  6. 2.Safety solutions Safety solutions’ comparative table

  7. 3.Fall arrest system • Summary • Definitions • The body support • The fall arrester • The connection • The anchor

  8. Definition Equipment that secures one user at an anchor point in order to avoid any fall from height or to keep him in safety conditions. 3.Fall arrest system • Components associations Anchor point Fall arrester Body support system The anchor has to be positioned above the user

  9. 3.Fall arrest system • Shock impact Shock impact When a fall occurs, the user supports a shock impact with possible injuries. 400 kNthreshold value for cervic bruising 600 kN threshold value acceptable for the human body 1000 kN maximum limit : severe bruising – lethal risk-

  10. Clearance (T) Distance between the anchor point and the nearest obstacle. T T 3.Fall arrest system • Definitions
