MSR fuel canisters are a popular choice for backpacking, camping, and mountaineering because they’re lightweight, efficient, and reliable. However, because they contain pressurized flammable gas, proper storage is essential for safety, performance, and longevity. This article explains best practices for storing MSR fuel canisters at home, during travel, and in the field.
Understanding MSR Fuel Canisters
Most MSR fuel canisters contain a blend of isobutane and propane, stored under pressure in a sealed metal container. These canisters are designed to be durable, but they are still sensitive to heat, puncture, and misuse. Proper storage helps prevent leaks, ruptures, and reduced fuel performance.
General Storage Principles
No matter where you store your MSR fuel canisters, follow these basic rules:
- Store in a cool, dry place
- Keep away from direct sunlight and heat sources
- Avoid puncturing, crushing, or modifying the canister
- Store upright whenever possible
- Keep out of reach of children and pets
Storing MSR Fuel Canisters at Home
When storing canisters at home—whether short-term or long-term—consider the following guidelines:
Temperature Control
- Ideal storage temperature is below 120°F (49°C).
- Avoid locations like attics, cars, or near heaters where temperatures can spike.
- A garage or gear closet is acceptable as long as it stays cool and well-ventilated.
Ventilation
- Store canisters in a well-ventilated area.
- Never store large quantities in enclosed, unventilated spaces.
Organization
- Keep canisters away from sharp tools or heavy objects that could dent or puncture them.
- Label partially used canisters so you know their fuel status before trips.
Storing Canisters During Travel
In a Vehicle
- Do not leave fuel canisters in a parked car for extended periods, especially in warm weather.
- If transporting by car, keep canisters shaded and remove them as soon as you reach your destination.
Air Travel
- MSR fuel canisters are not allowed on airplanes, whether full or empty.
- Do not attempt to clean or declare them as empty—airlines prohibit them entirely.
- Plan to purchase fuel at your destination.
Storing MSR Fuel Canisters in the Field
While camping or backpacking:
- Store canisters away from campfires, stoves, and other heat sources.
- Keep them shaded during the day to avoid pressure buildup.
- In cold conditions, store canisters inside a pack or sleeping bag (not in use) to maintain fuel pressure—but never place them near open flames.
Long-Term Storage Considerations
MSR fuel canisters have a long shelf life when stored properly.
- Check periodically for rust, dents, or valve damage.
- Light surface rust is usually cosmetic, but deep corrosion is a reason to dispose of the canister.
- There’s no need to empty a canister before storage unless it’s damaged.
What Not to Do
Avoid these common mistakes:
- Do not expose canisters to open flames or extreme heat
- Do not store near sparks, pilot lights, or electrical equipment
- Do not puncture or attempt to refill disposable canisters
- Do not dispose of canisters in household trash unless they are fully empty and local regulations allow it
Disposal and Recycling
When a canister is completely empty:
- Confirm it releases no gas when the valve is pressed.
- Follow local recycling rules—some areas require puncturing with an approved tool before recycling.
- Never incinerate fuel canisters.
Check MSR’s official guidance or your local waste authority for the most accurate disposal instructions.
Conclusion
Storing MSR fuel canisters properly is simple but critical. By keeping them cool, dry, and away from heat or damage, you ensure safe operation and reliable performance on every trip. Whether at home, on the road, or in the backcountry, responsible storage protects both you and your gear.
