I have a 'continuing' discussion with a few people (all of whom have only ever worked with/on ladders since joining the department) about the right way to foot (or heel) a ladder. Granted I was "taught" the fire service way -to stand beneath the ladder holding the rails- but when I'm footing the ladder I stand facingit (and when climbing I'd prefer the footer do the same).
I've done carpentry/construction for years and have never seen anyone stand beneath a ladder. The risk of being hit by dropped tools/materials is too great. Yet the fire service still teaches this method.
In my opinion, footing the ladder while facing it allows the footer to watch the FF climbing, be aware of any hazards (including dropped tools) and, under conditions or situations where the ladder might slip, allow the footer to actually stand on the bottom rung for additional ballast.
I'm not looking for a poll as to which way you do it but rather, sound arguments for one way or the other.
First off let me say I prefer heeling while facing the building, but since you are looking for valid points against your argument, let me take a whack.
Fire service ladders are generally rated for 750 pounds. Therefore, more then 1 person can be on the ladder at once. If you have someone on the fly section of a 28' ladder and the heel man steps aside to allow another member up to help support the hose line, there will be a span of time where there is no one heeling the thing. Obviously a dangerous situation.
The heel man has a critical job while performing his task. Unless mechanical means of heeling are sought, he can not falter so long as someone is on the ladder. If he is not paying attention to the ladder, and instead, facing the building and trying to direct people, or trying to help push the hose up the ladder, he becomes a danger to those he was scheduled to protect.
These arguments are not meant to be persuasive, but I think they stand the straight face test as a sound argument.
Having seen too many ladder collapses at construction sites I wouldn't put myself under a ladder to "foot" the ladder. Ladders rarely go backwards when they collapse so now your entertaining a collapse hurting not only the firefighter on the ladder but the firefighter whom is footing it as well. Footing the ladder is just what it sounds like, FOOTing it. Relying on only arm strength is a losing battle when you have a firefighter weighing 270 pounds dressed.
I agree with Jack, that ladders should be footed in front. My only argument for footing from behind was already mentioned. I think you would have more control over sideways movement if you were behind it due to body position and body weight. Being in front and trying to stop sideways movement would be a little harder I suspect, because I don't think that you could get close enough to get the leverage it takes to stop it. Obviousely I haven't been in this situation yet, so my thoughts are just that, thoughts.
As for sliding, definately footing from the front is better, I think. More force on the foot will increase friction. Hopefully enough to stop the slipping.
As for the vid. posted, I've been on a few ladders and have footed a few ladders, and I know what it feels like. The guy "footing" the ladder in the video obviousely wasn't paying attention. He should have felt the FF still moving on the ladder. And he still could have given a quick look up to make sure. And as for glass falling in your face or eyes,. you should be wearing your goggles or have your shield in place.
I think Jack was on to something about food arriving.
This is the argument I've always heard. It keeps the "footer" out of the way of people going up and down the ladder, hoses, tools, etc. Also, you can put more force on the ladder hanging off the bottom of it than leaning against it from the front. We were taught to stand with our feet against the ladder if we were in front of it to keep it from kicking out.
I think the proper answer is that it's more stable to foot from behind the ladder, and you never need to let go. That said, sometimes it makes more sense to foot from the front, so teach both and use your head!
OK, how many of those ladder collapses at construction sites were fire service ladders, manufactured to NFPA standards, and tested annually for NFPA compliance?
I'm betting that the answer is "zero", and I don't think your example is valid for the fire service.
I've heeled ladders from the back for 35 years and in busy departments that caught a lot of fire, and I've never seen a fire service ground ladder collapse. I have seen several firefighters footing the ladder from the front get injured by firefighters slipping and falling onto them, having tools dropped on them, and being hit by the nozzle from a dropped hose line.
A ladder collapse is a rare event. Firefighters slipping or dropping tools or hose is common.
We shouldn't ignore the common hazards while protecting ourselves from rare ones.
As for strength - well, proper heeling the ladder from the back doesn't just rely on arm strength - it uses the firefighter's entire body weight to keep the ladder foot in place. The arms are just the connection point. A foot simply doesn't apply enough force to keep the ladder in place if the ladder is footed into mud, on a hard, smooth surface like concrete or asphalt, or especially on oily or icy surfaces. Firefighter weight on the ladder's back side works under all of those conditions.
I was taught both ways. I use whichever seems appropriate at the time. Most of the time it's hangiing my weight under the ladder - but I don't hold onto the rungs, too close to the heavy boots! I think tha ladder is far more secure with me under it, than it could be with my feet placed on the heels of the ladder. Stuff falling? The ladder will help there. I also keep my head still and have my visor down.
True Luke, but if he hadn't let go, I don't think the ladder would have slipped, it doesn't start sliding until the 'footer' has moved clear. Well, it probably wouldn't have started sliding if he'd had his wait on it, not simply standing there holdiing it! If it was slippery underfoot, I'd probably have stood facing the wall; if not? As I said, I'll use the method that best seems to suit the moment.
I've footed ladders between two walls where facing the wall wouldn't have been possible, too close to allow wall facing, yet too far apart to allow the ladder to be propped between the two walls.
With the foot of the ladder placed in a garden bed, or on a soft grass bed, the ladder feels far more secure to me when I'm under it. Somebody with a lot less body weight than me? Who knows, but then they also may not have the strength nor body weight to hold the ladder with their feet?
Just curious, have you actually tried your test? I'd be curious to know the results, be nice to actually have some empirical evidence one way or the other, at least in terms of actual slide resistance.
