How to Use the HSE MAC Tool for Manual Handling
The Manual Handling Assessment Charts, usually called the MAC tool, help employers identify higher-risk lifting, carrying and team handling tasks. HSE developed the tool to make common risk factors visible and help decide which jobs need improvement first. It is most useful when someone can observe the real operation and act on the findings; completing a score sheet without changing the task misses the point.
What the MAC tool covers
The MAC has routes for one-person lifting or lowering, one-person carrying and team handling. It considers factors such as load and frequency, distance from the body, vertical lift zone, twisting, grip, floor conditions and carrying distance, depending on the activity. The assessor records colour bands and scores for the observed factors. More demanding factors attract greater attention.
It is not the tool for every manual handling operation. For pushing and pulling, HSE provides the RAPP tool. For repetitive upper-limb work, the ART tool may be relevant. Variable weights across a regular job may call for V-MAC alongside MAC. HSE says MAC was not designed for handling patients, where the person’s mobility, cooperation and needs change the assessment.
Select a real task
Start with tasks that workers say are hard, have produced complaints or involve awkward loads. Speak to employees and their representatives; they may know where the procedure differs from the way the job is actually done. Observe the full cycle, including collection, travel and placement. If a pallet empties from waist to floor level during a shift, assess the difficult lower lifts rather than a convenient mid-height example.
Choose the correct MAC chart. A task involving both lifting and carrying may need both elements considered. Follow HSE’s current assessment guide, not a guessed score from memory. Record the load, frequency, height, route and other relevant conditions so someone can understand what was assessed later.
Interpret the colours and scores
The traffic-light colours draw attention to factors with greater potential for harm. Total scores help compare tasks and prioritise improvements. They are not legal pass or fail marks, and HSE says the totals do not correspond to fixed action levels. A green factor does not prove that a task is safe for every worker; a red factor tells you where to look urgently for a better control.
Use the result to change the operation. Can the material arrive nearer to point of use? Can heavy items be stored between knee and shoulder height? Would smaller containers, a suitable trolley or a lift table reduce strain? Assess again after the change to see whether exposure has fallen, while checking that you have not introduced another risk.
Know the tool’s limits
A MAC form may not by itself be a suitable and sufficient assessment under the Manual Handling Operations Regulations 1992. Consider an individual’s capability, health, training and any unusual conditions outside the chart. One worker’s back problem, a slippery seasonal entrance or an unstable load may require additional action. If the job is complex, seek competent advice and use HSE’s fuller assessment guidance.
The MAC is an assessment aid for employers and safety representatives; it is not a licence for workers to lift any weight within a colour band. Nor does it make training unnecessary. People still need to know the controls selected, use aids correctly and report when the task changes.
Put the result into practice
Name an owner for each improvement and set a date. Tell workers what is changing and why. Check the revised task on a normal shift. Review the assessment after changes in products, equipment or staffing, an incident, or reports of discomfort. The best MAC exercise is one that visibly improves how the work is done.
Our online manual handling course introduces manual handling hazards and safer decisions. Use HSE’s MAC guidance when you need to assess and improve a specific workplace operation.
Example: repetitive van loading
Suppose workers transfer cartons from a pallet into a van. When the pallet is half empty, the lifts may be waist high; the first or last layers can demand overhead or floor-level reaches. Observe the whole job and record weight, frequency, body position and carrying. Use the relevant MAC chart for lifting and another for carrying if needed. Ask whether van position, pallet height or pace varies.
The result can guide a change: raise the working level, place the pallet closer, reduce package weight or use a suitable conveyor. Repeat the assessment after the change and check that exposure has fallen. If workers also push a loaded cage, assess that element separately using the appropriate HSE guidance.

Questions about scores
Does green mean a task is guaranteed safe? No. MAC colours relate to the factors scored, while health or unusual conditions may require further controls. Does a high total demand one prescribed action? No. HSE uses scores to prioritise tasks and compare improvements; totals have no fixed legal action threshold. Record the change you intend to make, not merely the colour.
