Workplace safety
The safest way to do work at height indoors
Safety is not a single dimension. The safest way depends on what task you are doing, how often you reposition, and what your facility's doorways and floor look like. This is the honest ranking.
Frame the question correctly
The phrase "safest way to do work at height indoors" is what your insurance carrier wants you to optimise. Optimising it correctly means picking the equipment whose failure modes are not the failure modes that actually hurt your operators.
Workplace fall data from HSE, the Swedish Work Environment Authority, and the EU-OSHA agree on the dominant indoor failure modes: overreach from a ladder, base slip on a smooth floor, fall during reposition between work points, and missing fall arrest above 2 metres on equipment that does not have an anchor. The ranking below sorts equipment by how many of those modes the equipment removes.
The ranking, indoor 2 to 6 metre work
Below is the ranking we use when a customer asks. Higher in the list = safer for the dominant failure modes for indoor work between 2 and 6 metres.
| Rank | Equipment | Removes overreach? | Removes base slip? | Removes reposition fall? | Has fall arrest? |
|---|---|---|---|---|---|
| 1 | Mast lift (EN 280 Type 1 / Group A) | Yes | Yes | Yes | Yes (harness anchor) |
| 2 | Scissor lift (small footprint) | Yes | Yes | Partial | Yes |
| 3 | One-person mobile tower | Yes | Yes | No (must dismantle) | Optional |
| 4 | Erected scaffold (multi-day) | Yes | Yes | N/A (static) | Yes |
| 5 | Podium step | Partial | Yes | No | Optional |
| 6 | Stepladder | No | No | No | No |
The mast lift wins because it is the only category in which all four dominant indoor failure modes are designed out. The operator stands on a guarded platform with a harness anchor, the unit drives between work points at low transit height (no climb-down/up cycle), and EN 280 stability calculations rule out base slip under indoor floor conditions.
Where the ranking changes
Two contexts change the ranking. Static work for half a day or longer in one position: an erected scaffold or a one-man tower can match a mast lift, because the reposition penalty does not apply. Outdoor work or work above 6 metres: the indoor mast lift is no longer the right tool; you are looking at boom lifts, rough-terrain scissors, or rope access.
The decision rule we give customers: if you reposition more than three times during the work, the mast lift wins on safety. If you do not reposition at all and the working height is below 6 metres, a scissor or tower is competitive on safety and may be cheaper.
How to convert this into a buying decision
Three numbers from your operation determine the answer:
- Hours per month above 2 metres indoors. If under 10, hire equipment when needed. If 30+, buy.
- Reposition count per task. Under 3 = a tower works. 3+ = mast lift wins.
- Doorway / elevator constraint. 800 mm doorway clearance and 1.0 m goods elevator → mast lift fits where scissors will not.

Frequently asked questions
What is the safest indoor MEWP for 5 metre work?
An EN 280 Type 1 / Group A mast lift in the 5 metre working-height class is the safest indoor MEWP for repositioning-heavy work. It has a harness anchor, an emergency stop, and an emergency lowering valve. The operator drives between work points at low transit height, eliminating the climb-down/climb-up cycle that introduces fall risk on towers and ladders.
Is a scissor lift safer than a mast lift?
For static single-position work at low to medium height, scissor lifts and mast lifts are comparable on safety. For repositioning-heavy work, the mast lift is safer because the reposition cycle is faster and does not require dismantling. The scissor lift's larger base also excludes it from many indoor doorways and goods elevators.
Do I need a harness on a mast lift?
EN 280 mast lifts have a harness anchor point inside the platform. Whether your operators must use a harness depends on local regulation: in the UK and Sweden, harness use on Type 1 / Group A platforms is required for elevated maintenance tasks but not for routine stockpicking. Your safety officer should confirm based on the specific task profile.
Are mobile towers as safe as mast lifts?
For static work in one position, an erected mobile tower is comparable. For work that requires multiple repositions, the tower is less safe because each reposition involves dismantling, moving frame sections, and re-erecting. The dismantle / re-erect cycle is itself a fall opportunity that the mast lift design eliminates.
