Personal fall arresting system<\/strong> is formed when a safety belt<\/strong> works with an appropriate anchorage system.<\/strong><\/p>\n

Personal fall arresting system<\/strong> = safety belt<\/strong> (i.e Safety harnesses) + anchorage system<\/strong><\/p><\/blockquote>\n

Classification of Safety Belts\u00a0 \u00a0x5<\/h5>\n

Safety belts can be classified under various national standards as :-<\/p>\n

    \n
  1. Safety-harness or full body harness<\/li>\n
  2. Semi-harness or chest harness<\/li>\n
  3. General purpose safety belt<\/li>\n
  4. Work positioning belt, pole safety belt, or linesman safety belt<\/li>\n
  5. Rescue harness<\/li>\n<\/ol>\n

    These safety belt work with lanyards, fixed anchorages, indepedent lifeines, or fall arresters. It is important that full investigations be conducted before purchase of safety belts and selection of anchorage system to determine the correct type of appliances that most suit the clss of work and the environmental conditions.<\/p>\n

     <\/p>\n

    Safety Harness or Full Body Harness<\/h5>\n

    Safety harnesses<\/strong> = Thigh straps (\u80a1\u5e36) + Shoulder straps (\u80a9\u5e36) + Safety lanyards (\u5b89\u5168\u61f8\u639b\u7e69)<\/p><\/blockquote>\n

     <\/p>\n

    Two common types of anchorage system<\/strong> :<\/p>\n

      \n
    1. Safety harnesses \u2192\u00a0 anchorage points<\/strong> (\u7e6b\u7a69\u9ede) via : D-ring<\/strong>
      \nOR<\/li>\n
    2. Safety harnesses \u2192 Indepedent safety line<\/strong> (\u7368\u7acb\u5b89\u5168\u7e69) via positioning devices<\/strong><\/li>\n<\/ol>\n

       <\/p><\/blockquote>\n

      In general, “safety harnesses (\u5b89\u5168\u540a\u5e36)” are harnesses incorportating “thigh straps (\u80a1\u5e36)” and “shoulder straps (\u80a9\u5e36)” used in conjunction with “safety lanyards (\u5b89\u5168\u61f8\u639b\u7e69)”, for attachment to “anchorage points (\u7e6b\u7a69\u9ede)”or”safety line (\u5b89\u5168\u7e69)”.<\/p>\n

      The D-ring or other equivalent facility provided for the attachment of the “lanyard (\u61f8\u639b\u7e69)” is located in the upper part of the harness so that angle formed between the spine of a suspended user and the safety lanyard does not exceed a certain angle specified by the national standards.<\/p>\n

      All straps (\u6240\u6709\u5e36), including any waist belt (\u8170\u5e36), shall be capable of adjustment to fit the user and mean of adjustment shall be provided. The harness may be incorporated within a garment.<\/p>\n

      The harness should provide support for the body around the lower chest, over the shoulders and around the thighs.<\/p>\n

       <\/p>\n

      Selection of the type of anchorages<\/h5>\n

      The selection of the type of anchorages will depend on the nature and location of the task and the type of construction of the building or supporting structures. Prior to selecting an anchorage, an assessment of the workplace conditions should be made by a competent person. The equipment and anchorage point must match the work situation and workplace environmental factors.<\/p>\n

       <\/p>\n

      Vertical Indepedent Lifeline<\/h5>\n

      Indepedent lifeline = lanyard + positioning devices (e.g rope chuck, rope grab, rope adjuster)<\/p><\/blockquote>\n

      Indepedent lifeline<\/strong> works with a lanyard<\/strong> and a positioning devices<\/strong> such as a “rope chuck (\u7e69\u7d22\u593e\u982d)”,”rope grab (\u7e69\u7d22\u6293\u9264)” or “rope adjuster (\u7e69\u7d22\u8abf\u7bc0\u5668)”, the upper end of which is securely attached to a structural anchorage point.<\/p>\n

      The lifeline can be of fibre rope or metal cables. The minimum d<\/strong>iameter of a fibre<\/strong> rope life line is 15.9 mm<\/strong> under ANSI;<\/strong><\/p>\n

      Metal<\/strong> cables used for lifeline shall have a minimum d<\/strong>iameter of 8 mm<\/strong> and a minimum static breaking strength<\/strong> of 25 kN<\/strong> when tested in accordance with EN<\/strong> 12385-1:2002.<\/p>\n
