Which procedure should be followed after extinguishing a fire?

After extinguishing a fire, conducting a thorough investigation and documenting the incident is crucial for several reasons. It allows responders to understand the fire's cause, the effectiveness of the response, and any potential safety issues that arose during the event. This documentation serves as a historical record and can provide valuable information for future training, improving safety protocols, and preventing similar incidents.

Additionally, having a detailed account of actions taken and the outcome can assist in evaluating the performance of firefighting techniques and equipment used. It can also help identify any needed changes in procedures or additional training for personnel. This process is essential not just for accountability, but also for ensuring continuous improvement within fire response operations, which is a key aspect of safety management in any environment, especially in aviation settings where the stakes are high.
