I.                    Burn Bags 
The use of burn bags has been a common practice for many years in the aviation industry to contain and isolate lithium batteries and other dangerous goods that are suspected of thermal runaway or fire hazards. However, recent research and incidents have shown that relying solely on burn bags is not a good idea when it comes to managing lithium battery thermal runaways in aircraft. This tutorial will delve into the reasons why burn bags are not an effective solution and what alternatives can be considered to ensure the safety of passengers and crew.

 

II.                 Understanding Lithium Battery Thermal Runaways
Before we discuss the limitations of burn bags, it is crucial to comprehend the concept of lithium battery thermal runaways. Lithium batteries, commonly used in electronic devices and transportation applications, can generate excessive heat, leading to an uncontrolled chain reaction. This process can result in a fire, explosion, or the release of toxic gases. Therefore, preventing and managing thermal runaways is of utmost importance in aviation safety.

 

III.               Limitations of Burn Bags

 

1. Insufficient Containment: Burn bags are primarily designed to contain known hazardous materials temporarily. However, when it comes to lithium battery thermal runaways, this containment method falls short. Thermal runaway events can cause a rapid increase in temperature and pressure, which can easily surpass the limitations of a burn bag, leading to its failure.

 

1. Limited Fire Suppression: While burn bags may provide some level of fire suppression, they are not specifically designed for this purpose. The materials used in burn bags are not effective in suppressing or extinguishing lithium battery fires. Therefore, relying solely on burn bags can lead to an inadequate response to fire incidents involving thermal runaways.

 

 

1. Risk of Smoke and Toxic Gas Emissions: Burn bags are typically made of materials that may not effectively contain smoke, toxic gases, and other byproducts generated during a thermal runaway. This can present serious health hazards to passengers and crew, compromising their safety in the event of an incident.

 

IV.               Alternative Safety Measures

 

Considering the limitations of burn bags, it is crucial to explore alternative safety measures to manage lithium battery thermal runaways effectively.

Some viable options include:

 

1. Fire Suppression Systems: Implementing advanced fire suppression systems specifically designed to handle lithium battery fires can significantly improve the response to thermal runaways. These systems utilize fire suppression agents that are effective in extinguishing this type of fire and can better contain the hazardous byproducts.

 

2. Containment Solutions: Investing Enhanced in containment solutions specifically designed for thermal runaways can mitigate the risks associated with lithium battery incidents. These solutions can include specialized containers or compartments equipped with thermal management systems and fire suppression mechanisms.

 

3. Improved Handling Procedures: Educating and training aviation personnel on the proper handling and transport of lithium batteries is crucial to prevent thermal runaways. Implementing strict protocols for inspection, packaging, and documentation can significantly reduce the likelihood of incidents occurring onboard an aircraft.

 

While burn bags have been traditionally used to contain suspected dangerous goods, they are not an appropriate solution for lithium battery thermal runaways in aircraft. With the potential risks of fire, explosion, and toxic gas emissions, it is essential to explore alternative safety measures such as enhanced fire suppression systems, specialized containment solutions, and improved handling procedures. By prioritizing these measures, the aviation industry can better ensure the safety of passengers and crew in the face of this critical safety concern.

 

The governing entities encourage education in the form of e-learning hosted by the simulator training centers currently. This education is available in remote, In person or through various libraries including CAE.
