In these situations, the best resource for servicing and maintenance information may be directly from the extinguisher manufacturer. However, for extinguishers installed in aircraft that are used in commercial operations, the maintenance requirements for portable extinguishers are often detailed in the carrier's individual operating specifications. In some situations, the extinguisher manufacturer may provide basic servicing and maintenance information on the identification label. This information should be reviewed during any inspection. Items that are typically checked include: Weighing the container to determine the quantity of extinguishing agent, and checking a pressure gauge to determine the propellant charge. The information on the label may also indicate any time or life limits on the serviceability of the extinguisher or the requirements for hydrostatic testing, If required Nitrogen-pressurized extinguishers have pressure gauges on them with red and green arcs on their dial. As long as the gauge is indicating in the green arc, the gas pressure is sufficient. Any servicing or maintenance performed on the extinguisher must be recorded in the aircraft's permanent maintenance records and is often also indicated directly on the extinguisher container As shown in figure 25. Additional items to check include releasing the extinguisher from its mounting bracket to determine its ease of removal and checking that the activation-trigger safety pin is properly installed. If there is any doubt as to the integrity of the extinguisher's condition, it should be replaced or sent to a certified repair station that is authorized to perform full servicing and maintenance on portable fire extinguishers.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
