Work carried out at height, such as on ceilings, scaffolding and elevated structures, presents significant risks. Regulatory Standard N° 35 (NR 35) establishes guidelines to protect workers in these situations, and one of the most effective systems is the line of life.
Next, we will address the importance of the life line, how it contributes to safety at height and how its implementation must comply with NR 35.
What is a Line of Life
The life line is a collective protection system made up of steel cables or other materials, connected to anchor points. These points allow the worker's safety harness to be secured, preventing falls during movement in elevated places, such as roofs.
Components of the Line of Life
- Fireproof galvanized steel cable.
- Anchorage points every 15 meters.
- Tensioner at the ends.
- Braces and shoes at all points of connection or the beginning/end of the system.
- Impact absorber at the ends.
- Sealed at all anchor points.
Types of Lifeline
- Temporal Life Line
Ideal for temporary applications, such as civil construction or industrial maintenance. It could be:- Horizontal: Made up of straps or cables that allow lateral movement.
- Vertical: Includes anti-fall chains or rails for upward and downward movements.
- Fixed Life Line
Designed for continuous use in places such as industrial buildings and warehouses.- Fixed horizontal: For linear layouts in specific places.
- Fixed vertical: Commonly used on metal steps or towers.
When should you use Línea de Vida
According to NR 35, the life line must be used in any activity carried out more than 2 meters from the lower level where there is a risk of falling. Some examples of applications:
- Tech maintenance.
- Works on scaffolds and ladders.
- Installation of electrical systems on poles or towers.
- Cleaning of industrial structures.
Implementation of a Lifeline in accordance with NR 35
- Diagnosis and Technical Project
- Assessment of the surroundings and the risks involved.
- Dimensioning of the life line according to NR 35 and ABNT NBR 14606.
- Installation and fixing
- Anchor points strategically positioned, respecting the integrity of the structure (for example, fixing without perforations in zipped sections).
- Safe connection of cables with tensioners and impact absorbers.
- Testing and Certification
- Carrying out load tests to check the resistance of the structure.
- System certification to ensure compliance with current standards.
- Training of Employees
- Training on the correct use of the line of life and other personal protective equipment (PPE).
- Emergency drills and risk analysis.
Inspection and Maintenance of the Line of Life
Therelife lineIt must be inspected regularly to guarantee its effectiveness. Main moments for inspection:
- Before first use.
- After modifications or significant 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 guarantee safety when working at height, including:
- Carrying out a previous risk analysis to evaluate the surrounding conditions.
- Mandatory use of Collective Protection Equipment (EPCs) and Individual Protection Equipment (EPIs), such as harnesses with energy absorbers.
- Supervision by trained professionals.
- Periodic inspections and certifications of the Fall Protection System (SPCQ).
Why invest in Línea de Vida
Investing in a way of life will also have to comply with a legal requirement: it is a crucial step to guarantee the safety of workers at height. This system significantly reduces the risk of fatal accidents and provides effective protection during activities.
Complying with this requirement on the ground ensures the protection of employees, but also avoids fines and sanctions for non-compliance with regulations.
Conclusion
The life line is an indispensable element for working at heights. Its adequate implementation, complying with NR 35, protects employees and ensures safety in any project.
