How heavy is an archive box, and how should you move it?
A standard Type 1 archive box packed full of paper weighs roughly 15 to 20 kilograms, and an over-filled one can weigh more. That puts it at the top of the range most people can lift comfortably from the floor, and well beyond what anyone should be lifting from a top shelf, carrying down fire stairs or moving nine of in a row on a Friday afternoon. It is the most common serious lift in an office, and the way to move it safely is mostly decided before you touch it: how full it was packed, where it was stored, whether there is a trolley, and whether the job can wait.

Why the archive box is the office lift that hurts people
Three things combine. The box is heavy for its size and gives no clue to its weight until you lift it, because an archive box of light stationery and an archive box of dense ledgers look identical. It is stored in places designed for capacity rather than access: top shelves, compactus bottom bays, under desks. And it is moved in bursts, during a purge, an office move or a storeroom clear-out, by people who do it a few times a year and are usually in a hurry.
None of those is a technique problem. A perfect lift does not reduce the weight of the box or the height of the shelf. The risk factors from the Hazardous Manual Tasks Code of Practice that apply here are high force, awkward posture from reaching above the shoulder or below the knee, and repetition when boxes are moved in quantity. The controls that work address those factors directly.
There is no legal maximum weight for an archive box or for any lift in Australian WHS law. The duty is to assess and control the risk of the task, not to stay under a number. A 12 kg box lifted from a shelf at two metres can be more hazardous than a 20 kg box slid off a waist-height trolley.
Pack it so it can be moved
The weight of an archive box is decided when it is packed, usually by someone who will never carry it. Filling to a marked line, or to about two-thirds rather than to the lid, keeps a box towards the lower end of its weight range. Writing the approximate weight or simply "heavy" on the label gives the next person the information they need to plan. Old boxes lose their bottoms; check the base and the handholds before lifting anything that has been in storage for years.
Where a records procedure exists, these steps belong in it. A two-person or trolley-only rule for full boxes, written down and known, is an administrative control that costs nothing and removes the argument at 4.30 pm about whether it is fine to carry just this one.
- Pack to a fill line, not to the lid
- Label the weight, or at least mark heavy boxes
- One box at a time, never stacked in your arms
- Check the base and handholds of old boxes before you lift
Store it where it can be reached
Full boxes belong between knee and shoulder height. The top shelf is for empty boxes and light, rarely used items, and the floor is for nothing you will have to lift. In compactus units, open the aisle fully before reaching in, and use a platform step for upper bays rather than stretching; never lean into a bottom bay and lift at arm's length. A storeroom laid out this way removes the worst postures from the task before anyone decides how to lift.
When storage is being designed or refitted, this is the moment to raise it. Placing the archive room near the goods lift, keeping the heaviest shelving at waist height and marking a parking bay for a trolley and a step costs almost nothing on paper and a great deal after the first injury. Consultation with the people who actually move the boxes is part of the employer's duty, and this is one of the questions it should answer.
Move it on wheels, and know when it needs two people or a wait
A document trolley or platform trolley is the primary control for moving archive boxes any distance. Load it at the shelf, push rather than pull, take the lift rather than a ramp wherever one exists, and do not stack it so high you cannot see. If the lift is out of order, the boxes wait. A full archive box does not go down fire stairs in someone's arms: you cannot see your feet, you cannot hold the rail, and a stumble with a load is a fall with the load on top of you.
Two people are needed when a box must be lifted from above shoulder height or from the floor in a confined space, when its weight is unknown or clearly at the top of the range, or when the route involves steps, thresholds or a door that will not stay open. For large purges, the better answer is often that staff do not carry at all: records or facilities arrange collection from the floor, or the offsite storage provider collects from where the boxes are packed.
This is the content of Module 6, Workstations, Storage and the Occasional Heavy Lift, which covers archive boxes alongside paper cartons, water bottles, monitors and event gear, and of Module 7, Equipment, Aids and Tools for Offices and General Workplaces, which covers trolleys, sack trucks and platform steps and how to check them. Module 5, Safe Movement Principles, covers the two-minute plan and the decision not to lift. What the course cannot do is buy the trolley, book the lift or change the records procedure; those are your employer's controls, and they sit above training in the hierarchy.
