Double-Check: It’s Hazardous to Store These 9 Materials in Your Self-Storage Unit

While self-storage is the best way to get unnecessary items out of your house or garage, there are some things that are always unwelcome. When considering what not to store in storage units, you have to think about hazardous materials and items that simply aren’t safe to have in a public place. As you plan what to store, remember that a self storage unit is a public place. These are some limitations and unacceptable items that you need to bear in mind.

Dangerous Chemicals or Toxic Materials

There are some items that you simply can’t put in a storage unit because of the extreme conditions. With smoldering or freezing temperatures and enclosed spaces, you just don’t want to store some combustible, flammable, hazardous or toxic items. These may include gasoline, compressed gas, kerosene, lamp and motor oil, grease, acid, corrosives, fertilizer, paint, cleaners, chemicals, narcotics cleaners, propane tanks, biological waste, toxic waste, or products containing asbestos. 

Don’t Store Any Kind of Weapons

Storage units are not a place to keep an arsenal, but most self-storage facilities don’t allow you to even store fireworks as they are considered to be explosive. Most weapons and ammunition aren’t allowed. Explosives and other potentially threatening weapons are typically listed as prohibited in the terms of use policy.

Live animals and pets

This one is crazy. After all, who would want to leave a live animal in their storage unit? Strangely enough, people have done it. Leaving a live animal in a self-storage unit is not only against public storage restrictions, it is against the law. Don’t ever do it!


As you well know, plants need light, water and fresh air to grow. These three essentials cannot be found inside in a storage unit.


Most food items cannot be stored in storage facilities, whether they are climate controlled or not. Canned foods are typically allowed in climate controlled storage units, but you won’t be able to store meats, dairy products, cereals, produce, or other perishables. The main reason? It all attracts nasty pests.

Scented or Wet Items

Strong scents can easily attract pests, insects, rodents or vermin to investigate the source of the overwhelming odors. Trust us, you don’t want any living things crawling or flying around in your storage unit as that will spell out T-R-O-U-B-L-E in no time.

Also, any items that are wet or damp will start producing mold or mildew and spread bacteria in your affordable storage unit. This will likely damage some, most, or all of your prized possessions placed in temporary storage. First and foremost, make sure that every single item you plan to store is perfectly dry before you pack it up and leave it in your storage unit.

Animal Products

As with human food, you shouldn’t store animal food as it will perish and possibly attract pests to your storage unit. This includes bagged pet food, treats, rawhide, and other items that can easily spoil in extreme weather conditions.


This may seem obvious, but garbage belongs in the dumpster. Trash attracts bugs and vermin – plus, it’ll stink up the place.

Miscellaneous Things

You cannot plug in any electric items for storing other items. For example, you wouldn’t be able to plug in a freezer to store meat. You also can’t store generators, space heaters, or live in a storage unit.

While there are a ton of restrictions on what you can’t store in a storage unit, this is mostly for your protection and the protection of your valuables. You definitely don’t want something happening to you or your storage unit neighbor’s items simply because you weren’t careful.For safely storing your belongings in the Jackson, Tennessee area, contact the professionals at Markham Self Storage.
