2 Fall Protection Basics

3 Today We Will: Standards Hierarchy of Control Components –Connectors –Anchorages –Lanyards –Harnesses Special Systems –Rope Grabs –Lifelines –Ladder Systems Confined Space Rescue Systems Training

4 Regulations e c General statement Car droppers Bins & silos Drill masts

5 3 Blinks = 1 Second First blink18” from start Second blink6’ from start Third blink16’ from start

6 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

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

8 Phases of a Fall Onset Free fall Deceleration Rebound Suspension

9 The Fall... 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 On a 5 foot platform, you slip….

10 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

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

12 Fall Arrest Components Full body harness Connectors Lanyards Anchorages Mechanicals

13 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

14 Connectors D-rings Carabineers Locking snap-hooks Oval rings

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

16 Snaphooks

17 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

18 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

19 Anchorage Connectors Permanent –Remains in place for long time Temporary –Removed once use is completed

20 Lanyards Wire rope Web Synthetic rope

21 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

22 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

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

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

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

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

27 Mechanicals Self-retracting Lanyards Hoists Rope grabs Ladder grabs

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

29 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

30 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

31 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

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

33 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

34 Straps Thigh straps Sub pelvic straps –Under the buttocks –Strongest part of body –Natural seated position during suspension Shoulder straps

35 Fall Arrest Attachment Usually a d-ring Dorsal (back) d-ring –Between shoulder blades –Adjustable

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

37 Materials Nylon Polyester Back pads Comfort pads

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

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

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

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

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

43 Horizontal Lifeline Below beam system Stanchion system Continuous connection Shock absorber reduces fall arrest forces Versatile

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

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

46 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

47 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
