Fall arrest vs fall restraint: What is the difference?
If you can’t avoid working at height or if collective solutions (such as barriers or guardrails) are unsuitable, then a Personal Fall Protection System (PFPS) is your best bet.
Both Fall Restraint and Fall Arrest systems are Personal Fall Protection Systems and they must be designed to a Fall Arrest standard.
These systems include horizontal lifelines, fixed anchor points or portable anchor points.
FALL RESTRAINT
What is Fall Restraint?
Fall Restraint systems prevent you from falling.
They use a body holding device connected to a reliable anchor, preventing you from reaching zones where the risk of fall exists.
Fall restraint is sometimes referred to as ‘Restraint’ or a ‘Work Restraint’ system.
When should you use it?
In the hierarchy of controls, Restraint is preferred to Fall Arrest.
Sometimes, due to restricted free fall distances (e.g. low building height, vehicles, racking or machinery in or around the building reducing available height to have the fall arrested safely), a Restraint system would be the only choice.
Typically, a Restraint system is simpler to use than a Fall Arrest system and is therefore more likely to be used.
Compared to a Fall Arrest system, Fall Restraint does not require a rescue plan.
FALL ARREST
What is a fall arrest system?
Fall Arrest systems protect you after you fall: they stop the fall before you hit the surface.
These systems use a body holding device connected to a reliable anchor; they arrest and restrict a fall preventing you from colliding with the ground or structures, whilst limiting the forces on the body.
When should you use it?
When you are working near a fragile surface, narrow ledge or unusual building or roof shape and are using lanyards or a rope, there is a good chance you might fall off or into the building.
This is when you need a Fall Arrest system, together with personal protective equipment (PPE). You also need additional training and, by law, you are required to have a rescue plan in place. This means that you can be retrieved as soon as possible should you fall.
