Which of the following is included in the PDIs of Halon?

The inclusion of stowage, quantity, and pressure gauge status in the pre-departure inspection (PDI) of Halon extinguishers is essential for ensuring the proper functioning and readiness of this fire suppression system.

The quantity signifies how much Halon is available in the extinguisher, as it directly relates to the effectiveness of the device in extinguishing a fire.

If the pressure is too low, the extinguisher may not function properly during a critical time.

Regarding the other options, while they might seem relevant, they do not encompass the specific requirements for a PDI of Halon extinguishers. Checking the color code is important for identifying the type of extinguisher but does not provide as comprehensive an assessment as the stowage, quantity, and pressure gauge status. Condition and brand name, while useful for identification, are not operational factors directly tied to the extinguisher's readiness. Fluid levels are applicable to other
