What critical information is marked on the label post-testing?

The label post-testing must include the inspection due date as a critical piece of information. This date indicates when the next inspection or servicing is required, ensuring that the extinguisher remains functional and compliant with safety regulations. Regular inspections are essential to guarantee that the extinguisher is in proper working condition and ready for use in case of a fire emergency. This information is vital for both the personnel responsible for fire safety and any regulatory bodies that may require verification of compliance.

Without this date, there would be uncertainty regarding when the extinguisher should be checked again, which could lead to potential safety hazards if the device is not maintained appropriately. Other information, like the type of extinguisher or test results, while useful, does not hold the same level of urgency for ongoing safety compliance as the inspection due date.
