What does a Fall Arrest Block do?

In the event of a fall the braking mechanism on the drum holding the rope or webbing (that is attached to the users harness) is engaged and arrests the fall.

All self-retracting fall arrest blocks are designed for use in vertical / near vertical applications, & some have also been tested and approved for use in other applications, for example horizontally (such as a fall off a flat roof) where the classification / type of edge is also detailed (for example a smooth edge as small as 0.5mm radius).

Always check with manufacturers recommendations for that specific make and model of equipment, as some equipment requires additional special equipment to be used in conjunction with the fall arrest block. The maximum user mass capacity of a fall arrest block can also vary with the application of use.

Some other self-retracting fall arrest blocks have also been tested & approved for use in other very specialist applications these include: –

  • A self-retracting fall arrest block that comes with an integral rescue recovery winch facility. This style of equipment will also have been tested against the European Standard EN1496 (Personal fall protection equipment. Rescue lifting devices, 1996 later superseded in 2006) whereupon the user can be raised / lowered in an emergency by a rescuer. Ideal for use in many confined space applications.
  • A self-retracting fall arrest block that comes with an integral auto-descent descender facility. Features from manufacturer’s can vary, e.g. on some the auto-descent function engages automatically, on others it must be manually engaged, or can be set accordingly prior to use depending on the intended application. This style of device will also be tested against the European Standard EN341 – Personal fall protective equipment – Descender devices for rescue. 1992 later superseded in 2011.

Fall arrest blocks are available with a very wide variety of materials and other features not detailed above, for example: – with webbing, galvanised wire, stainless steel wire; composite / metal casings; sealed units for use in very harsh environments; some require a service at specialist service centres; different maximum user capacities in certain modes of use etc.
