Energy absorbent fall arrester.
Key Features
- Twin forked expandable lanyards.
- The energy absorber consists of a single component with a controlled-tear strap and one lanyard.
- In the event of a fall, the controlled-tear strap (energy dissipater) deploys from inside its plastic cover, breaking the fall. User safety depends on the continuous efficiency of the equipment and a clear understanding of the instruction in this users manual.
- Expandable energy absorbant fall arrester.
Design :
- 47/48 mm width and 2 m expandable length.
- 1 karabiners with 18 mm opening.
- 2 steel snap hooks with 58 mm opening.
Industry / Job : Construction & Civil, Rescue & Emergency, Travel & Tourism
Hazard / Risk : Fall
How To Use
Instructions for use & precautions:
- The fall arrester must be used with a fall arrester system as defined in the product data sheet (see standard EN355 and EN362).
- One of the energy absorber ends is linked to a harness (EN361) fastening point (dorsal or chest) and the order to the anchoring point using connectors EN362.
- Make sure that no obstacle can prevent the strap from unwinding normally.
- It is recommended that each user is allocated an energy absorber. The lanyard must only be used by one person at a time.
- Avoid use near sharp edges, thin structure or corrosion, for they may affect the strap performance.
- It is forbidden to add or replace any energy absorber component whatsoever.
- Temperature uses the equipment between -40°C and 50°C to avoid affecting its operation.
Limits to use:
- Check that the equipment anchorage point is located above the user (minimum resistance: 10kN) or that the general layout does not allow any free fall or any pendulum movements if a fall occurs.
- These fall arresters which are connected to the D ring dorsal attachment are only suitable if there is at least a 6-meter clearance from the anchorage point.
Instructions for storage:
- Store the lanyard system in a ventilated place away from humidity.
- Keep the device in its original packaging when not in use or when transporting.
- Check the condition of the strings and the stitching and rope protectors.
- At the time of Karabiner connection, check that the locking system is correctly in place.
- Transport the component or system in a package to protect it from any cuts, moisture or ultraviolet light. Avoid corrosive, overheated or refrigerated atmospheres (freezing temperatures).
Tests Conducted
- Dynamic performance: The harness is fitted to a 100kg solid torso dummy and connected via the harness attached to a 2-meter length of 11mm mountaineering rope (specifically chosen to generate a known force to the harness in the case of a fall). This rope is attached to a solid anchor point, and the dummy released over a distance of 4 meters. This test is carried out twice on each harness attachment, once from a head-up position, once from a head-down position (i.e. with the dummy upside down on release). In order to pass the test, the harness must hold the dummy following both drops, with the dummy held in a position not exceeding 50° from the upright position. These tests are repeated on every attachment point on a harness.
- Static strength: Whole products are subjected to tensile tests, based on a factor of safety on the 6kN expected in use. Harnesses are subject to a 15kN tensile force applied in the upward direction, followed by a 10kN force applied downward. Lanyards are subjected to either 22kN or 15kN applied between the attachment points, depending on the material used – an increased force as the lanyard is expected to be more exposed to aging factors such as abrasion in use. Tensile forces are usually applied and held for at least 3 minutes, to ensure the breaking strength of the product is in excess of the force specified by the standard.
- Corrosion resistance: Metallic components used in fall protection equipment are subjected to a neutral salt-spray test intended to prove a minimum resistance to environmental corrosion (specifically rust). Products are held within a sealed chamber, which is filled with a salt-water mist, which can induce rust in unprotected metals. Products are subjected to either 24 or 48 hours exposure and examined for rusting and function afterward.
Remarks
- The fall arrester must be used with a fall arrester system.
- It is forbidden to add or replace any energy absorber component whatsoever.
