A passive fall arrest system doesn’t require any action from the worker to provide protection—it's built into the environment. An active system, on the other hand, relies on the worker to properly wear and use personal fall protection gear.
Think of it like this: a guardrail is a passive system. It just exists—no buckles, no harnesses, no special training to use it. It’s always “on,” protecting anyone who’s working near it. It’s the kind of safety measure you can almost take for granted (though, of course, we never do!).
An active system includes gear like a full-body harness, a lanyard or SRL (self-retracting lifeline), and an anchor point. The worker has to put it on, hook in correctly, and make sure everything’s in good condition. It requires more responsibility and awareness, but it's essential in places where passive systems aren't feasible—like when you're working on a roof without a perimeter guardrail.
So why does this matter?
Because understanding the difference helps you choose the right solution for the job. Passive systems reduce the chance for human error, making them a great first line of defense. But sometimes, active systems are the only option, especially in more complex or mobile work environments.
At Colorado Safety Supply Company, we train crews on both—how to install, inspect, and use active systems, and how to integrate passive protections into your site plan. Whether you're setting up scaffolding or managing rooftop work, we’ve got the tools and knowledge to help you stay compliant and safe.
