  3. 3. What is “Work at Height” ? <ul><ul><li>Working close to excavations or opening where someone could fall in </li></ul></ul><ul><ul><li>Work on staging or trestles (e.g. concerts or filming) </li></ul></ul><ul><ul><li>Using Ladders, steps, or kick stool </li></ul></ul><ul><ul><li>Working in a mine shaft </li></ul></ul>
  4. 4. Fall arrest system
  5. 5. Full-body harnesses and belts <ul><li>Full- body harnesses wrap around the waist, shoulders and legs. A D-ring located in the center of the back provides a connecting point for lanyards or other fall arrest connections devices </li></ul><ul><li>Belts are udes in positioning system aplications. These belts have two side D-rings, and are used only for restraining a worker in position. This type of belt is not used for any vertical free fall protection </li></ul>
  6. 6. Attachment Location <ul><li>The attachment of the body harness must be located in the center of the wearer´s back, near the shoulder leve, or above the head. </li></ul><ul><li>OSHA Standard: 1926.502 (d) (17) </li></ul>
  7. 7. Body harness <ul><li>Body harnesses are designed to minimize stress forces on an employee´s body in the event of a fall, while providing sufficient freedom of movement to allow work to be performed </li></ul><ul><li>Do not use body harnesses to hoist materials </li></ul>
  8. 8. <ul><li>Vertical lifelines or lanyards must have a minimum breaking strength of 5000 pounds, and be protected against being cut or abraded </li></ul>Vertical lifelines/ lanyards
  9. 9. Self-retracting lifelines/ lanyards <ul><li>Self-retracting verticak lifelines and lanyards that automatically limit free fall distance to 2 feet or less must be capable of sustaining a minimum tensible load of 3000 pounds when in the fully extended position </li></ul>
  10. 10. Horizontal lifelines <ul><li>Horizontal lifelines are to be designed, installed and used under the supervision of a qualified person, and as part of a complete personal fall arrest system which maintains a safety factor of at least two. </li></ul>
  11. 11. Webbing <ul><li>Webbing are the ropes and straps used in lifelines, lanyards, and strength components of body harnesses. The webbing must be made from synthetic fibers. </li></ul>
  12. 12. Connectors <ul><li>Connectors, including D-rings and snaphooks, must be made from drop-forged, pressed or formed stell, or equivalent materials. They must have a corrosion-resistant finish, with smooth surfaces and edges to prevent damage to connecting parts of the system </li></ul>
  13. 13. D-rings <ul><li>D-rings must have a minimum tensile strength of 5000 pounds and be proof-tested to a minimum tensile loead of 3600 pounds without cracking, breaking, or becoming permanently deformed. </li></ul>
  14. 14. Snaphooks <ul><li>Snaphooks must have a minimum strenght of 5000 pounds, and be proof tested to a minimum tensile load of 3600 pounds without cracking, breaking or becoming permanently deformed. </li></ul>
  15. 15. Anchorages <ul><li>Anchorages used for attachment of personal fall arrest equipment must be independent of any anchorage being used to support or suspend platforms, and capable of supporting al least 5000 pounds per employee attached, or must be designed and used as follows: </li></ul><ul><li>Under supervision of a qualified person </li></ul>
  16. 16. <ul><li>As part of a complete personal fall arrest system which maintains a safety factor of al least two </li></ul>
  17. 18. Guardrails <ul><li>Guardrails are the primary means of fall protection in industry and construction </li></ul>
