Hello, your question is whether the civil air defense equipment and machinery of the unit have not been inspected before. Do you need to sign when you take over now? I have not handled the acceptance of the civil air defense equipment and machinery of the unit before. Now when I take over, I need to sign. The acceptance of general civil air defense equipment needs to be carried out by relevant departments or professional institutions, and there will generally be an acceptance report. As the takeover unit, signing the acceptance document may confirm that you have taken over the equipment and are responsible for the subsequent management and use.
