Building and maintaining wind farms requires work at great heights, which makes safety a crucial factor for workers. The correct use of specific personal protective equipment (PPE) for work at height is therefore vital to prevent serious accidents and ensure safety. This article presents the main work at height equipment used in this sector and the benefits of a document management platform for controlling PPE inspection, expiry dates and distribution.
Challenges and risks of work at height
Wind farms present challenging conditions for maintenance technicians. Wind turbines can exceed 100 metres in height, exposing workers to:
Fall risks: The leading cause of fatal accidents in work at height.
Adverse weather conditions: Strong winds and sudden changes in weather.
Physical fatigue: Caused by long shifts and poor ergonomic postures.
Adopting suitable PPE and implementing safe practices are essential to mitigate these risks.
Main protective equipment for work at height
PPE designed for work at height plays an essential role in protecting workers. Among the most widely used in the wind sector are:
Safety harness
Supports the worker’s body and connects to a fall arrest system.
Correct adjustment is essential to ensure maximum effectiveness.
There are also specific models for suspended work, with additional support.
Helmet with chin strap
Protects against impacts and falling objects. In addition, the chin strap prevents the helmet from falling off during work at height.
Lifelines and fall arresters
These anchor the worker and allow them to move around safely. The fall arrester locks automatically in the event of a fall.
They can be horizontal or vertical, depending on the anchorage structure.
Karabiners and anchor slings
These connect fall arrest systems to anchor points. They must therefore be made of high-strength materials and certified to the applicable European standards.
Safety boots
Essential to prevent slips on sloping or wet surfaces.
They must be certified to EN ISO 20345.
Lumbar belts and suspension systems
These provide additional support during prolonged tasks to reduce fatigue.
Protective gloves
Protect hands against abrasion and cuts during maintenance work.
The choice should depend on the type of work, and gloves must be certified to EN 388.
Inspection and maintenance of work at height equipment
The effectiveness of PPE depends on proper maintenance and regular inspections. However, a lack of periodic inspections can lead to equipment failures with fatal consequences. For this reason, recommended practices include:
Daily visual inspections: Check for visible damage before each use.
Periodic inspections by a competent person: Follow the manufacturer’s recommendations.
Records of inspections and replacements: Document all inspections and corrective actions.
Benefits of document management platforms for work at height equipment
Effective management of PPE for work at height is fundamental to ensure its compliance and effectiveness. Document management platforms offer effective solutions for this purpose.
Monitoring inspections and expiry dates
Equipment such as harnesses and lifelines must undergo periodic inspections. A platform therefore makes it possible to schedule automatic reminders for inspections and replacements based on expiry dates.
Centralised inventory management
The platform makes it possible to catalogue all equipment, with the purchase date, the inspections carried out and their results. In this way, a complete and transparent history is available.
PPE distribution and assignment
The system makes it possible to track the equipment assigned to each worker, ensuring that every professional uses suitable PPE in good condition.
Compliance with safety standards
A platform helps demonstrate compliance with legal and regulatory requirements and, consequently, avoid fines and other penalties.
Automated reports and audits
The platform automatically generates reports on the status of PPE, making safety audits easier.
Integration with identification technologies
The most advanced solutions integrate RFID tags or QR codes into PPE, which allows inspections to be recorded on mobile devices and simplifies updating records.
Safety and efficiency in the wind sector
Working on wind turbines exposes technicians to specific risks, including strong winds and considerable heights. Combining suitable PPE with digital document management therefore significantly strengthens safety and makes work more efficient.
By adopting a document management platform for PPE management, wind energy companies strengthen their commitment to safety, optimise processes and ensure compliance. In short, investing in technology and prevention is the foundation of a safer and more sustainable wind sector.
Standards applicable to fall protection equipment
Fall protection equipment is category III PPE under Regulation (EU) 2016/425, because it protects against risks that can cause death. It must therefore bear the CE marking and come with an EU declaration of conformity and the manufacturer’s instructions in the user’s language. In addition, each component follows its own European standards:
| Equipment | Reference standard |
|---|---|
| Fall arrest harness | EN 361 |
| Guided type fall arresters on a rigid or flexible anchor line | EN 353-1 and EN 353-2 |
| Energy absorbers and lanyards | EN 355 and EN 354 |
| Connectors and karabiners | EN 362 |
| Anchor devices | EN 795 |
| Helmet for work at height | EN 12492 or EN 397 with chin strap |
In Portugal, the use of PPE by workers is regulated by Decree-Law No. 348/93 and Ministerial Order No. 988/93. In turn, EN 365 establishes that fall protection equipment must be inspected by a competent person at least every 12 months, and whenever the manufacturer specifies.
Training and rescue plan
However, equipment does not protect those who do not know how to use it. For this reason, in the wind sector, training for work at height normally follows the Global Wind Organisation standard, with the Working at Heights module, which must be renewed every two years. In addition, every job at height needs a rescue plan. Indeed, a worker suspended in a harness can suffer what is known as suspension trauma within minutes. The team must therefore have the means and training to rescue them quickly, without relying solely on the fire service, which may take time to reach an isolated wind turbine.
Practical example: A maintenance team on a wind farm
Consider a team of four technicians about to carry out maintenance on a turbine. Before leaving, the supervisor checks the platform and confirms that everyone has valid GWO training and medical fitness. Next, they verify that the harnesses, fall arresters and rescue kits assigned to the team have an up-to-date annual inspection. Then, on site, each technician carries out a visual inspection before use and records it on their phone via the equipment’s QR code. Finally, if a piece of equipment is defective, the platform marks it as out of service and prevents it from being assigned.
The role of the document management platform
On a wind farm, technicians often come from subcontracted companies and frequently change location. The platform should therefore bring together, in one place, each technician’s training, medical fitness, assigned PPE and the inspection status of each piece of equipment. In this way, the safety manager knows before each job whether the team and the equipment are fit for work. In addition, records are available for audits by the client, the insurer or the ACT, the Portuguese labour inspectorate.
Work at height checklist
- PPE with CE marking and EU declaration of conformity.
- Periodic inspection by a competent person, at least annually.
- Visual inspection before each use.
- Valid work at height training.
- Rescue plan and kit available on site.
- Record of PPE assigned to each worker.
Common mistakes to avoid
A frequent mistake is to keep using a harness or fall arrester after a fall, when the manufacturer requires it to be withdrawn from service. Another mistake is to combine incompatible components from different manufacturers. Moreover, many teams have no rescue plan, assuming that external emergency services will arrive in time.
Frequently asked questions
How often should harnesses be inspected?
Before each use, through a visual inspection, and at least once a year by a competent person, in accordance with EN 365 and the manufacturer’s instructions.
Does fall protection PPE have an expiry date?
Many manufacturers specify a maximum service life, especially for textile components. However, the condition of the equipment and the inspections determine whether it can remain in use.
Conclusion on work at height equipment
Safety on wind farms requires more than the use of PPE: it calls for an integrated approach, with constant monitoring, efficient document management and regulatory compliance. Document management platforms are essential tools for achieving these goals, offering a robust and scalable solution that protects lives and improves productivity.
