      There are three types of Civil Defense siren signals: advance warning, air raid warning and de-alarm. Identifying air defense warnings is the basis for correct protective actions. If the three civil Defense alarm signals are confused, the consequences can be unimaginable.
      The pre-alarm sound signal is stipulated as: sound for 36 seconds, stop for 24 seconds, repeat three times as a cycle, and the duration is 3 minutes. Signal.
      After hearing the advance warning, citizens should immediately turn off the power switch, turn off the gas, extinguish the fire, carry personal protective equipment and necessary daily necessities, take care of the elderly and children, and enter the civil air defense project or designated hidden areas quickly and orderly.
     The sound signal of the Air-Raid Sirens is stipulated as: sound for 6 seconds, stop for 6 seconds, repeat 15 times as a cycle, and the duration is 3 minutes. A warning signal to sound in the event of an attack on an urban target.
      After the public hears the air raid siren, all personnel should immediately go to the nearest civil air defense project to hide, except for the staff in various industries (units) who must stick to their posts.
      The audible signal for releasing the alarm is stipulated as follows: a long beep sound continuously for 3 minutes. It is characterized by "no interval". It is a warning signal issued when the danger of enemy air strikes has been lifted.
       Citizens should return to their homes and work in an organized and orderly manner after hearing that the alarm has been lifted. When the enemy's air strikes cause houses to collapse, fires, casualties, etc., under the unified organization of the unit or community where they are located, actively carry out self-rescue, mutual rescue, firefighting, emergency repairs and other actions to eliminate the consequences of air strikes and restore production and living order as soon as possible. Minimize the damage caused by air strikes.
       What we heard on the anniversary of the September 18th Incident was an early warning.
