Written by Lock + Store | Sep 22, 2025 4:11:08 AM

Self-storage units are an excellent way to free up space, organise your belongings, and keep items safe. However, there are certain things that are strictly prohibited, unsafe, or simply unwise to store in a self-storage facility. Understanding what not to store helps ensure that your belongings – and everyone’s safety – are protected.

In this guide, we’ll cover the key items you should avoid storing in your self-storage unit, including a reminder that vapes are not permitted.

Lock+Store adopts the Self Storage Association Asia guidelines on responsible storage. When in doubt, you can refer to the posters displayed prominently at our facilities or speak to our storage specialists.

 

Items You Should Never Store in a Storage Unit

 

1. Perishable Food and Beverages

Storing food or drinks can attract pests like rats, cockroaches, or mold, which could spread to other stored items and cause health hazards. Most facilities have strict policies against food storage – so avoid this altogether.

2. Flammable and Explosive Materials

This includes gasoline, kerosene, propane tanks, fireworks, and any other flammable liquids or gases. These pose significant fire risks and are illegal to store in any self-storage unit. Most facilities require a strict ban on these for everyone's safety.

3. Hazardous and Toxic Materials

Chemicals such as bleach, acids, pesticides, batteries, or cleaning agents should never be stored. These substances are dangerous, and improper storage can lead to leaks, fires, or chemical reactions.

4. Valuables and Sensitive Items

While Lock+Store offers insurance options, avoid storing valuables such as branded handbags, artworks, haut couture or irreplaceable items.

Items That Are Strictly Prohibited

5. Vapes and E-Cigarettes

Vaping and vapes are strictly banned from self-storage units. They are not only illegal, but may also contain batteries, liquids, or cartridges that pose fire and chemical hazards. Facilities comply with local laws and regulations, and storing vapes is considered unsafe and prohibited. Always dispose of them responsibly through proper recycling or waste channels. The Health Sciences Authority has published a list of avenues to surrender e-vaporisers

6. Illegal Substances

Any illegal drugs or substances are strictly forbidden and can lead to criminal charges. Do not attempt to store any illegal items.

7. Animals and Living Creatures

Self-storage units are not pet or animal shelters. Do not store living animals, plants, or biological specimens.

8. Medical Waste

Sharps, contaminated bandages, or medical waste are hazardous and prohibited. Proper disposal through healthcare providers is required.

By following these guidelines, you’ll ensure your belongings are stored responsibly, safely, and within the regulations. Whether you’re storing seasonal items, furniture, or important documents, responsible storage benefits everyone – yourself included!
