Harnesses
Safety harnesses are what you reach for when the job puts you off the deck. Built for fall arrest and restraint, they matter on roofs, scaffold and MEWPs.
When you're working at height, guessing with PPE is how lads get hurt. A proper full body safety harness spreads load where it should, gives you the right attachment points, and suits the job in front of you, whether that's roofing, scaffold work, steel, or access platforms. Pick a construction safety harness that matches the task, the lanyard, and the standard required, then get the right kit sorted.
What Are Safety Harnesses Used For?
- Working on pitched roofs, a roof safety harness gives you a proper fall arrest or restraint option when you're fixing battens, installing membrane, or moving along exposed edges.
- Climbing and moving on scaffold, a scaffold safety harness helps protect operatives where there is a real risk of a fall during erection, alteration, or short-duration access work.
- Operating from a MEWP, a working at height harness is used with the correct lanyard to reduce the risk of ejection from the basket if the machine is jolted or struck.
- Carrying out steelwork, telecoms, or access installation, a full body safety harness with a dorsal D ring gives you the correct attachment point for fall arrest systems.
- Using a positioning harness for hands-free work, it helps hold you in place on structures or towers while you fit, bolt, or adjust components without overreaching.
Who Uses These on Site?
- Roofers use safety harnesses when they're exposed on pitched roofs, fragile surfaces, or edge work, especially during strip-outs, repairs, and new coverings.
- Scaffolders rely on a scaffold safety harness during erection and alteration work where collective protection is not yet fully in place and movement is constant.
- Steel erectors and cladding teams wear a fall arrest harness when connecting steel, fixing rails, or working near open edges where a slip has serious consequences.
- MEWP operators need a working at height harness suited to platform use, usually clipped in for restraint so they stay inside the basket during sudden movement.
- Maintenance teams, industrial fitters, and inspection engineers keep a construction safety harness ready for plant rooms, access gantries, and awkward high-level checks.
Choosing the Right Safety Harness
Sorting the right one is simple. Match the harness to the height job, the anchor setup, and how you actually work.
1. Fall Arrest or Work Positioning
If you need protection from a real fall, buy a full body safety harness rated for fall arrest with the correct attachment point, usually a dorsal D ring. If the job is hands-free support on a structure, look at a positioning harness, but do not confuse positioning with fall arrest.
2. Job Type and Access Method
If you are in a MEWP, you usually want a harness suited to restraint so you stay in the basket. If you are on scaffold or roofing work, think harder about movement, snag risk, and whether you need rear attachment only or extra points for specific tasks.
3. Fit Matters More Than Most People Think
Do not buy a loose safety body harness and hope it will do. If the straps ride up, the chest section sits wrong, or there is too much slack, it will be uncomfortable all day and can perform badly in a fall. Size it properly over the clothing you actually wear on site.
4. Check the Standards and Compatibility
If it is for fall arrest, make sure the harness meets the right standard and that your lanyard, anchor device, and rescue plan all work together. A harness on its own is only part of the system, so do not mix kit blindly just because the clips seem to fit.
The Basics: Understanding Safety Harnesses
The important bit is not just wearing a harness. It is knowing what type it is designed to do on site and where you are meant to connect it.
1. Full Body Harness for Fall Arrest
A full body safety harness spreads the forces of a fall across the body more safely than a belt ever could. For most fall arrest jobs, the key point is the dorsal D ring on the back, which is where the system connects.
2. Restraint Stops You Reaching the Edge
A restraint setup is there to stop you getting into the fall zone in the first place. That is common in MEWP work and some roof tasks, where the aim is to limit travel rather than catch you after a drop.
3. Positioning Harnesses Hold You in Place
A positioning harness or belt setup supports you while you work with both hands, often on structures or towers. It is useful for access and control, but it is not a stand-alone answer for fall arrest unless the rest of the system is built for it.
Safety Harness Accessories That Actually Matter
The harness is only one part of the setup. These are the extras that stop bad fitting, poor compatibility, and wasted trips back to the van.
1. Shock Absorbing Lanyards
This is the bit too many people treat as an afterthought. A proper shock absorbing lanyard is there to manage fall forces. Get the wrong length or type and you can create clearance problems or a setup that does not suit the task.
2. Anchorage Connectors
Slings, anchor straps, and connectors give you a safe way to tie into the structure you are actually working from. Without the right anchorage point, the harness is just something you are wearing.
3. Tool Lanyards
If you are working above others, dropped kit is as much a problem as a slip. Tool lanyards stop spanners, drills, and fixings raining down off scaffold, platforms, and roof edges.
4. Storage Bags and Inspection Tags
Chucking a harness in the back of the van with wet gear and sharp tools ruins it fast. A proper bag and clear inspection record help keep the webbing clean, dry, and traceable between checks.

