Personal Protection Equipment

10. Classification of PPE

10.8. Fall-arrest protection

ISASTUR Group in-house regulations with respect to the risk of falling to a different level indicates that “above 1.5 metres of height, workers must be provided with collective or individual protection”.

Evidently, the risk of falling to a different level may be very serious, and which, should it occur, may cause a mortal or serious accident for the worker.

IMPEDE THE FALL By eliminating hazards
By using collective protection
LIMIT THE FALL By placing protection nets
PERSONAL PROTECTION Using fall-arrest devices

When faced with the risk of falling to a different level, action should be taken in the following order:

Fall-arrest PPE is understood as equipment that fastens the person to an anchor point and which avoids any fall from a height or detains such a fall under safety conditions.

This type of equipment is classified as follows:

  • Systems for fastening in a working position.
  • Fall-arrest systems.

Systems for fastening in a working position:the aim of these is to sustain the worker at a height. They should not be used for stopping the fall and must always be simultaneously used with a fall-arrest system, which should be inactive.
Fall-arrest systems: the set of PPE that allows the fall to be arrested under safety conditions, composed of a fall-arrest harness plus one of the three elements or devices indicated below which would be used to connect the user to a safe anchor point.

FALL-ARREST SYSTEMS Fall-arrest harness
Fastening elements with an energy absorber
Sliding fall-arrest devices compatible with a rigid or flexible anchor line
Fall-arrest devices with automatic or retractile retention

Fall-arrest harness:
This is a device worn on the body aimed at arresting falls. It may be made up of strips, fitting elements, buckles and other elements, suitably placed and fitted  around a person’s body to sustain him during a fall and after the fall has been arrested.

Mooring element:
This may be a synthetic fibre rope, a cable, a chain or a belt. It must always incorporate an absorber as a component of the fall-arrest system.

Energy absorber:
This impedes irreversible injury to the worker by arresting the fall under safety conditions.

Sliding fall-arrest devices:
These may be joined to:

  • A rigid anchor line.
  • A flexible anchor line.

Fall-arrest device with automatic or retractile retention:
This is composed of a container with a drum and a mooring element. It may optionally incorporate energy absorbers.

Connectors are used to join the devices and harness to one another and to the anchor points, which may be carabiners or a hook.
