Work carried out at height, such as on roofs, scaffolding and elevated structures, presents significant risks. Regulatory Standard No. 35 (NR 35) establishes guidelines to protect workers in these situations, and one of the most effective systems is the lifeline.
Next, we will address the importance of the lifeline, how it contributes to safety at height and how its implementation must follow NR 35.
What is a Lifeline
The lifeline is a collective protection system made up of steel cables or other materials, connected to anchor points. These points allow the worker's safety belt to be secured, preventing falls when moving in high places, such as roofs.
Lifeline Components
- Hot-dip galvanized steel cable;
- Anchor point within 15 meters;
- Stretcher only at the ends;
- Clamps, shoes at all splice points or ends/starts of the system;
- Impact absorber at the ends;
- Sealing at all anchor points;
Types of Lifeline
1. Temporary Lifeline
Ideal for temporary applications, such as civil construction or industrial maintenance. It can be horizontal or vertical:
- Horizontal: composed of ribbons or cables that allow lateral movement.
- Vertical: includes ropes or rails with fall arresters for upward and downward movement.
2. Fixed Lifeline
Designed for continuous use in places such as roofs and warehouses.
- Fixed horizontal: for linear displacement in specific locations.
- Fixed vertical: commonly used on metal stairs or towers.
When it is necessary to use the Lifeline
According to NR 35, the lifeline must be used in any activity carried out above 2 meters from the lower level, where there is a risk of falling. Application examples:
- Roof maintenance.
- Work on scaffolding and ladders.
- Installation of electrical systems on poles or towers.
- Cleaning of industrial structures.
How to implement a Lifeline and ensure safety at height and compliance with NR 35
1. Diagnosis and technical design
- Assessment of the environment and the risks involved.
- Sizing of the lifeline in accordance with the standards of NR 35 and ABNT NBR 14606.
2. Installation and fixing
- Strategically positioned anchor points, respecting the integrity of the structure (e.g.: fixing without drilling in zipped tiles).
- Safe connection of cables with turnbuckles and impact absorbers.
3. Testing and certification
- Carrying out load tests to check the resistance of the structure.
- System certification, ensuring compliance with current standards.
4. Employee Training
- Training on the correct use of the lifeline and other PPE.
- Emergency simulations and risk analysis.
Lifeline inspection and maintenance
The lifeline must be inspected regularly as its effectiveness depends on preventive maintenance. Key times for inspection include:
- Before first use.
- After significant changes or impacts.
- Periodically, every 12 months.
During the inspection, it is verified:
- Integrity of cables and anchor points.
- Presence of corrosion or wear.
- Compliance with safety standards.
Compliance with NR 35
NR 35 establishes essential requirements to ensure safety when working at height. Because of this, prior risk analysis is essential, as it evaluates environmental conditions and identifies possible dangers before activities begin.
Furthermore, the standard determines the mandatory use of Collective Protection Equipment (EPCs) and Personal Protective Equipment (PPE), such as seat belts equipped with energy absorbers, to minimize impacts in the event of falls.
Another fundamental point is the need for supervision by qualified professionals, as this ensures that operations are carried out safely and in accordance with standards. Finally, NR 35 requires that the Fall Protection System (SPCQ) undergo periodic inspections and certifications, ensuring that all components are in suitable conditions for use.
Why invest in Lifeline
Investing in a lifeline goes beyond meeting a legal requirement, as it is a fundamental step to guarantee the safety of workers at height. The implementation of this system significantly reduces the risk of fatal accidents, providing effective protection during activities. Furthermore, the lifeline allows professionals greater freedom of movement, without compromising their safety, which also contributes to work efficiency.

In short, complying with this requirement ensures the protection of employees and avoids fines and sanctions that could result from non-compliance with these regulations.
Conclusion
The lifeline is an essential element when working at height. Its proper implementation, following the guidelines of NR 35, protects employees and guarantees safety in any project.
