What must be recorded after hydrostatic testing of a fire extinguisher?

After hydrostatic testing of a fire extinguisher, it is essential to record the test date and results. This documentation serves multiple important purposes. First, it establishes a clear record of when the testing was conducted, which is crucial for determining the next inspection date, as most extinguishers require regular testing at specific intervals. Secondly, documenting the results provides a valuable snapshot of the extinguisher's condition post-testing, including whether it passed or failed. This information is vital for safety compliance and ensures that the equipment is reliable when needed in an emergency situation. Keeping accurate records of test dates and results is a standard best practice within the fire safety industry to maintain safety standards and guarantee the operability of fire extinguishers.
