FALL ARREST Your very personal safety Some key aspects

The Red Line Through Fall Arresting All the fall arrest equipment shown here has an upper load capacity far in excess of what a Person could stand. It is Safe only when correctly used. Always Read the User Instructions Carefully before use. 1. The Anchor Point No fall arrest system is stronger than its weakest link. Make sure that the anchor point can withstand the impact caused by a fall. 2. The Lanyard A choice for every situation: When used for support a rope/strap/webbing is chosen, secured to the belt and to the anchor point. Maybe round the anchor point and back to the belt. Easy length adjustment gives optimum support. As fall arrester the line shall stretch from the anchor point to the harness. The maximum force at the end of a fall must not exceed 6 k. N. Use only one shock absorber per unit

The Red Line Through Fall Arresting 3. Harness or Belt According to the task at hand. Harness shall be used wherever there is the risk of a fall. Also when working in tanks, wells, silos, and other enclosed areas, irrespective of whether they are above or under ground level Waist Belt may be used for support only, to let the user have both hands free to work. A harness can also be used for support and may indeed be shaped as a waistcoat. 4. Maintenance Equipment that has been subjected to shock or excessive load shall be sent for inspection or be replaced. All fall arrest equipment should be inspected at least once a year. Fall arrest equipment is in general colored as a reminder that it must be used only for securing a person.
