  4. 3 Blinks = 1 Second • First blink 18” from start • Second blink 6’ from start • Third blink 16’ from start

  5. Types Of Falls • Same surface falls • Slips • Trips (very common, not very severe) • Falls on stairs • More severe than same surface falls • Falls from heights • Lower frequency, but most severe

  6. Falls From Heights • A Few Examples: • From machinery • From overhead cranes • Working on conveyors • From silos • Working at roof edges and openings • From scaffolding

  7. Phases of a Fall • Onset • Free fall • Deceleration • Rebound • Suspension

  8. The Fall... On a 5 foot platform, you slip…. • Fall 2 feet, arrester locks & applies stopping force to your body • Time of fall is 1/3 of a second • Stopping force is applied to strong bones & muscles under buttocks • You decelerate to complete stop • You hang until rescued

  9. 3-2-1 STOP!! • In a 3’ fall a 200 pound person will generate enough speed & inertia that it will take almost 1 ton of energy (2000 foot pounds) to stop

  10. Hierarchy of Controls • Remove fall hazard through engineering redesign • Implement collective fall protection measure • Implement personal fall protection & arrest system

  11. Fall Arrest Components • Full body harness • Connectors • Lanyards • Anchorages • Mechanicals

  12. Preventing Injury • Use full body harness with fall arrester prior to climbing (with built-in shock absorber) • Connect arrester to harness d-ring on back between shoulder blades • Fall arrester connected to anchor

  13. Connectors • D-rings • Carabineers • Locking snap-hooks • Oval rings

  14. Connectors • Most frequently used part of system because of worker movement • Used to connect different parts of system • Also called “hardware”

  15. Snaphooks

  16. Carabineers • Trapezoid or oval shaped • Gate opens to connect • Different sizes (width) • Aluminum or alloy steel • Pulling force of 5000 lbs • Normally independent component, but may be attached

  17. D-rings • Used on lanyards, lifelines, & anchorage points • Attachment element on harness • Made of steel • Minimum strength of 5000 lbs • Corrosion resistant • Max on harness is 6

  18. Anchorage Connectors • Permanent • Remains in place for long time • Temporary • Removed once use is completed

  19. Lanyards • Wire rope • Web • Synthetic rope

  20. Lanyards • Used for fall arrest and positioning and personal restraint • Incorporate an energy absorber when used for fall arrest • Most common connector is the snap-hook

  21. Lanyards • Wire rope lanyards • High heat applications • Only fixed lengths • Less “stretch” • Rebar lanyard • At least 9/32 inch diameter • Snaphooks at each end attached to hip d-rings

  22. Dyna-Brake® Lanyards • Fixed or adjustable lengths • Shock absorber limits fall arrest forces • Twin leg for continuous connection • Polyester or nylon material

  23. Rope & Wire Lanyards • Rope available in nylon • Fixed or adjustable lengths • Shock absorber limits fall arrest forces • Available in twin leg model

  24. Shock Absorbing • Elastic material reduces possibility of trips and snags • Available in twin leg model • Shock absorber limits fall arrest forces

  25. Tie-Back™ Lanyard • Nylon material • Shock Absorber • Twin leg style available • Integral D-ring • Meets ANSI regulations

  26. Mechanicals • Self-retracting • Lanyards • Hoists • Rope grabs • Ladder grabs

  27. Self-Retracting • Minimizes freefall distance & fall arrest forces • Arrests fall within inches • Meets ANSI A10.14 regulations

  28. Self-Retracting • Contains a drum- would line • Slowly extracted or retracted from housing • Connects to fall arrest attachment on harness • Device locks drum at onset of a fall

  29. Self-Retracting • SRL with emergency retrieval capability • Able to be reset from retrieval mode to fall arrest mode • Unique “key” feature, enables only authorized people to reset • Used with Lynx Tripod or Ropod • Does not replace Dynevac II

  30. Remote System • Telescoping pole allows for connections up 20’ overhead • Connect before leaving ground • System includes pole, AC strap, strap tool, connect/disconnect tool, and carrying bag

  31. Full Body Harness • Nylon or polyester • Webbing • Metal d-rings • Highest level of protection and force distribution

  32. Full Body Harnesses • Preferred for most applications • Highest degree of protection • Distribute forces to strongest part of human body • Better for suspension • Straps color coded for easy identification

  33. Straps • Thigh straps • Sub pelvic straps • Under the buttocks • Strongest part of body • Natural seated position during suspension • Shoulder straps

  34. Fall Arrest Attachment • Usually a d-ring • Dorsal (back) d-ring • Between shoulder blades • Adjustable

  35. D-Rings • Shoulder • Retrieval from confined spaces • Chest • Personnel riding, climbing • Not for positioning • Not used in fall arrest • Hip • Positioning • Personal restraint

  36. Materials • Nylon • Polyester • Back pads • Comfort pads

  37. Pullover Harness • Single point of adjustment • Easy donning and doffing • Nylon or polyester • Sub-pelvic support strap • Color coded straps

  38. Vestype™Harness • Three shoulder strap adjustment points • Nylon or polyester • Sub pelvic support strap • Color coded straps

  39. Tradesman™ Harness • 6” wide back pad with hip d-rings • Tool belt support straps • Permits hands-free climbing

  40. Rope Grab • Device which travels on a lifeline & will automatically engage lifeline to arrest a fall • Classified by horizontal or vertical lifeline style

  41. Rope Grab • Hands free operation while ascending or descending • Versatile, lightweight, and economical • Easy to install • Limits free fall distance to 6’ or less

  42. Horizontal Lifeline • Below beam system • Stanchion system • Continuous connection • Shock absorber reduces fall arrest forces • Versatile

  43. Descender • Rescue & evacuation device • Automatically controls rate of descent to ground • 50’ or 105’ wire rope • Descent rate of 6.5’ per second

  44. Descender • Rescue & Evacuation Device • User controls rate of descent • Versatile • 50’, 100’ or 150’ rope

  45. Dyna-Glide™ System • Permanent system • Vertical or horizontal • Hands-free climbing, work positioning, travel restriction, and fall arrest • Mounted to existing ladders or structures • Used by more than one person at a time

  46. MSA President’s Promise • A fall is experienced • Harness & lanyard • One time use • Contact MSA/distributor • Complete incident report • MSA will replace at no charge
