A fall arrest system protects workers from a fall when working at-height on a platform, climbing a ladder, or any other structure. The system is only used when a tech is working close to an edge, or exposed to a fall, but not actually in suspension. A Vertical Fall Arrest System is one version of this system. It usually takes the form of a single anchored line, or steel cable, and is used when ascending or descending a structure where the risk of an at-height fall exists. For example, when using a ladder.

During your IRATA Assessment, L2 and L3 certifying techs could be asked to demonstrate competence rigging a temporary fall arrest system to protect a vertical climb.

Your assessor will specifically be watching to make sure that you…

• Understand when it is appropriate to use this system, and when it is not.
• Take into account the clearance distance provided by the rope system (allowing for the possibility of rope stretch).
• Know and abide by any anchor strength requirements (including, how many users are permitted by the manufacturer on the system at one time). You should also know which standards an anchor should hold, according to WorkSafe BC, or your relevant local legislation.
• Have considered how a rescue could be performed.

We’ll discuss all of the above, as well as how this system could contribute to ease of access, during your training week.

This is part of an ongoing series, where we’re breaking down IRATA’s syllabus and clarifying exactly what ‘demonstrating competence’ and ‘demonstrating awareness’ means, and what will be expected of you on assessment day. As an IRATA L2 certifying tech, you’re expected to be fully competent with the L1 Syllabus. To return back to the IRATA L2 Study Guide or IRATA L3 Study Guide, click below:
