Miller Fall Protection Fall Clearance Calculator

We’ve talked before on this blog about the “fall clearance” issue. Essentially fall clearance has to do with the distance you need to account for when taking a fall in order not to hit the ground. What this means is that if you are 6 foot tall, wearing a 6 foot lanyard, accounting for stretch and other factors, you will need to have 18 feet off fall clearance as illustrated below.


Because factors vary (You might be using a self-retracting lifeline or an 8 foot lanyard, for example) each application should be looked at separately and the fall clearance calculated for each instance. Fortunately, Miller Fall Protection has a fall clearance calculator that you can use to determine your fall clearance. Just type in your variables and it’ll give you your fall clearance, illustrated as in the above image.

Great little tool to keep everyone safe!


Understanding the Fall Distance Calculation

You’ve heard it over and over again… ” If you are more than six feet off the ground you need to be tied off”.

Understanding the fall distance calculation, however, is important to the “how” of being tied off.

It’s simply an issue of addition. Let’s look at the different part that we need to add up:

  • Lanyard Length: six (6) feet total
  • Deceleration Distance: Three and a half (3.5) feet
  • Distance from the sole of the feet to the top of the back D-ring once the fall has occurred: Six (6) feet
  • Safety Factor: three (3) feet

Now, let’s add these up: 6 + 3.5 + 6 + 3 = 18.5 feet

What this means is that if you take a fall when you anchor point is lower than 18 ½ feet above the ground (or the floor, at whatever level you are at) then you stand a very good chance of getting seriously injured or even killed.

Guardian Fall Protection provides us with this illustration:

So next time you’re looking for an anchor point, just remember that it needs to be at least 18.5 feet above the surface you are trying to keep from impacting.
