Fire extinguishing agents are indeed considered a general hazard often found in aviation. While these agents are essential for aircraft safety and emergency situations, they can also pose risks if not handled properly. For example, certain fire extinguishing substances can be toxic or corrosive, and improper use or accidental release can lead to hazardous conditions for personnel working around aircraft.

In aviation settings, it's crucial to be aware of the proper handling, storage, and application of fire extinguishing agents to mitigate risks associated with their use. Understanding the potential hazards associated with these agents ensures that personnel can maintain safety protocols and respond appropriately in case of fire emergencies. This contextualizes the importance of recognizing fire extinguishing agents not just as safety tools but as potential hazards when mishandled.
