Never store your inventory in an outdoor storage shed near the neighbors backyard fire pit. Depending on which way the wind blows the contents might absorb the smoky scent. (Happened to a friend).
Never store your inventory in cardboard boxes in your garage. Gasoline and oil smells as well as cut grass clinging to the lawn mower and moisture from humidity can permeate the boxes. Black mold and mildew can be an issue.
Wherever your inventory is stored add a smoke detector and fire extinguisher nearby. Lightening might strike, an electrical fire or spontaneous combustion might occur putting you out of business.
Keep your inventory off the floor unless it's water friendly. Basement floors can be damp or slightly damp, not to mention that icky mold creeping in corners.
Keep scented items no matter how well they are sealed and in storage containers far away from everything else. A no-brainer but worth mentioning.
Sharp items or those with rough edges should be positioned so you don't grab them and injure yourself. Keep up with your tetanus shots just in case.
Tall stacks of boxed treasures can fall on you causing damage to you and the aforementioned treasures.
Lift with your legs, not with your back leaning over.
Anyone care to add to the list?
