One of the key factors in the selection of a fall protection is its weight. Why? Well, because this thing is going to be hanging off of your back. Add a full 8 hour work day to the equation and you're going to be in a world of hurt when it's time to clock out. How can you fix this? It's very simple.
If you spend an unnatural amount of time with your lanyards, you'll want to consider an internal shock lanyard. These lanyards don't utilize a shock pack like most lanyards. Instead, with an internal shock lanyard, the webbing is sewn together so that when a fall occurs the webbing peels apart giving you a nice cushy landing. Shock packs add weight. The internal shock lanyards are the lightest on the market, and I would highly recommend it.
If you want to go a step further, consider getting yourself an internal shock stretch lanyard. The stretch lanyard will expand as you use it and keep your lanyard from dragging across the ground. It might add a little weight, but you won't be dragging your lanyard behind you. It should add to the life of your lanyard!
Hopefully, this little tip will help you find a lanyard that cuts down on fatigue.
