4 components of a personal fall arrest system
4 Components of a Personal Fall Arrest System
  • Body Support
    • Body Belts
    • Full Body Harness
  • Connectors
    • Lanyards
    • Self Retracting Lifelines
    • Vertical and Horizontal Systems
  • Anchorage
    • Engineered
    • Non Engineered
  • Rescue
full body harness
OSHA 1926.502 (d) (16) (ii):

Personal fall arrest systems shall limit the maximum arresting force on an employee to 1,800 pounds (8 kN) when used with a body harness.

ANSI

Fall Arrest

(always must have)

Dorsal D-Ring

Full Body Harness
connectors
Connectors
  • Snap hooks and carabiners must be self-locking and self-closing.
  • All connectors must meet 5000lbs.
  • All connectors must be connected to a compatible connection.
  • NEW ANSI Standard (11/2007)
    • Connectors shall meet 5000 lbs. and the gate shall meet 3600 lbs.
lanyards
Lanyards

Many different types of lanyards

Needs to be able to reduce energy from 5000 lbs force to…

1800 lbs for OSHA

ANSI 900 lbs or less……

shock absorbing lanyards
Shock Absorbing Lanyards

Always connect the shock pack to the Dorsal D-ring

Make sure you are not exceeding the weight limit of the lanyard

Never connect two lanyards together

100% Tie-Off

clearance calculations
General Rule:

“You need 12.5 ft of clearance with a 6 ft lanyard”

6.0 ft for Free Fall

3.5 ft for Deceleration

1.0 ft for D-ring slide

2.0 ft for Safety Factor

12.5 ft clearance required

Freefall

+

Deceleration

+

Safety Factor

Clearance Calculations
clearance calculation
What if I don’t have 12.5 ft of clearance?

Raise the anchor point

Use a shorter lanyard

Use a SRL

SRL Example

3.5 ft for Deceleration

1.0 ft for D-ring slide

2.0 ft for Safety Factor

6.5 ft clearance required

Clearance Calculation
anchorage and anchorage connectors
Anchorage and Anchorage Connectors
  • Anchorages are defined as secure points to attach an anchorage connector to be used in conjunction with a fall protection or rescue system.
  • Anchorages used for fall protection shall be capable of supporting a load of 5,000 lbs. per worker, unless certified by a qualified person who maintains a 2:1 safety factor.
  • The maximum arresting force (MAF) on the anchor shall be no more than 1,800 lbs.
rescue escape
OSHA 1926.502 (d) (20):The employer shall provide for prompt rescue of employees in the event of a fall or shall assure that employees are able to rescue themselves.

ANSI Z359.2 Rev. If emergency services are not able to answer a request for assistance in a timely manner or if they do not have adequate equipment, then companies should have in-house rescue procedures and trained personnel in place

Program effectiveness should be evaluated at regular intervals of no more than two years
