I received an email from a Chief for whom Traditions Training had done some work with in the past. He was having problem and wondered if we could help. They, the “old school” firemen, and some of his “new school” firefighters, were having a disagreement as to the importance of and perhaps even the relevance of the SCBA waist strap. He asked me my opinion on the SCBA waist strap and its importance in relation to the safety of his members…..
We have all seen hundreds of photos of the unbuckled waist strap, it is found nearly monthly in each trade magazine. Whether they are photo’s of the FDNY, DCFD, PFD, NO-NAME-FD…it really doesn’t matter; the pictures don’t lie… it happens. Excuses can always be made they are easy….we aren’t focusing on those here. There are many advantages to having that strap fastened, some of which may just save your life.
The waist strap/belt on SCBA’s are just like the waist strap/belt on any “backpack” type framed device. The frame of a conventional hiking backpack carries the load “clothes, hiking gear…etc” to the shoulders and hips. The SCBA frame, carries the load “cylinder” to the same parts, your shoulders and hips.
The shoulders can carry the load alone when you have smaller weights (if you look at most smaller sized utility type day backbacks there is no waist strap/belt). However, when you get into the larger size backpacks (such as those for real hiking) you will usually find the waistband. The weight of our SCBA cylinders make the waistband a necessity when worn.
The SCBA waistband is designed to lessen the work load on our shoulders, as stated above sharing the load onto the hips (the muscles in our legs are stronger than our shoulder muscles). I find that I am able to do much more work with less exhaustion when I have the waistband on snug, and the shoulder straps left a bit looser. Shoulder movement (moving arms up and down like pulling ceilings) is often much harder when you have the shouder straps pulled tight.
While we all know that we can do the job either way (buckled or unbuckled) these SCBA frames are designed to be worn buckled. Crawling on our bellies and down low with the waist strap unbuckled can lead to things getting caught on the loose ends of the waist straps and may get us hung up.
Also, the waist strap provides some lateral stabillity when crawling especailly if we wind up awkwardly heading down a set of stairs or something….It will be better suited to stay on our backs when it is secure with the waistband.

To sum it up in a few short points:
WEAR YOUR BELT
1. Provides less chances of entanglement hazard when secured properly
2. Reduces fatigue on shoulders by transferring weight to hips
3. Provides stability from the mask moving laterally (left to right) especially when searching on hands and knees
4. Provides stability from the mask moving horizontally (up into back of helmet)
5. Provides stability when doing reduced profile and other tight quarter maneuvers
6. Members can quickly locate belt buckle to convert to harness if necessary
