Work at height

What is working at height and why is it a priority?

Falls from height are one of the leading causes of fatal accidents in Spain and the European Union, particularly in construction, industrial maintenance, facade and roof cleaning, installations, and logistics. Unlike other risks, the severity of a fall does not depend solely on the height: falls from less than two meters result in serious injuries and deaths every year, especially when the fall occurs on edges, machinery, or hard surfaces. Therefore, risk assessment cannot be limited to simply measuring meters.

Spanish regulations address work at height through several standards. Royal Decree 1215/1997, amended by Royal Decree 2177/2004, regulates the use of work equipment for temporary work at height: ladders , scaffolding, and rope access and positioning techniques. Royal Decree 486/1997 on workplaces requires the protection of openings, uneven surfaces, and areas with a risk of falling. Royal Decree 1627/1997 establishes specific provisions for construction sites. And Royal Decree 773/1997 regulates personal protective equipment, including fall arrest systems.

The common principle to all of them is that established by Royal Decree 2177/2004: temporary work at height can only be carried out when weather conditions do not endanger health and safety, with appropriate equipment, giving priority to collective protection measures over individual ones, and with specific training for those who carry them out.

Where does the reference to two meters appear?

The figure of two meters does not define work at height, but it does establish specific obligations in certain regulations:

• Workplaces. Annex I of Royal Decree 486/1997 requires that openings, uneven surfaces and platforms that pose a risk of falling from more than two meters be protected with railings or other equivalent systems, and sets requirements for the height and strength of the railings.
• Construction works. Annex IV of Royal Decree 1627/1997 requires protection against falls from heights of more than two meters by means of railings or other equivalent collective safety protection system, and establishes conditions for scaffolding, platforms and walkways.
• Ladders. Royal Decree 2177/2004 requires that work at heights of more than 3.5 meters from the point of operation to the ground, which requires movements or efforts dangerous to stability, be carried out with a fall arrest system or other alternative measures.

Outside of these specific cases, the general obligation to assess and protect against falls applies to any height. A 1.5-meter platform next to a conveyor belt or a ladder in a warehouse requires assessment and safety measures even if it doesn’t reach the height of the guardrails.

How it is assessed and protected

1. Eliminate working at height where possible: floor assembly, equipment that allows operation from below, design of facilities with permanent safe access.
2. Choose the safest access and work equipment for the task, its duration and its frequency: lifting platforms, scaffolding with guardrails, fixed platforms, rather than ladders or rope techniques.
3. Apply collective protection: complete railings (handrail, intermediate rail and toe board), safety nets, gap covers, lifelines as support for individual protection only when collective protection is not possible.
4. Apply individual protection as a last resort: complete fall arrest system (harness, lanyard with shock absorber or retractable device, suitable anchor point), with verification of the fall factor, free distance and rescue plan.
5. Planning the task: weather conditions, signage and marking, coordination with other activities, presence of preventive resources when the assessment requires it, and work permit when the procedure establishes it.
6. Training and education: specific training on the equipment used, on the placement and verification of fall protection equipment and on rescue.

Organizational application

• Working at height procedure. Defines which tasks are considered, what equipment is authorized for each situation, who can perform them, and when a work permit and preventive resource are required.
• Equipment. Inventory, periodic review and registration of scaffolding, platforms, ladders, lifelines and fall protection equipment, with removal of deteriorated or expired items.
• Contracts. Coordination of business activities for work at height in third-party facilities: information on risks, available protective equipment and monitoring of training of external personnel.
• Rescue. Rescue plan for any job with a fall arrest system: a person suspended in a harness needs to be rescued within minutes.
• Supervision. Inspection of protective equipment before each use and presence of a preventive resource in work involving a risk of falling from heights that the assessment classifies as being of special risk.

Limits and common mistakes

1. Assuming that there is no work at height below two meters and not assessing the risk of falling on low platforms, stairs and docks.
2. Using a harness as a first measure, without considering platforms or railings, or using it without a suitable anchor point or sufficient free distance.
3. Use ladders as a workstation for long or strenuous tasks, rather than as a means of access.
4. Working without a rescue plan; prolonged suspension in a harness causes serious damage in a few minutes.
5. Erecting scaffolding without an assembly plan, without trained personnel, and without prior inspection.
6. Forget about occasional maintenance, cleaning and installation work on roofs, which account for a significant portion of fatal falls, often through fragile materials.

Regulatory framework in Spain

• Royal Decree 1215/1997, Annex II, Section 4 (introduced by Royal Decree 2177/2004) . Provisions relating to the use of work equipment for carrying out temporary work at height: ladders, scaffolding and rope access techniques.
• Royal Decree 486/1997, Annex I. Protection of openings, levels and platforms with a risk of falling from more than two meters; railing requirements.
• Royal Decree 1627/1997, Annex IV . Minimum health and safety provisions in construction works, including protection against falls from height.
• Royal Decree 773/1997 . Use of personal protective equipment, including fall protection systems.
• Law 31/1995, articles 15, 16 and 32 bis . Principles of preventive action, evaluation and presence of preventive resources in activities with risk of falling from height classified as of special risk.

Directive 2001/45/EC, which amended Directive 89/655/EEC, is the European origin of Royal Decree 2177/2004. The UNE-EN standards for fall protection equipment (EN 361, EN 354, EN 355, EN 360, EN 795 series) and scaffolding (EN 12810 and EN 12811) define the technical requirements for the equipment.
