Study Notes
Personal Fall Arrest System (PFAS) Components
- Full-body harness: Essential protective body wear with straps positioned around shoulders, thighs, buttocks, and hips.
- Body belt: Used solely as a positioning device, wrapped around the waist.
- Lanyard: Connects harness to a secure anchorage point; made of rope, webbing, or steel cables.
- Anchorage point: Must be a secure attachment point for the entire system.
- Self-retracting lifeline: Automatic brake system that allows mobility while limiting free fall.
Basic Components of PFAS
- Approved anchorage point: Must support the system.
- Full body harness: Primary protective garment.
- Connecting device: Joins components of the PFAS.
Weight Requirements
- Anchorage point capacity: Must support at least 5,000 pounds for each attached worker.
Purpose of PFAS
- Fall arrest function: Designed specifically to stop a person from falling from a height.
Full-body Harness Specifications
- Designation: The only permissible body-holding device within PFAS.
- Construction: Comprises straps that secure the worker.
Acceptable Anchorage Points
- Independence: Should not rely on any means that supports or suspends the worker.
- Accessibility: Must be reachable without exposing the worker to hazards.
- Protection: Location must prevent contact with any lower-level hazards during a fall.
Fall Distance Limits
- Free fall restriction: The anchorage height must ensure a maximum free fall distance of 6 feet.
Connecting Device Selection
- Factors to consider: Choice of device depends on potential fall distance, total weight carried, and specific work conditions.
Shock-absorbing Lanyards
- Absorption capability: Designed to reduce stopping force by up to 80% compared to standard lanyards.
Rope Grab Functionality
- Mechanism: A friction-based device that serves to arrest a fall.
