Fall Arrest Blocks
Fall arrest blocks must conform to EN360, they are retractable inertia reel devices designed for use overhead. The block is fitted with either a galvanised or stainless steel cable some blocks even webbing for the retractable section.
Some of our blocks that feature a retrieval/winch handle to recover a fallen casualty, these are particularly useful when working in confined spaces. Users should be aware that a fall over an edge or a pendulum could damage the webbing or the wire if in doubt ALWAYS seek more information from ourselves or the manufacturer.
Fall indicators are now available on most types of fall arrest block, either fitted within the device itself or at the connecting swivel. Should these indicators show that the device has arrested a fall then it must be returned to ourselves or the manufacturer for servicing or repair as appropriate.
Fall distances are very short when using fall arrest blocks, thus an energy absorber is usually not required. Fall arrest blocks must not be used where a fall into a free flowing material, for example grain or sand, could be encountered or on a sloping roof as the devices need a sudden jerk to activate the locking mechanism. A falling into a free flowing solid will not allow the device to lock up, likewise sliding down a roof may not create enough impact for the device to initiate. Manufacturer's instructions provide advice on the angles at which these devices may be used, they must be followed.
Tip:If a block is permanently fixed overhead a removable cord can be used to retrieve the connector. Never let the device retract quickly as this may cause internal problems to the device, with a retrieval cord fitted the rate of retraction can be manually slowed.
