When working at height, safety is paramount. We know that mastering how to fasten a safety harness can mean the difference between a successful job and a serious accident. In this article, we will guide you through the essential steps to secure your harness effectively and safely.

Importance of safety when working at height

When working at height, every precaution counts. The slightest negligence can lead to serious or even fatal consequences. This is why it is important to emphasize the importance of security and the adoption of safe and regulated practices.

Falls from height represent a significant proportion of workplace accidents, particularly in the construction and maintenance sector. According to data collected by occupational risk prevention organizations, falls are responsible for nearly 30% of deaths in the construction industry. These alarming statistics aren't just numbers; they represent lives, often those of experienced people who had a moment of inattention or a flaw in their safety equipment. This observation reinforces the urgency of adopting strict preventive measures and ensuring constant vigilance on construction sites.

The regulations in force are designed to minimize risks and protect the lives of workers. In Europe, for example, Directive 89/655/EEC states that employers must provide suitable work equipment and ensure that it is maintained in good condition. In France, the Labor Code also requires the use of personal protective equipment (PPE) adapted to the risks encountered, in particular safety harness for working at height. Complying with these standards is not only a legal obligation; it is an ethical responsibility that all those involved in construction must take seriously. As site managers, we must ensure that these standards are rigorously applied and that each member of the team is trained to work safely.

What is a safety harness?

A safety harness is essential personal protective equipment (PPE) for work at height, where the risk of falling is significant. It is a device designed to secure a person to an anchor point, thereby reducing the risk of free fall and minimizing the consequences in the event of an incident.

A typical safety harness is made up of several fundamental elements that work together to provide safety and support. The straps, made from durable materials such as nylon or polyester, form the basic structure of the harness and are designed to distribute impact forces evenly across the body in the event of a fall . The adjustment buckles allow for a personalized fit, ensuring that the harness fits the user comfortably without compromising mobility or safety. The attachment points, generally located at the front and back of the harness, serve as connections for carabiners, ropes or lifelines, and must be strong to withstand the forces extremes in the event of a fall.

There are different types of harnesses designed specifically for various applications, each suited to specific environments and risks. For example, a basic harness may be sufficient for less complex work at height, while a harness with a positioning belt is better suited for work requiring freedom of movement. larger movement, such as painting or installing structures. For situations where workers need to be precisely positioned while still being secure, such as during rope access, a full body harness with side attachment points is ideal. Choosing the right type of harness not only improves the user's safety, but also increases their efficiency and comfort during work.

Choosing the right harness

Choosing the right harness is a critical decision to ensure safety when working at height. Every detail counts, because inappropriate equipment can increase the risk of serious accidents. We will explore the essential criteria to consider when selecting a harness that not only meets safety standards but also provides comfort and protection to the user.

The first step in choosing a harness is to ensure that it fits the user perfectly. A properly fitted harness should be comfortable while allowing a full range of movement without compromising safety. The straps should neither be too tight, which could hinder circulation and movement, nor be too loose, which could increase the risk of slipping or poor distribution of forces in the event of a fall. It is essential to follow the manufacturer's instructions to adjust each strap to precisely fit the user's body shape. Some harnesses offer additional adjustment options that can help achieve an even more precise fit, suitable for various body types and work clothing.

The load capacity of the harness is also an important factor. Each harness is designed to support a specific weight, including not only the weight of the user but also that of any equipment worn. It is vital to choose a harness with a load capacity appropriate to the working conditions. In addition, the harness anchor points must be robust and capable of withstanding the forces generated during a fall. They must be positioned to optimize the distribution of forces and minimize the risk of injury when stopping a fall. These points must be compatible with other components of the safety system used, such as ropes and carabiners, to ensure seamless systemic integrity.

Checking equipment before use

Checking safety equipment before each use is a necessary step to ensure safety when working at height. This practice makes it possible to detect in time any signs of wear or damage that could compromise the functionality of the harness and, therefore, the safety of the user.

A careful visual inspection of the harness must be carried out before starting any work at height. This inspection should cover all components of the harness, including straps, buckles, anchor points, and any other hardware such as carabiners and connectors. Actively look for signs of wear such as frayed threads, cuts or scrapes on straps, deformation of metal buckles, and cracks or corrosion on metal parts. Often subtle failures can have dramatic consequences, so each anomaly must be taken seriously and evaluated by a professional if necessary.

Harnesses used for roof work must not only be robust but also specifically adapted to the roof conditions. This means they must be designed to withstand environmental factors such as extreme temperature variations, exposure to sunlight, and potentially abrasive surfaces. In addition, given the frequent and sometimes rapid movements on roofs, the harness must allow good mobility while remaining correctly positioned on the user's body. For these reasons, it is imperative to choose a harness with anchor points that can be easily and safely attached to lifelines or other anchoring systems specific to roofing work.

Examination of these specific aspects not only ensures the safety of the user but also contributes to the efficiency and speed of execution of the work, thus reducing the risks linked to prolonged exposure at height. A well-maintained harness suited to the specific work environment is essential to ensuring overall safety on the job site.

Installing the safety harness

Correctly installing a safety harness is fundamental to guarantee effective protection of the user when working at height. This procedure must be carried out with care and attention, following precise steps to ensure that the harness is not only properly fitted, but also correctly attached to the anchorage system. Proper installation helps prevent accidents and increases user confidence when working at high heights.

Before you begin installing your harness, it is essential to gather all the necessary tools and equipment. This can include the harness itself, a lanyard, carabiners, a lifeline, and any other elements specific to your safety system. Make sure these tools are in good condition and appropriate for the type of work you will be doing. It is also important to have a clear and safe work space to facilitate access to all harness components and enable unhindered installation.

Preparation for working at height is not limited to technical and material aspects; it also includes physical and mental preparation. Physically, make sure you are in good condition to support the weight of the harness and the potential stress of a fall. Warming up and stretching exercises before starting work can help prevent muscle and joint injuries. Mentally, it is important to be fully aware of the risks involved and to concentrate fully on the tasks at hand. Mental preparation may include reviewing safety procedures, visualizing the steps of harness installation, and reviewing emergency protocols, which can greatly reduce stress and increase efficiency when handling equipment in height.
