Fall Arrest Systems
Alpine Fire and Safety Systems is committed to finding solutions in fall prevention -- with products, service and support information.
The ABC’s of Personal Fall Arrest Systems or PFAS should always be in place to provide ultimate worker protection.
Anchorage/Anchorage Connectors:
Anchorage, commonly referred to as a tie-off point, example, rebar, scaffolding, etc must be capable of supporting 5000lbs of force per worker.
An anchorage connector is used to join the connecting device to the anchorage, some examples are cross-arm strap or D-bolt.
Body Wear:
The only form of body wear acceptable for fall arrest is the full-body harness and it should be selected based on the job at hand and environment, there are many styles from which to choose.
Connecting Device:
This is the critical link which joins the body wear to the anchorage/anchorage connector, some examples are a shock-absorbing lanyard or self-retracting lifeline. Potential fall distance must be calculated to determine type of connecting device to use.

It’s important to remember that these items, individually, do not provide protection from a fall. However used in conjunction with each other they form a PFAS that is vitally important to safety on the jobsite!

Calculating Total Fall Clearance Distance
Shock-absorbing lanyards extend deceleration distance
during a fall, significantly reducing fall arrest forces by
65 to 80 percent below the threshold of injury. This
ensures greater safety on the jobsite. However, when using
a shock-absorbing lanyard, it is important to understand
how to calculate potential fall distance to avoid contact
with a lower level.

Calculating Your Potential Fall Distance
1. When using a 6 ft. (1.8m) shock-absorbing lanyard and
a full-body harness, first add the length of the shock-
absorbing lanyard [6 ft. (1.8m)] to the maximum elongation
of the shock absorber during deceleration [3-1/2 ft. (1.1m)]
to the height of a worker [6 ft. (1.8m) average].
2. Then, add 3 ft. (1m) as a safety factor.
3. The total, 18-1/2 ft. (5.6m) is the estimated safe fall
clearance distance, the height at which you must attach
to an anchorage to minimize the risk of contact with a
lower level.
WARNING: Before using a shock-absorbing lanyard or self-retracting lifeline, calculate your fall distance and select the proper equipment to meet estimated fall clearance. Failure to select proper equipment and calculate fall distances may result in serious personal injury, illness or death.
