What is required to be indicated by a hole punch on the CO2 hose assembly conductivity test label?

A hole punch on the CO2 hose assembly conductivity test label is used to indicate the month and year the test was performed. This is an important practice in ensuring that fire safety equipment is regularly maintained and inspected for safety compliance and functionality. By marking the date of the test, technicians can keep track of inspection intervals and ensure that any potential issues are addressed promptly. This helps in maintaining a high standard of safety and preparedness in the event of a fire emergency, as the integrity of the hose assembly must be regularly verified to ensure proper operation of the fire extinguisher. It's essential for thorough record-keeping and provides clear documentation of compliance with safety regulations for portable fire extinguishers.
