I dont know how to lead into what I have to say here without demeaning the other posters but damn guys,, this fellow leads off with his shop is full of saw dust and he is using a torch in same building???? Believe me I am no safety freak but you are not over thinking this deal, you are underthinking.
Your concerns at this point does not need to be long term storage of your torch set but in being certain that you remove anything stored in your shop that is irreplaceable and that you keep the fire insurance paid up,,,, because your going to need it!
STOP! using a torch inside of that building until your housecleaning habits, as they pertain to sawdust, improve. Until then use the torch outside at least 20' from the doorway and dont leave the area or building until at least 15 minutes have passed since you quit using the torch and even then take a good look and sniff around for smoldering wood before you leave.
That's my advise and speaking from experiance,,,
