Understanding the Unfeasibility of Refilling Oxygen Using Fire Extinguisher Cylinders

The idea of repurposing fire extinguisher cylinders to refill oxygen might seem appealing in a time of need. However, it is fundamentally unfeasible due to the inherent design and functionality of these cylinders. In this article, we will explore why this method is not recommended and discuss the potential dangers involved.

Design and Function of Fire Extinguisher Cylinders

Fire extinguisher cylinders are specifically designed to contain a specific type of extinguishing agent, such as CO2 or foam. They are engineered to release these agents in a controlled manner to extinguish fires. The pressure and temperature conditions in which these cylinders operate are strictly limited to ensure safe and effective operation.

These cylinders contain liquified CO2 that is pressurized to quench a fire. When a gas is liquified under pressure, the container can hold a larger quantity of the gas. CO2 liquifies at a fairly low pressure and temperature, making it a suitable choice for fire extinguishing applications.

Challenges with Oxygen Refilling

Oxygen, however, behaves differently. At the temperatures and pressures at which CO2 liquifies, oxygen remains a gas. To liquify oxygen, much higher pressures and extremely low temperatures are required, which far exceed the operational limits of standard fire extinguisher cylinders.

Even if we were to somehow manage to achieve the necessary pressures and temperatures, the amount of oxygen that could be stored would be minuscule. Each fire extinguisher cylinder would provide only a few liters of oxygen, which would not suffice for an extended period, especially for a critical situation like a COVID patient in need of breathing assistance.

Health and Safety Concerns

Attempting to refill oxygen using fire extinguisher cylinders is not only ineffective but also dangerous. Medical and industrial sources specifically designed for oxygen storage and dispensing are the safest and most reliable options. Using an inappropriate container for oxygen can lead to several risks, including:

Pressure surges and potential explosions due to incorrect handling of gases under high pressure Contamination of oxygen with other gases from the extinguisher, compromising its purity Incorrect dosing and inhalation of harmful substances Health risks due to inadequate pressurization or improper equipment

Expert Opinion and Scientific Limitations

Scientific and engineering experts have thoroughly investigated the feasibility of using fire extinguisher cylinders for oxygen refilling. Their knowledge of the properties of gases and the limitations of various containers makes their conclusions reliable. If such a solution were effective, experts would have suggested it by now, particularly given the widespread need throughout the ongoing pandemic. The lack of such a recommendation underscores the unfeasibility of the idea.

It is important to recognize the ingenuity of individuals who propose such solutions. However, it is crucial to validate these ideas through proper research and safety checks. Proposing untested and unverified solutions without due diligence can create dangerous situations and may do more harm than good.

Conclusion

In summary, repurposing fire extinguisher cylinders for oxygen refilling is not a practical or safe solution. The design and operational limitations of these cylinders make them unsuitable for storing or dispensing oxygen. Seeking out appropriate medical or industrial sources for oxygen is the safest and most effective approach. By adhering to established safety protocols and guidelines, we can ensure that everyone receives the necessary care and oxygen during critical times.

Tl;dr: No, this idea is not likely to work and could be highly dangerous.
