a) tighten the nuts on the legs so they don't flop down when you pick up the stand.
b) always stand right next to the stand with one foot on one of the legs.
c) rope and tent stakes.
d) 5lbs or 10lbs weight over the shaft. Depending on how much gear you like to lug around.
e) anything you clamp to it, pad with some of that kitchen drawer stuff or a sock / rag. No reason, just extra padding when it falls over I guess.
f) if using a boom arm keep the weight centered. Which might mean hanging a shoe or sweater off the other end. Pick up the stand about 1/3 to 1/2 of the way down, if it tips, your weight is not centered.
g) only place the stand on level ground.
h) always keep the stand at it's MINIMUM extension. Or be prepared to be your stands battle buddy. i.e. foot on leg, hand on stand, never more than 2' from it.
i) use a shock mount so something other than your mic might hit the ground first.
j) rope, weights, stakes, and more rope, weights, and stakes.
