This is in some ways a confusing topic...
I think we need to get our terminology straight. Newer style chippers with a set of feed rollers are totally different from older style chuck n ducks. Newer chippers also have a lot more safety features. In australia, OHS specifies that there be a minimum distance of 1m from the feed rollers to the end of the "no entrace' area, then a further 1m chute beyond that adding up to 2m, or nearly 7'.
We run a bandit 18, it could chew me up no problem but I feel it's a fairly safe machine when operated correctly. The most common injuries when chipping have nothing to do with the operator going through the chipper which is very rare (but does happen). Most injuries are related to crushes - operator getting squashed by a log as the feed rollers take it up, bruises/fractures when logs suddenly swing sideways, and then lesser injuries like chunks spitting out at you when someone lifted the rollers up or you ended up with crap in your eye.
Using your foot is not a complete no no. There are times when it is safer.... most often when feeding logs that are over 3' long, but large and heavy. I'd rather have 2 hands on the over bar, one foot on the ground and one foot pushing the log then have 2 feet on the ground and trying to push by hand. You can generate a lot more push with your feet, and in a safer way too. Good luck trying to push a 4 or 5' 18" log by hand into the chute. Especially if it's a wet heavy hardwood. I'd love to have a vide of someone trying to push same into chute by means of a push paddle.
To me, safe chipper operation starts at limbing time. Cutting pieces in a way that they will feed through the chipper easily and have no forks for at least the first 2' is a great start. Proper stacking is the next step. Beyond that, proper 'sequencing' of feeding the chipper - ie. as you feed, peel off to the outside. Never feed from the middle. The next man in line feeds from the inside, never trapping the previous man. Running big chippers, we sometimes have 6 men feeding and can punch out 40 yards in an hour if it is well cut and stacked. Keeping the area in front of the chipper clear is important.
Then after that is not ever putting any part of your body past the 'fold line' of the chipper - the part of the chute that folds, about 1m away from the rollers. We use push paddles on short pieces, or more commonly other branches. Then after that, is using hands vs feet. There are plently of times when using a foot is appropriate, and safer.

Have to see to believe it. Yet to all his own. Coming from you I give it more merit. (Foot in the chipper)
The story go's
two climbers hear the chipper not being loaded as its running. They find Jose has been precessed. A car drove by and noticed him, I believe, standing on the loading chute and kicking brush in.:msp_ohmy:
Foot in the chipper?? 12" chuck and duck man eater will get that habit cured. Still the fastest thing out there
