Sala Advanced Portable Fall Arrest Post System with a Wide Choice of Fall Arrest Inertia Reels
Model: APFS-3527
Compact, lightweight design ideal for use on top of transformers or other types of vertical platforms with potential fall hazards.
The Advanced Portable Fall Arrest Post is specifically designed for use on top of transformers or other types of vertical platforms with potential fall hazards. It’s compact and lightweight design of only 38 lbs makes the post very easy to transport and put in place.
The system features 3 independent swivel anchor points. They can rotate 360 degrees, offering freedom of mobility for up to 3 workers with self-retracting lifelines or fixed length lanyards.
Features
- Provides three independent swivel tie-off points for fall arrest anchorage (Three worker maximum in any configuration).
- Three-stage/four-position telescoping design and aluminum construction for easy transportation and set-up.
- Leveling screws allow the system to be plumbed to vertical on inclines up to 15 degrees.
- Portable and fixed bases allow for versatile usage.
- Suggested Applications: Electrical transformers, leading edge deck work, confined space and rescue, industrial presses, bridge cranes, large cranes, limited horizontal lifeline applications.
The Working Radius of Portable Fall-Arrest System (PFAS)
The Portable Fall-Arrest System has 3 telescopic working heights ranging from 30.5” (774 mm) 43” (1092 mm), all the way up to 54.5” (1384 mm). This decreases a worker’s fall distance and increase the overall work area. *NOTE: The Rescue Davit Arm works in the 2nd and 4th positions only.

Safe Working Area
The DBI-Sala (UCL) Advanced Portable Fall Arrest System offers a six foot (1829 mm) radius or twelve foot diameter (3658 mm) Safe Working Area. This means that a maximum of three persons can work within six feet of the post within the design parameters set forth by UCL.
Design Criteria
UCL engineers have derived a worst case scenario of two people falling simultaneously when the structure is already supporting a previously fallen third person (who may weigh up to 300 lbs). All people are equipped with a shock absorber of 900 lbs Maximum Arresting Force (M.A.F.).
Applying an industry accepted 2:1 design factor to this worst case loading of 2100 lbs (9.34 kN) or broken down {(900 lbs + 900 lbs + 300 lbs) x 2}, we arrive at 4200 lbs (18.7 kN) as a proof load for the structure. This design factor is laid out in the OSHA regulations for engineered systems.
Compare Design Criteria
THIS IS IMPORTANT! The angle at which a load is applied greatly affects the load the structure can support. The further away from the post that you apply the force, the stronger the post has to be to provide the stated proof load. An anchor post with a 4200 lbs proof load that is tested from six feet away is much STRONGER and SAFER than one tested from, for example, two feet away. In fact, the maximum safe working area of a fall protection anchor post is normally defined by the distance from the post (or angle) that the proof load test is done at. Since the UCL Portable Fall Arrest System Post is designed to protect 3 workers working within a six foot radius of the post, the worst case proof load test was applied six feet
away from the centerline of the post.
Cost Benefit
The larger the safe working area of an anchor post is the fewer anchor posts are needed to protect the working area. You need fewer posts and fewer uni-anchor base locations to cover a given area effectively. This translates into less cost to cover a given area and fewer potential obstructions for workers.