Common Buying and Usage Mistakes
- Buying by price alone and ignoring the task usually ends with the wrong harness for the job. A roofing setup, a scaffold setup, and a MEWP restraint setup are not all the same thing.
- Guessing the size is a common one. If the harness is too loose, it shifts about, rubs all day, and may not sit correctly if there is a fall, so size it over your actual site layers.
- Mixing any old lanyard with any harness is asking for trouble. The system has to be compatible, rated correctly, and planned around anchor points and clearance, not just clipped together because it fits.
- Using a belt or positioning setup where proper fall arrest is needed is a serious error. Positioning kit helps you work hands-free, but it is not a substitute for a fall arrest harness where there is a real drop.
- Ignoring inspection, damage, and storage shortens the life of the kit fast. Dirty webbing, cuts, paint, concrete splash, or bent hardware mean it needs checking properly before it goes back into use.
Full Body Safety Harness vs Positioning Harness vs Safety Belt
Full Body Safety Harness
This is the standard choice where fall arrest is needed. It spreads load across the body and is the right call for roofing, scaffold, steel, and general height work where a real fall risk exists.
Positioning Harness
This is for holding you in place so you can work hands-free on structures, towers, or access tasks. Useful when fitted correctly, but it is not the one to rely on alone for fall arrest unless the whole system is designed for it.
Safety Belt
A belt on its own is not the same as a fall arrest harness. It may have a place in positioning or restraint setups, but for modern fall protection work, a full body harness is the safer and expected route.
Maintenance and Care
Check Webbing Before Every Shift
Run your hands over the straps and look for cuts, fraying, burns, pulled stitching, paint, concrete, or chemical marks. If the webbing looks suspect, take it out of service and get it checked properly.
Inspect Buckles and D Rings
Metalwork takes a hammering on site. Check buckles, adjusters, and any dorsal D ring for cracks, distortion, corrosion, or rough edges that could damage the straps or affect performance.
Clean Off Site Dirt Properly
Dust, mortar, and general site grime soon work into the harness. Clean it in line with the maker's instructions and let it dry naturally. Do not blast it with heat in the drying room and hope for the best.
Store It Dry and Out of the Sun
Leaving a harness wet in the van or piled under sharp kit is a quick way to ruin it. Keep it dry, clean, and away from direct sunlight, oils, and anything that can cut or contaminate the webbing.
Replace After a Fall or Failed Inspection
If the harness has arrested a fall, do not put it back in service. The same goes for kit that fails inspection or has unreadable labels. Height safety gear is not the place to chance another run out of it.

Safety Harness FAQs
Is a safety harness a PPE?
Yes. A safety harness is classed as personal protective equipment for work at height. It is there to protect the wearer as part of a properly planned fall protection system, but it still needs the correct lanyard, anchor point, and inspection regime to do its job.
What is the difference between a safety belt and a safety harness?
A safety belt only supports one area of the body, usually around the waist, while a full body safety harness spreads load across the shoulders, chest, and legs. For fall arrest work, the harness is the right choice. A belt may still be used for positioning in some setups, but it is not a swap-for-swap alternative.
When must a safety harness be worn?
A safety harness must be worn when the risk assessment and method of work say personal fall protection is needed for the task. That is common on roofing, scaffold, steel, and MEWP jobs where there is a real fall risk and other controls alone are not enough.
How many types of safety harnesses are there?
There are several types depending on the work, but on site the main split is between fall arrest harnesses, restraint harnesses, and positioning harnesses. You will also see task-specific versions for scaffold, roofing, tower work, rescue, and access work, so the right answer is always tied to the job.
Do all working at height harnesses fit the same, or do I need to size them properly?
No, they do not all fit the same, and yes, proper sizing matters. A badly fitted harness rubs, shifts, and can sit wrong in a fall. Check chest, leg, and torso adjustment, and fit it over the layers you actually wear on site, not just over a T shirt in the stores.
Which safety harness do I need for roofing, scaffolding, or MEWP work?
It depends on the task and the full system, not just the harness on its own. Roofing and scaffold jobs often call for a fall arrest harness, while MEWP work commonly uses a harness in restraint to keep you inside the basket. If you are unsure, match the harness to the risk assessment, anchor method, and lanyard type before buying.
What standard should a safety harness meet for fall arrest?
For fall arrest, you should be checking for the relevant standard marking on the harness and making sure the rest of the system is rated to suit as well. Do not stop at the harness label. The lanyard, connectors, and anchor arrangement all need to match the intended use and site requirements.
Can I use any lanyard with any safety harness?
No. That is one of the easiest ways to end up with an unsafe setup. The lanyard has to be compatible with the harness attachment point, the anchor position, the type of work, and the clearance available below. If those do not line up, you have not got a proper system.
