Aerosol cans have long been widely used in the fields of home, industry and personal care, and how to store these aerosol canisters safely has become an issue that cannot be ignored. Improper storage of aerosol cans may lead to risks such as damage, leakage, and even explosion of the cans.
Understanding and choosing the appropriate storage location is the key to ensuring a safe home and work environment. This article will analyze the characteristics of aerosol canisters in detail and analyze the best storage location from multiple angles.
Why is the storage location of aerosol cans so important?
Why does the pressure of aerosol cans affect the storage location?
Aerosol cans are high-pressure containers, and the propellants and contents filled inside are usually gaseous or liquid chemicals that can be released through a nozzle at appropriate pressure. This high-pressure characteristic means that aerosol tin cans are susceptible to changes in ambient temperature, and rising temperatures may cause a sudden increase in pressure inside the can. If the storage location is exposed to direct sunlight or the temperature is high, the increase in pressure inside the can may cause the can to expand or even rupture. Therefore, the storage location of aerosol tin cans should avoid high temperatures and ensure a relatively constant environment to ensure the safety of long-term storage.
Why do you need to avoid being close to fire sources?
The propellants in aerosol cans are usually flammable chemicals, such as propane, butane or liquefied gas, which will burn rapidly or even cause explosions when exposed to fire. Even some seemingly harmless aerosol cans may contain chemical components that will increase the risk of fire if they spontaneously ignite or evaporate when the temperature rises. Therefore, when choosing a location to store aerosol tin cans, it is a key principle to keep them away from fire sources as much as possible.
Do you need to consider the temperature when storing aerosol canisters?
What is the ideal temperature range?
The optimal storage temperature for aerosol canisters is usually between 15 and 25 degrees Celsius. This range allows the can to maintain a stable internal pressure and avoid expansion and rupture due to high temperatures or condensation of the contents due to low temperatures. When the temperature difference between winter and summer is large, special attention should be paid to the location where the aerosol canisters are stored. For example, do not place aerosol cans near heating in winter, and avoid placing them in direct sunlight in summer. In addition, some common heating pipes and water heaters in homes, areas with high temperatures or periodic temperature changes are also not suitable for storing aerosol tin cans.
Is it suitable to store aerosol cans outdoors?
The temperature in the outdoor environment varies greatly. The sun exposure during the day and the cooling at night may cause the aerosol canisters to experience frequent high and low temperature alternations, which has a significant impact on its internal pressure. Especially in summer, the outdoor temperature may exceed 40 degrees Celsius, and the fluctuation of the pressure in the can is very likely to cause leakage or explosion risks. Therefore, it is more ideal to store aerosol canisters in a constant temperature environment indoors to ensure that the temperature is stable and not affected by the external climate.
Is it safer to store aerosol cans in ventilated areas?
Why is a ventilated area more suitable for aerosol can storage?
The propellant or contents inside the aerosol can may leak slightly, and even an unopened can may evaporate a small amount after being placed for a long time. These gases are easy to gather in a confined space, and if they encounter sparks or ignition sources, they may cause combustion. Therefore, a well-ventilated environment is more conducive to the diffusion and dissipation of volatile gases, avoiding accumulation in a confined space and causing fire hazards. Storing in a well-ventilated location can significantly improve the storage safety of aerosol tin cans.
What risks does a poorly ventilated storage location bring?
Poorly ventilated areas, such as basements and storage rooms, have poor air circulation. If an aerosol can leaks, the gas will accumulate in this space. Once someone turns on a light switch, uses an electronic device, or generates a spark in this area, it may cause a deflagration. Therefore, when choosing a location to store aerosol tin cans, you should ensure air circulation and avoid being airtight, especially in residential spaces, and avoid placing aerosol tin cans in small, enclosed spaces.
Are aerosol cans suitable for storage in high places?
Why should you avoid storing aerosol cans in high places?
Aerosol cans are light in themselves. If placed in high places, they may fall due to accidental collisions, vibrations, or other factors, causing damage to the can body, loose nozzles, or even rupture of the can body. When an aerosol can falls, the internal pressure may cause damage to the can body or even accidental spraying. Therefore, when storing aerosol tin cans, try to avoid placing them above the human shoulder. It is safer to choose a stable and safe ground or low platform as the storage location.
Can aerosol cans be placed on shelves?
Shelves can be used to place aerosol cans, but it must be ensured that the shelves are stable and not easy to tip over, and there are no people or objects that move frequently in the area below the shelves. If the shelves are not stable enough, the aerosol canisters may fall due to external shaking, causing damage to the cans. In addition, for safety reasons, try to choose shelves with fences or protective designs to prevent aerosol cans from rolling down.
Can aerosol cans be stored in the car?
What are the risks of storing aerosol cans in the car?
The interior space of the vehicle is relatively closed, and the temperature is easy to rise after being exposed to sunlight. Especially in summer, the temperature in the car can quickly reach more than 50 degrees Celsius, significantly increasing the risk of aerosol tin cans bursting. In addition, the driving and bumps of the vehicle may cause vibration and compression to the aerosol can body, further increasing the risk of damage to the can body. If the aerosol can breaks in the car, the released gas may cause suffocation, dizziness, and even fire to the people in the car. Therefore, it is not recommended to place aerosol tin cans in the car for a long time.
How to ensure the safety of aerosol cans in the car?
If you must carry aerosol cans in certain circumstances, such as outdoor activities or emergency situations, it is recommended to store the aerosol canisters in the trunk of the vehicle and avoid exposure to direct sunlight. Try to take out the aerosol tin cans after arriving at your destination to avoid long-term storage in the car. At the same time, use a sun visor or other shading objects to block it and try to keep the temperature in the car constant.
What other precautions should be taken when storing aerosol cans?
Can different types of aerosol tin cans be stored together?
Different types of aerosol tin cans may contain chemicals of different components, and some chemical components may react with each other. Therefore, it is recommended to avoid storing aerosol tin cans with different contents together, especially to avoid placing flammable and explosive items in one place. If necessary, different types of aerosol canisters can be stored separately with partitions to ensure that different contents do not affect each other and ensure the safety of the storage area.
How to ensure that the aerosol can body is intact?
Before storing the aerosol can, the appearance of the can body should be checked to ensure that there is no deformation, rust, loose nozzle, etc. If the can body has been aged or corroded, it should be stored with caution or handled in accordance with relevant regulations. Keep the aerosol can away from corrosive substances (such as detergents, acid chemicals, etc.) to prevent the aerosol can from accelerating aging or corrosion due to contact with chemicals.
