Regulations


3 blinks 1 second
3 Blinks = 1 Second

  • First blink 18” from start

  • Second blink 6’ from start

  • Third blink 16’ from start


Types of falls
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


Falls from heights
Falls From Heights

  • A Few Examples:

    • From machinery

    • From overhead cranes

    • Working on conveyors

    • From silos

    • Working at roof edges and openings

    • From scaffolding


Phases of a fall
Phases of a Fall

  • Onset

  • Free fall

  • Deceleration

  • Rebound

  • Suspension


The fall
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


3 2 1 stop
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


Hierarchy of controls
Hierarchy of Controls

  • Remove fall hazard through engineering redesign

  • Implement collective fall protection measure

  • Implement personal fall protection & arrest system


Fall arrest components
Fall Arrest Components

  • Full body harness

  • Connectors

  • Lanyards

  • Anchorages

  • Mechanicals


Preventing injury
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


Connectors
Connectors

  • D-rings

  • Carabineers

  • Locking snap-hooks

  • Oval rings


Connectors1
Connectors

  • Most frequently used part of system because of worker movement

  • Used to connect different parts of system

  • Also called “hardware”



Carabineers
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


D rings
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


Anchorage connectors
Anchorage Connectors

  • Permanent

    • Remains in place for long time

  • Temporary

    • Removed once use is completed


Lanyards
Lanyards

  • Wire rope

  • Web

  • Synthetic rope


Lanyards1
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


Lanyards2
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


Dyna brake lanyards
Dyna-Brake® Lanyards

  • Fixed or adjustable lengths

  • Shock absorber limits fall arrest forces

  • Twin leg for continuous connection

  • Polyester or nylon material


Rope wire lanyards
Rope & Wire Lanyards

  • Rope available in nylon

  • Fixed or adjustable lengths

  • Shock absorber limits fall arrest forces

  • Available in twin leg model


Shock absorbing
Shock Absorbing

  • Elastic material reduces possibility of trips and snags

  • Available in twin leg model

  • Shock absorber limits fall arrest forces


Tie back lanyard
Tie-Back™ Lanyard

Mechanicals
Mechanicals

  • Self-retracting

  • Lanyards

  • Hoists

  • Rope grabs

  • Ladder grabs


Self retracting
Self-Retracting

  • Minimizes freefall distance & fall arrest forces

  • Arrests fall within inches

  • Meets ANSI A10.14 regulations


Self retracting1
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


Self retracting2
Self-Retracting
