reach beyond the point where you step. CCOHS says that a ladder should extend at least 1 m (3 ft) above the landing platform or the point of support before you step off onto that surface.

That extension gives you something to hold while you transfer your weight. If the ladder is too short for the shelf you need, do not try to make up the difference by stretching or by balancing on the top steps. Choose another way to reach the shelf, or plan that section for a different day.

Plan the reach before you climb. Decide how far you will need to lean for each box, and whether you can reach it from the ladder without moving your feet. Reaching to the side pulls your weight away from the ladder and makes it easy to lose your balance. If an item is out of reach, come down, move the ladder, and climb again. Moving the ladder takes a few seconds and keeps you centred over the rails.

Keep your body centred between the side rails at all times. Keep both feet on the rungs, and keep one hand on the ladder when you are not holding something essential. If the work needs both hands, read Check 5 before you climb, because that changes what you need in place.

Check 5: Decide when you need a harness and anchor

This is the check where most stockrooms need the most thought. CCOHS says to wear a safety harness and tie the lanyard off to a proper anchor when working 3 m (10 ft) or more off the ground or when working with both hands. The anchor can be a designed fixed support, a temporary fixed support, or an existing structural feature or equipment.

Think about where your body will be, not just where the box sits. A shelf that looks ordinary on a plan may put the climber's feet well above 3 m once they stand on the ladder. Measure the working height before the count starts, and write it on the count plan so the requirement is visible to everyone.

Many counts involve holding a scanner in one hand and a box in the other, or writing on a clipboard while holding a rail. Review the actual hand movements before assigning the task.

Do not assume a rack or shelf is a proper anchor. Someone with the right knowledge should confirm what is available and that it is suitable for the load. If you cannot find a proper anchor for the height and task, change the plan. Use a different method, a different section for that day, or a different set-up.

Only people trained to use the harness should wear it, and the harness and lanyard should be inspected before every use. Keep a record of training in the same file as the ladder log, so the person assigning the work can see who is trained and who is not. Training must cover how to fit the harness.

Check 6: Plan the count around the climb

The last check is about the day itself. The best ladder can still lead to a fall if the count is rushed or the stockroom is busy. Before the count starts, walk through the plan with everyone who will be involved, including people who are not climbing but will be working nearby.

• Schedule high-shelf sections for quieter times, when there are fewer carts, forklifts, and people in the aisles.
• Assign one person to each ladder at a time. If the plan calls for someone to steady the base, name that person before the climb starts and tell them exactly what to do.
• Stage everything at the bottom of the ladder: the count sheet, the scanner, labels, markers, and a container for items that come down. Do not carry loose items up the ladder.
• Use a tool pouch or a lanyard for small items, so both hands stay free for the rungs and the rails.
• Group items by shelf section so one climb covers as much as possible, rather than climbing again for each item.
• Tell the team which aisle has a ladder in use, and keep that aisle closed until the section is done.
• Agree on a rule that anyone can stop the work. If a ladder wobbles, footing feels unsure, or a shelf looks loose, the person on the ladder comes down and the plan is reset.

Make sure someone knows where each person is working, and that a phone or radio is within reach at the base of the ladder. Calling for help is much easier when the people nearby already know what the plan is and where the climber is. A quiet stockroom with no one nearby is a bad place to find out that help is needed.

For the wider counting process, use the guide to physical inventory reconciliation alongside the access plan.

Who should climb, and who should not

Not everyone should climb a ladder during a count, even when they are willing. Before someone is assigned a high section, a supervisor should confirm that the person has been shown how to use the ladder and any harness that the plan requires. Training should be recorded, and it should be refreshed when equipment or the layout of the stockroom changes.

Some conditions call for a different plan. Anyone who feels dizzy, unwell, or unsteady should not climb that day, and should tell a supervisor before the count starts. If a person is taking medicine that may affect balance, they should talk with their supervisor or health provider before climbing. Those conversations are private and should not be a source of embarrassment. They are part of making a count safe for everyone.

Pairing can help, but it must be done properly. A helper who is holding the base needs to know what to watch for, what to say if something looks wrong, and what to do if the climber calls out. A helper who is distracted by a phone or a conversation is not a safety measure. Make sure the helper knows that stopping the work is their job too.

Finally, do not let the count become a race. Set realistic targets for each shift, and tell the team that a slower count with no injuries is the correct result. Owners and managers who reward speed over safety teach staff that it is acceptable to take shortcuts on a ladder. Owners and managers who reward a safe finish teach the opposite.

If something goes wrong

Even with good planning, a near miss or a fall can happen. If it does, the first step is to make sure the injured person gets help. Follow your workplace first aid arrangements, and call for emergency help when the situation needs it. Do not move the person more than necessary, and do not send someone back up the ladder to finish the task while the incident is still being handled.

After that, do three things. Report the incident to a supervisor or safety contact the same day. Tag the ladder out of service if it was involved, and keep it out of use until someone has checked it. Then review the count plan, and ask whether the rush, the wrong ladder, the missing anchor, or the lack of a helper contributed to what happened.

Write down what you learned, and update the ladder log and the count plan to match. A near miss that leads to a better plan costs far less than a fall that teaches the same lesson.

Before the next count

Today, take the count plan to the stockroom and identify the high-shelf sections that need ladder access. Record which ladder and access method each section needs before assigning the work.
