Working at height remains one of the most significant risks in construction, with falls being a leading cause of serious injury and fatalities. As a result, stringent safety measures and the correct use of fall protection equipment are crucial. Two key systems used to protect workers are fall restraint and fall arrest systems. While they may seem similar, they serve very different purposes. Understanding these differences ensures that the right equipment is used for the right application, keeping workers safe and compliant with health and safety regulations.
What is a Fall Restraint System?
A fall restraint system is designed to prevent a worker from reaching a fall hazard in the first place. This system restricts movement by limiting how far a worker can travel, ensuring they remain within a safe working area.
Key Features of Fall Restraint Systems:
-
Uses a harness and lanyard to keep workers away from edges.
-
The lanyard length is adjusted to prevent the worker from reaching a point where a fall could occur.
-
Ideal for flat roofs, scaffolding, and elevated platforms where work is required near an edge.
-
Helps eliminate the risk of a fall rather than mitigating its consequences.
When to Use Fall Restraint:
-
When work can be carried out at a safe distance from an unprotected edge.
-
When collective protection measures (such as guardrails) are not practical.
-
In areas where fall arrest systems are unnecessary or impractical due to space constraints.
What is a Fall Arrest System?
A fall arrest system is designed to catch a worker in the event of a fall, preventing them from hitting the ground or another hazard below. Unlike fall restraint, which prevents falls altogether, fall arrest systems assume that a fall may occur and provide a controlled stop to minimise injury.
Key Features of Fall Arrest Systems:
-
Consists of a full-body harness, shock-absorbing lanyard, and anchor point.
-
Allows workers to access areas where a fall hazard exists.
-
The shock-absorbing lanyard or self-retracting lifeline reduces impact forces on the body.
-
May require additional rescue planning, as a fallen worker could be left suspended.
When to Use Fall Arrest:
-
When workers must operate near or beyond the edge of a fall hazard.
-
When working at height without physical barriers, such as open frameworks or high-rise construction projects.
-
In situations where fall restraint is not feasible, such as roof work with limited anchor points.
UK Regulations and Compliance
In the UK, working at height is regulated by the Work at Height Regulations 2005, which mandate that employers must prioritise fall prevention before fall protection. This means that fall restraint systems should be considered before fall arrest systems whenever possible.
Employers must also:
-
Conduct risk assessments to determine the most appropriate fall protection system.
-
Ensure workers are trained in using fall restraint and fall arrest equipment correctly.
-
Provide inspection and maintenance of all safety equipment in accordance with manufacturer guidelines and legal requirements.
Choosing the Right System for Your Site
Selecting the right system depends on the nature of the task, worksite conditions, and regulatory requirements. Here are some questions to help guide your choice:
-
Can the task be completed without reaching a fall hazard? → Use fall restraint.
-
Is there no way to avoid working in a hazardous area? → Use fall arrest.
-
Are suitable anchor points available? → Ensure your chosen system can be securely attached.
-
Is rescue planning in place for a fall arrest scenario? → If not, a fall restraint system may be safer.
