I would think that through a bit:

"Note that even the smallest trace of moisture may result in a steam explosion, spattering burning molten metal around."

I think sand would be a better alternative, but a few hundred lbs. of solder on a RT floor won't go far before it freezes.

Have a CO2 fire extinguisher handy to solidify i.e. freeze -100 degF the moving molten metal mass.  

Just a thought

Ho!
Too right.
I offer to the advice pile:
Attend to your PPE; specifically don't wear synthetic fabrics/footwear when messing with molten metal. 
Do wear proper gloves, appropriate eye protection. 
Don't trust drain valves; especially don't trust electric drain valves. They easily jam open.
[Think about how far molten solder will spread and how far /fast you will need to go to keep ahead of spilling metal. Further /faster than you ever thought possible in both instances :)] With used/unknown equipment make sure everything is dry and free of anything volatile. You don't want an "Old Faithfull" experience. 
I thought we already addressed the top up issue, at least theoretically in an earlier go round: subject to analysis you could leave the SAC in there.
Of course a few hundred pounds of SAC is worth a lot more pounds of Sn/PB and can be traded to reduce fill cost. This would be lost if you left it in machine.

Best Wishes

I had a runaway pot in Thailand on a Select Machine.
Pot drained and insides fried.
Not pretty and expensive to fix.
Manufacturer put in redundant sensor after that.

Read the manufactures instructions and ask them questions.
I had a Tech tell me that I couldn't be an Engineer because I cheated, I read the instructions first.

Electronics uses benign equipment for the most part.
European guarding and few high kinetic parts.
Solder pots and the insides of the turret machines can crush, burn or kill.
Even the Sr Tech had solder splash on his face doing routine maintenance.
Wear eye protection at a minimum.
Engineers and techs are notorious for skating on safety to check something out.
Typically the solder guys have a few scars from inadvertent touches with something hot whether solder pallets, pots or solder.
