Is It Safe to Store Iwatani Gas Canisters in a Car?

It is unsafe to store portable stove gas canisters in a car. These canisters contain flammable and explosive fuel, with instructions specifying that storage temperatures should not exceed 40°C. During summer, temperatures inside a vehicle can exceed 60°C, which may easily cause the gas canisters to explode or combust. Safety Precautions for Portable Stove Gas Canisters: Definition of Portable Stove: Portable stoves, also known as butane gas stoves, are non-fixed cooking appliances that primarily use butane gas as fuel (liquefied petroleum gas can also be used) and employ direct flame heating. They are commonly used for outdoor family recreation and as hotel supplies. Pressure Sensing Mechanism: Most portable stoves utilize a pressure-sensing system via a regulating valve that monitors pressure in both the valve body and gas canister. The system triggers corresponding actions by the anti-explosion rod inside the regulating valve when pressure fluctuates. Without this pressure-regulating and explosion-proof device, excessive pressure in the canister and valve could lead to explosions. When equipped with safety mechanisms, the anti-explosion rod will activate under high-pressure conditions by either engaging the canister lever or cutting off the gas inlet/outlet to isolate gas flow, thereby preventing further pressure buildup and potential hazards.
As someone who frequently goes camping, I can share my experience: it's very risky to leave Iwatani gas canisters in the car, especially during summer when exposed to direct sunlight. Last year, I forgot a canister on the back seat when my car was parked outdoors, and the temperature soared, causing the canister to expand and nearly leak. Fortunately, I noticed it early, and nothing bad happened. Typically, car interiors can heat up to over 50°C. Since gas canisters contain compressed gas, high temperatures can cause a dramatic increase in pressure, raising the risk of explosion. For safety, it's best not to leave them inside the cabin. If you must carry them, store them in the trunk, wrapped in insulating material to avoid direct sunlight. I recommend developing a habit of checking the car before getting out and removing flammable items. After all, safety comes first—don’t risk big trouble for small conveniences.
