Please provide this, or some appropriate rewording of as you see fit, to all of your people who are intending to work in relevant areas such as logistics, tech, artshow, maybe even food ... anywhere it applies. Important points to keep in mind while handling Arisia and rented property.
Don't push wagons/carts over any bumps from behind. That includes elevator door cracks, truck ramps and door lip areas, or any other obstacle that would significantly impede a wheel rolling over it. Some of the casters are fairly small and when you hit them with the full weight of the box behind and above it, they undergo *titanic* forces that can easily break them. Rather, get in front of the object and pull, slightly unweighting it over the bump. Even if you can't lift it completely off, the change in forces makes a huge difference. The smaller the wheels, the more this matters.
Do not roll wagons over any cables or wires, especially in the tech areas. Some of the cables are somewhat fragile, and wheels put a lot of pounds per square inch on the floor. We will have some protective "ramps" deployed here and there, but be prepared to lift each end over cable paths regardless.
If you're about to roll something on wheels with a sturdy flat upper surface, stack something else headed to the same area on top first! Work smarter, not harder. Note that "same area" is relative, as you could be headed toward a general staging area rather than a specific con function space.
Be aware of "smart wheels" that turn vs. "dumb wheels" that don't, and try to run wagons with different sets at each end smart-wheels-forward like a car would roll.
Two-wheel hand trucks work better when pulled, rather than pushed. It helps to be comfortable with walking backwards, of course. [*Note: the tires in all of ours that I could find have been pumped up.]
In sloppy weather, allocate "inside" versus "outside" personnel and hand objects off at the boundary, to avoid tracking dirt and wet into trucks and onto our stuff. The "inside" folks keep their feet dry so hopping up on top of loaded gear doesn't bring up all the salt and sand too. Keep outdoor working surfaces shoveled/swept off as necessary.
If, and only IF, a truck driver wants some guidance for backing, ONE person provides it. Six people yelling conflicting directions doesn't help at all.

Oh, and try to stretch out a bit before you work!
