What you need to know about roof lifeline and NR 35

linha de vida para telhado + NR 35

The roof lifeline is an essential mechanism to prevent the risk of falling when working at height. No wonder there is a specific standard to regulate this type of work, the NR 35. In this content, we will explain this regulation and show how to adapt to the legislation, setting up a safe construction site and preserving the integrity of employees. Check it out!

What is a roof lifeline?

The roof lifeline is a system formed by a highly resistant cable. This cabling is fixed to the roof of the building by means of anchor points, which may be configured in various ways, depending on the type of roof.The purpose of the lifeline is to ensure that the employee is always connected to a safe point. The goal of the lifeline is to ensure that the employee is always connected to a safe point, so that he or she can move smoothly on the roof while performing the necessary tasks, without worrying about the risk of falling or other accidents.

What is its importance and what is it used for?

It has been established that the lifeline is a mandatory item in any activity performed at height, such as scaffolding, ladders, or roofs. This resource is extremely important not only because it keeps the employee safe, but also because it allows free movement around the site. This is essential for the proper performance of services.

One example is cleaning and maintenance work on roof structures, such as daylight domes. The lifeline is necessary to avoid the risk of falling and at the same time contribute to the good result of the service. In the case of domes, proper maintenance helps ensure the high performance of this sustainable system, enabling the effective and strategic transmission of sunlight.

As for the roof lifeline, it is also worth remembering that this resource alone is not enough to guarantee safety. The other Personal Protective Equipment (PPE) must be used by employees during the entire course of the work at height.

What is the difference between lifeline and anchor point?

Since working at height does not allow the implementation of physical barriers to prevent falls and accidents, the roof lifeline has become an indispensable item on these occasions. This type of steel cable installation is connected to the employee's safety belt and anchor points, thus enabling total safety when performing the work.

The difference between the lifeline and the anchor points is that these points are the places where the protection system will be fixed, i.e. on the structure of the building. However, it is necessary to pay close attention to the location of these points, which must be strategically positioned in places of greatest risk of falling.

It is also essential that the employees who are going to use the resource are well trained and fully aware of the site configuration.

What does NR 35 say about the roof lifeline?

NR 35 is the ABNT Standard that regulates working at height. According to the Standard, work at height is considered to be any activity performed above two meters, which poses a risk of falling.

As for anchor points, they must be sized in advance and determined by a legally qualified professional. This is what will ensure safety in the use of the roof lifeline.

In summary, these are the aspects defined by NR 35:

  • Prior evaluation of the integrity of the system and anchor points;
  • Certification of the system's strength to withstand the maximum load;
  • Selection of legally qualified professionals to size the system.

What are the differentials of the MB Group's Roof Lifeline project?

The MB Group is a reference company in manufacturing, sizing and maintenance of intelligent systems for the industry. The lighting and natural ventilation solutions from the MB Group represent the most innovative in terms of industrial sustainability, bringing thermal comfort, energy savings, and quality of life to the workplace.

Aware of the importance of keeping its employees safe, the MB Group created the Roof Lifeline project. The system ensures the safety of workers through the use of high-strength cables, fixed to the work or the building by means of anchoring. This solution allows employees to move freely on top of the building, reducing the risk of falling and ensuring compliance with legislation.
