When Is It Mandatory to Wear a Safety Harness?


The use of a safety harness is a fundamental measure in working at heights and activities with fall risks. However, many workers and employers are unaware of when its use is mandatory and which regulations govern it. In this article, we will address this question with technical and regulatory information to ensure safe operations.

Regulations governing the use of safety Harnesses

Laws and regulations vary by country, but internationally, some key standards include:

OSHA (Occupational Safety and Health Administration - USA): Requires the use of a harness when working above 1.8 meters (6 feet) without collective protections.

EN 361 Standard (Europe): Regulates safety harnesses for work at heights and their certifications.

ANSI Z359.1 Standard (USA): Establishes requirements for personal fall arrest systems.

Local regulations: Each country has its specific legislation, such as Decree 594 in Chile or Resolution 1409 in Colombia.

Situations Where Wearing a Harness Is Mandatory


1. Work at Heights (+1.8 Meters)

Any task performed at more than 1.8 meters above ground without collective protections (railings, enclosed platforms, or safety nets) requires a safety harness with a lifeline system.

2. Work on Scaffolding and Metal Structures

While some scaffolding has safety railings, in many cases, wearing a harness is mandatory to prevent falls in high-risk areas.

3. Operations with Overhead Cranes and Rigging

Riggers and overhead crane operators must wear harnesses when working on elevated structures or directing lifting maneuvers in hazardous zones.

4. Work on Poles and Telecommunications Towers

Electricians and telecom technicians must use harnesses with fall-arrest systems to ensure their safety while working at extreme heights.

5. Confined Spaces

In confined spaces with fall or rescue risks, using a harness with a lifeline is essential to ensure worker safety.

6. Work on Roofs and Sloped Surfaces

When there are no perimeter protections, it is mandatory to use a harness with an anchoring system to prevent slips or falls.

7. Activities on Tower Cranes or Freight Elevators

Operators required to climb cranes or perform maintenance on elevated structures must wear a fall protection system.

Essential Components of a Personal Fall Protection System

For the harness to function correctly, it must be complemented by:

• Certified anchorage points with adequate resistance.

• Vertical or horizontal lifelines.

• Shock absorbers to reduce the force transmitted in case of a fall.

• Certified connectors and carabiners.

• Periodic equipment inspections to ensure optimal condition.

Conclusion

Wearing a safety harness is not just a legal requirement in many situations—it is also a crucial measure to protect workers' lives. Proper use, combined with other safety elements, minimizes risks and ensures a safe working environment. Always check local regulations and ensure your equipment meets the appropriate standards.
