BS EN 358:2000

When work undertaken at a height is of short duration, or for technical reasons the provision of a working platform, suitable barriers and other similar safeguards is impractical, then safe working at height can be carried out by using personal protective equipment.

Equipment written to BS EN 358's specifications is designed either to secure the user safely in position or restrain them to prevent them from falling.

The standard applies to belts and lanyards meant for positioning or restraint. It sets out the requirements for testing, marking and the information supplied by the manufacturer.
