What to Do with Old Propane Tanks During Spring Cleaning
Spring cleaning often uncovers old propane tanks, aerosol cans, and camping fuel canisters hiding in garages, sheds, and storage bins. These items should never go in the garbage or curbside recycling bin. Because they are pressurized containers, they can cause fires, explosions, and serious safety risks if crushed or punctured during collection and processing. In Ontario, pressurized containers must be handled separately and taken to approved drop-off locations for safe recycling or disposal. This guide explains what counts as a pressurized container, why these items are hazardous, and where to take them so you can clean out your space safely and responsibly.
What Counts as a Pressurized Container?
Pressurized containers are sealed containers that hold gas under pressure. Even when they appear empty, many still contain leftover gas or vapour that can create safety risks if damaged or disposed of incorrectly.
Common examples include:
- BBQ propane tanks
- Small propane cylinders used for camping
- Butane fuel canisters
- Aerosol cans such as spray paint and cleaners
- Portable fuel containers used for outdoor equipment
These items are grouped together because they all contain compressed gases or flammable contents. During spring cleaning, they are often found stored in garages, sheds, basements, workshops, and camping gear bins where they may have been sitting for years.
Many people assume an “empty” container is safe to throw away. However, even nearly empty propane tanks and aerosol cans can still contain enough residual gas to ignite if punctured or crushed. That is why pressurized containers require special handling and should never be placed loosely in household garbage or recycling.
If you are unsure whether an item is considered pressurized, review the pressurized containers recycling guide.Why Old Propane Tanks and Aerosol Cans are Hazardous
Old propane tanks and aerosol cans create serious safety hazards because they contain pressurized gases and flammable materials. When these containers are crushed, punctured, or exposed to heat, they can ignite or explode.
This risk becomes especially dangerous in garbage trucks and recycling facilities where materials are compacted under high pressure. Even a small amount of leftover gas inside a tank or aerosol container may be enough to start a fire. Fires caused by improperly discarded pressurized containers can damage equipment, interrupt recycling operations, and put workers at risk.
Many propane cylinders and aerosol containers may also retain residual contents long after they appear empty. Because of this, these items should never be punctured, dismantled, or intentionally emptied at home.
Ontario’s Blue Box recycling system accepts many empty aerosol containers, including food sprays, hairspray, air fresheners, shaving cream, and deodorant cans. Containers should be completely empty and recycled with lids on. Aerosol products that still contain contents should not be placed in recycling, and toxic or corrosive aerosol products that are not part of accepted consumer packaging streams require separate handling and disposal.
Understanding these risks helps protect collection workers, recycling facilities, and local communities, while proper sorting helps reduce fires, contamination, and operational disruptions.
Spring Cleaning Scenarios: Where These Items Show Up
Pressurized containers are easy to forget about because they are often stored for long periods of time.
During garage cleanouts, people frequently discover:
- Old BBQ propane tanks
- Rusted propane cylinders
- Small camping fuel canisters
- Unused workshop sprays
Sheds and outdoor storage spaces are another common source of hazardous items during spring cleaning. Aerosol pesticides, spray paint, lubricants, and lawn care products often sit unused for years.
Camping season also brings attention to leftover fuel canisters from previous trips. Small propane cylinders and butane canisters are commonly packed away after summer and forgotten until the next outdoor season begins. In Ontario, these containers can be safely managed through the OrangeCycle program, which provides designated collection cages at many provincial parks to help campers properly dispose of small propane and butane canisters before leaving the campsite.
Moving, downsizing, and renovating are also common situations where people uncover old pressurized containers they no longer need.
Because these items may degrade over time, it is important not to stockpile them indefinitely. Older tanks and damaged containers can become more dangerous if exposed to heat, corrosion, or physical damage.
Before throwing anything out, review these common recycling mistakes to avoid so hazardous materials stay out of regular waste streams.
What to Do with Old Propane Tanks in Ontario
If you find an old propane tank during spring cleaning, the safest option is to take it to an approved recycling or hazardous waste drop-off location.
Here is what to do:
1. Do not place propane tanks in garbage or recycling bins
Propane tanks should never go in household garbage, curbside recycling, or scrap metal bins. Pressurized tanks can explode if crushed during collection or processing.
2. Never puncture or dismantle the tank yourself
Do not attempt to release remaining gas or cut open the container. Even nearly empty tanks may still contain flammable vapours.
3. Keep the tank upright and intact
Store propane tanks in a cool, ventilated area away from heat sources, sparks, or open flames until you are ready to transport them.
4. Identify the type of container
Some propane tanks are refillable, while others are designed for single use. Both require proper recycling or hazardous waste handling.
5. Transport the tank safely
When transporting propane tanks:
- Keep them upright
- Secure them so they cannot roll around
- Avoid leaving them in a hot vehicle for long periods
6. Take them to an approved drop-off location
Ontario residents can access municipal hazardous waste depots, participating retail locations, and specialized recycling programs that safely handle pressurized containers.
Programs such as OrangeCycle help improve collection access for single-use propane canisters and other pressurized materials across Ontario.

Aerosol Can Disposal in Ontario: What You Need to Know
Aerosol can disposal in Ontario depends on whether the container is completely empty or still contains product.
Examples of aerosol containers that should not be recycled in your residential blue box include:- Cleaning sprays
- Spray paint
Ontario recycling guidance identifies empty aerosol containers as recyclable metal containers when fully empty and properly prepared. However, partially full aerosol cans should be treated as hazardous waste because they still contain pressurized contents.
If you are unsure whether a can is truly empty, treat it as hazardous and bring it to a proper collection location.
Never:
- Puncture aerosol cans
- Crush them intentionally
- Burn them
- Place partially full cans in curbside recycling
Even small amounts of leftover product can create fire hazards during collection and processing.
Because recycling programs may vary slightly depending on the material and condition of the container, it is important to follow verified Ontario guidance when disposing of aerosol products.

How to Dispose of Camping Fuel Canisters Safely
Camping fuel canisters should be handled with the same care as larger propane tanks.
Common camping fuel containers include:
- Small propane cylinders
- Butane canisters
- Mixed-fuel camping cartridges
These containers remain pressurized even after use and can become dangerous if crushed, punctured, or exposed to heat.
If you are preparing camping gear for spring or summer, check for leftover canisters from previous trips. Store them in a cool, ventilated area until they can be taken to an approved collection site.
Do not:- Crush canisters
- Attempt to puncture them
- Throw them into household garbage or recycling
Ontario’s growing outdoor recreation sector has increased the need for safe recycling programs that handle single-use fuel canisters properly.
Programs like the OrangeCycle recycling program help support safer collection and recycling for outdoor recreation materials.
Where to Take Old Propane Tanks and Aerosol Cans
If you are wondering where to take old propane tanks in Ontario, several safe disposal options are available.
Approved collection options may include:
