System Selection Guide: How to Choose the Right Fall Protection System
If you’re looking to install a comprehensive fall protection system for workers, follow this simple system selection guide to help identify the best system for your application. After you have supplied a brief answer to the questions listed below, you can move through the rest of the selection guide to provide exact specifications for your fall protection needs.
Things to Consider Before Moving Through the Steps Below:
- Which area of the facility requires fall protection?
- How many workers will be using the system at one time?
- Does your application require workers to be able to pass one another while attached to the system at the same time?
- How will the system be supported?
- What type of lanyards and harnesses will you need to supply?
- Where will workers initially connect to the fall protection system? Is there a location for a tagline to hang down without interfering with an overhead crane or other equipment? Can a tagline be stored out of the way or in a location that is easily accessible for workers?
- If a worker falls off the edge of a work area, how many degrees off-center will the lanyard line be?
- How will you rescue a fallen worker?
Step 1: Coverage Area and Hook Distance
To identify the best system for your particular needs, start by specifying your required coverage area and hook distance. In other words, consider the following questions:
1. Where in your facility do your workers need fall protection?
2. Calculate the length, width, and height of that specific area.
- You can reference our height to coverage width calculator below to determine height requirements for your facility. It’s important to note, however, that most Rigid Lifelines’ Anchor Track systems allow workers to be 30 degrees off plumb (also known as off center).
The height to coverage width calculator helps you to determine your coverage area and hook-to-surface distance. Use the chart below—along with the coverage drawing (Figure 1)—to determine your coverage area and hook distance:
Step 2: Worker Capacity:
After you’ve determined your coverage area and hook distance, you will need to determine your worker rating for the system. Your worker rating will depend on how many workers you will need to attach to the system at one time. At this point, you will also want to consider whether or not your workers will need to pass one another while attached to the system.
- To calculate your worker rating for the system, first decide how many workers will need to attach to the system at the same time.
- Keep in mind that 900 pounds of maximum arresting force (MAF) is considered the threshold for injury. In other words, if your maximum arresting force on each worker is 900 pounds or less, the potential for injury in the event of a fall is far less.
- Keep in mind that 310 pounds is the standard maximum working load capacity allowed per user by OSHA and ANSI standards, meaning system tests are conducted to simulate arresting the fall of up to a 310-pound worker. 310 pounds includes the person and any tools. If the working load including tools exceeds 310 pounds, then special equipment and/or a higher system rating must be used. Special equipment would be full-body harnesses and self-retracting lanyards rated for more than 310 pounds.
Step 3: Permanent or Mobile Fall Protection:
The next step in selecting the right fall protection solution is to decide which type of system your application requires. This process includes deciding whether your operation needs a permanent or mobile system. In addition, it’s important to take the following information into consideration before moving to the next step.
1. Permanent fall protection systems can be mounted to ceilings, walls, or the ground to provide a constant fall arrest solution. Permanent systems are critical for workers who are exposed to or working at heights in the same location. Ask yourself, are there any obstructions that would prevent mounting a continuous system? Are there obstructions that would prevent the travel and operation of a self-retracting lanyard (SRL)?
- If you have decided that your application requires a permanent fall protection system, you will need to consider the best way to mount your system according to your facility and operation. In other words, does the track need to be mounted overhead to an existing ceiling structure? Or, is there a column near the specified coverage area that can support the weight of a column-mounted system? Or, is there floor space next to the specified coverage area to place a freestanding column or multiple columns?
2. Mobile (or portable) fall protection systems are ideal for temporary work stations. By using forklifts, heavy-duty pickup trucks, or workers, you can move our mobile systems to any location that needs fall protection. Mobile systems do not require any type of foundation or mounting, and they provide the convenience of mobility without sacrificing the reliability of rigid track. Ask yourself, is there enough space on the ground near the specified coverage area to place a portable base? Do you have a forklift with the capacity to move the counterweighted system? If there isn’t enough space for a portable base or a forklift with the required capacity, is there enough space on either side of the coverage area to place wheeled uprights?
- If you have decided that your application requires a mobile fall protection system, you will need to consider the best way to move the system from one location to another—depending on your individual needs. In other words, will you need to move the system with a forklift or by hand? If you prefer to move the system using a forklift, a skidded system is a great solution. If you prefer to move the system by hand, a Rolling A-Frame is a great solution. If you are planning on moving the system by hand, be sure you have at least two workers available to push the system by hand from one point to another.
Step 4: Fall Protection Models:
After you have decided whether your application requires a mobile or permanent solution, and you have taken system specifications into consideration, you can begin exploring the different fall protection systems that meet your specific application. If you still feel like you could use some help selecting the right fall protection system, contact a local Rigid Lifelines’ representative today to schedule an onsite assessment.
