Airline Safety Southwest's Battle Against Exploding Soda Cans in Extreme Heat - Southwest's unique beverage management practices

Southwest Airlines is facing a unique challenge related to its beverage management practices during periods of intense heat. Numerous reports have surfaced regarding exploding soda cans onboard their flights, a problem that appears to be more prevalent with Southwest than other carriers. The issue has resulted in a concerning number of injuries among flight attendants, primarily due to the unexpected force of the bursting cans. This has understandably led to safety concerns, especially as the summer heat continues.

In response to these incidents, Southwest has begun implementing changes aimed at keeping beverages cooler during flights. This includes a collaborative effort with the Union's Safety Team to evaluate the effectiveness of these measures, which will involve regular data analysis. The exploding can incidents highlight an unforeseen risk associated with standard onboard service, prompting a closer look at Southwest's current approach to managing beverage storage and service protocols. Whether these new procedures will sufficiently address the problem remains to be seen, as the potential for explosive cans persists in the current climate.

Southwest's approach to beverage management appears to be at the heart of this unusual issue. They've acknowledged a connection between their practices and the higher-than-average number of exploding soda cans, which is a curious finding. It seems they've been freezing certain drinks to combat the problem, suggesting they've been dealing with this for a while. It makes sense to keep beverages cooler in the cargo hold, but their specific loading methods may play a role here. It's also intriguing that they use specialized cans to deal with the lower air pressure at cruising altitudes, but evidently, extreme heat can push these beyond their design limits.


The fact that a single can of beer can build up so much pressure under extreme heat reveals how tricky this problem is. Monitoring temperatures with sensors is a sensible approach to mitigation. While pre-chilling before loading seems logical, the heat conditions encountered in the cargo bays and cabins are clearly creating challenges, even with this method.

The way Southwest manages its beverage selection suggests that they're trying to optimize the supply chain for efficiency. However, it raises a question whether there are other, less-popular beverages, or a combination of drinks, that experience the exploding can phenomenon more often than others, maybe due to unique packaging and compositions. Their process of stress testing cans is important, but it's clear that the extreme environment of airline cargo and cabins has outpaced their design parameters, especially in these hot summers.

Keeping drinks cooler than what you'd find on the ground during service is a clever idea to help with pressure issues. The meticulous tracking of expiration dates is undoubtedly part of their overall safety protocol. However, it seems this is mainly linked to the quality of the drinks and not directly addressing the explosion risk in a more proactive manner. Perhaps a deeper dive into the design and material characteristics of various canned beverages, and especially how they're specifically affected during cargo transport on Southwest planes, will provide answers.

Airline Safety Southwest's Battle Against Exploding Soda Cans in Extreme Heat - The science behind exploding soda cans in extreme heat

The reason behind exploding soda cans in extreme heat is a simple matter of physics: increasing pressure. As the temperature rises, the gas inside the can expands, pushing against the internal walls with ever-growing force. In the enclosed space of an aircraft cabin, this pressure can build to a point where the can's structure simply cannot withstand it anymore, resulting in a sudden burst. Southwest Airlines has seen a significant surge in these explosions, particularly in recent summers, leading to injuries for crew members, and a call for better measures to control onboard beverage temperatures. This raises concerns about the ability of standard beverage packaging to withstand the extreme conditions encountered during air travel, especially in the face of a changing climate. The situation highlights the need for airlines to reevaluate their handling and storage procedures, recognizing the potentially serious consequences of such incidents. As temperatures continue to rise, this previously unforeseen safety concern could become more common across the industry.

The science behind exploding soda cans in extreme heat is a fascinating blend of physics and materials science. Cans are designed to withstand a certain pressure range, typically around 2.5 to 3 atmospheres. However, when exposed to temperatures exceeding 120°F, the internal pressure can skyrocket to over 4 atmospheres, leading to a violent burst.

The composition of the soda itself plays a role. Sugars and minerals in these beverages tend to absorb heat readily, creating a higher vapor pressure within the can. This is further compounded by the basic principle of thermal expansion: liquids expand when heated, which in the case of soda can rapidly increase pressure inside the sealed can.

Aluminum cans, while robust, are not impervious to the effects of extreme heat. Elevated temperatures can weaken the can's structure, causing it to fail at lower pressures than intended in its design. The phenomenon of dissolved carbon dioxide in carbonated beverages adds another dimension. When heated, the gas expands rapidly, and if the temperature rise is swift, it may not have time to re-dissolve. This can result in an explosive release of pressure as the can's integrity fails.

The unique environment of an aircraft further complicates things. Cabin pressurization, while essential for passenger comfort, places stress on the can's material. When combined with high temperatures, this stress can amplify the risk of explosive decompression.

Although safety standards for beverage cans involve rigorous testing, including pressure tests under various temperatures, they may not fully capture the extreme variability of conditions found in airline cargo holds. These areas can get incredibly hot, especially during extended periods of ground time on hot summer days.


The volume of liquid within a standard soda can, roughly 355 mL, becomes an issue when considering temperature changes. The vapor pressure created from the heat can easily exceed the initial liquid volume, creating immense internal pressure within the can.


Another factor is the thermal conductivity of aluminum, the primary material for soda cans. The rate at which aluminum dissipates heat determines how quickly the can reaches dangerous internal temperatures. Limited airflow or cooling in places like airplane cargo holds, particularly on hot days, can exacerbate this risk.

While keeping sodas chilled helps mitigate the issue, perhaps a more proactive approach involves real-time temperature monitoring equipment within cargo areas. This could provide valuable data, leading to better predictive models and insights into how to further mitigate this potentially dangerous issue. Continuous improvements in safety practices are always important to maintain, and further research into how the interplay of factors like temperature, pressure and container material interacts is vital to understanding this phenomenon.

It's noteworthy that the pressure buildup within a single can under extreme heat can reach significant levels. Southwest's existing approach to cooling beverages, including pre-chilling, may not fully counteract the extreme conditions within the cargo bays and cabins. It's unclear whether this is primarily due to a specific beverage composition or the methods of transport.

Examining the material properties and design parameters of various beverage containers is crucial for understanding this issue. It's plausible that the design limitations of standard cans, especially in extreme heat, have been exceeded, particularly within the confines of an aircraft environment. Additionally, it is interesting to consider whether there are particular beverage types more susceptible to exploding due to their ingredients or packaging.

While Southwest's procedures for monitoring expiration dates and maintaining drink quality are important, they seem to address drink quality rather than directly tackling the core problem of potential explosions. This incident sheds light on the challenges of ensuring passenger and crew safety in the face of ever-increasing external environmental factors. Further investigation into the interplay of material science, temperature fluctuations, and container design within the aircraft environment could potentially uncover strategies to mitigate this emerging safety risk.
