Fall Arrest Systems
Fall Arrest Systems are essentially a collection of safety equipment conforming to the required standards, used in conjunction with each other to ensure the safety of a worker whilst working at height. A simple way of remembering the core components of a fall arrest system is the ABCD of Fall Arrest.

Anchorage - A secure point of attachment (structure) for the fall arrest system

Body Harness - Full body harnesses provide a connection point on the worker for the personal fall arrest system

Connectors - Devices used to connect the worker’s full body harness to the anchorage system. (e.g. shock absorbing lanyard, retractable fall arresters, etc.)

Descent and Rescue - Always required, the need for adequate rescue plans, training and equipment is vital in every work at height situation

Anchorage
An anchorage is a secure point of attachment for the fall arrest system. The anchorage must be capable of supporting the load of a fallen worker, (12kN) Anchorages may be certified (designed or engineered on site for fall protection) or non-certified (beams, trusses or other suitably strong structures).

Body Harnesses
A full body harness is designed to fasten around the user in order to distribute fall arrest forces over at least the upper thighs, pelvis, chest and shoulders, moving the impact of a fall from the internal organs to the major bone and muscle groups around the pelvis. Fall arrest harnesses provide a vital link between the user and the safety system, the fall arrest harness is a fundamental component of working at height methods. A fall arrest harness should offer comfort and freedom of movement to the worker, as well as good safety characteristics. Harnesses are chosen according to the task they must perform, hence the various types of harness.

Connectors
Fall protection lanyards are flexible lines with a connector at each end, used to join the anchorage to the body support. Lanyards should be connected to the back D-ring for fall arrest and ideally should be anchored above the worker to minimise fall distance. Lanyards designed for use as part of a personal fall arrest system must contain an energy absorbing unit that will limit the force on the worker to below 6kN. A lanyard should be long enough to be user-friendly, (standard length is 2m) but kept as short as possible to minimise the free fall distance.

Fall restraint lanyards do not contain absorbing devices and are used to restrain the user from leaving a safety zone, eliminating the risk of a potential fall.

Self-Retracting Lifelines are flexible lifelines attached to a mechanism that allows it to extend and retract under slight tension when the user moves away from and toward the device, ideally anchored to a location directly above the user. SRLs can also be used with a horizontal lifeline.

Descent and Rescue
Legislation stipulates that all workers who perform their task in an area where a fall risk is present are both provided with equipment to minimise or negate the risk, and are also trained in its use and inspection. Training should also cover the need for and the details required in a rescue plan. The correct and accurate selection of Fall Arrest & Rescue Equipment is vital, as the incorrect equipment can not only place the injured person at more risk, but can also mean that the rescuing party is themselves placed in an area of heightened risk of a fall. In-depth training in the use of any fall arrest harness and fall arrest PPE equipment is absolutely essential.



Training
It is essential any persons intending to use fall protection and arrest harnesses to be aware of the risks involved in working at height, understand the risks from incorrect use and are suitably trained in its correct use and maintenance.

Inspection & Maintenance
It is vitally important Fall Arrest Harnesses and Fall Protection Equipment be inspected on a regular basis. A visual inspection must be undertaken before each use, and an annual inspection is to be made by a qualified inspector according to EN 365:2004. Any inspection should include a visual inspection of ropes, cables, straps etc. A manual check of locks, housing screws, adjusting devices, carabineers, fall arresters and manual rope grabs etc. Further, all inspections need to be made in accordance with any manufacturer´s instructions.

Fall Protection Equipment - Important Considerations
Because components for fall protection systems, and support equipment are often sold as separate products, it is very important to make sure that all components to be included in the system are compatible with one another to ensure the intended system will provide the required protection.

Before using fall arrest harnesses and belts in the field, all equipment should be tried on to ensure a correct fit which doesn't hinder the user. The user’s guide will provide information about how to correctly wear a harness or belt and how one then connects it to the rest of the protection system.

In the event fall protection equipment has been subjected to a fall or other potentially harmful stress it should be removed from use for service or discarded all together.

Fall protection equipment must be cleaned according to the manufacturers’ instructions, and should be stored in a dry, dark and well ventilated place.

If you are uncertain about your equipment´s functionality, or if it has been exposed to abnormal stress, don´t use it!

Manual Rope Grab
When undertaking work on ladders, or masts, etc., it may be advisable to use rope grab system whereby it follows the climber when either ascending or descending and automatically locks in the event of a fall. Standard EN 353-1.

Where horizontal as well as vertical movement is necessary, it may be suitable to use a system incorporating a flexible climbing line, an automatically-locking manual rope grab and a connecting line between the rope grab and the users harness.

Support Equipment
Fall protection equipment and harnesses providing support during work while preventing a fall. Common applications include working on electrical poles, window cleaning, or working on flat roofs, ledges or catwalks.
Support equipment systems generally consist of a support belt or sitting harness (EN 813), as well as a connecting line. (EN 358). The support belt can also be a part of a full body harness.
