Total Defence Day: Sounding of Public Warning System (PWS)

 

The SCDF will sound the Public Warning System (PWS) on 15 February 2011 at 12:05pm to commemorate Total Defence Day.

The Singapore Civil Defence Force (SCDF) will be sounding the 'Important Message' signal through the islandwide network of Public Warning System (PWS) sirens, in support of Total Defence Day.

The public should not to be alarmed by the minute-long sounding exercise.

When the signal is sounded, the public can immediately tune in to any local radio station to listen to a special info-mercial broadcast on the PWS signals.

The sounding is part of SCDF's continuous efforts to familiarise the public with the three PWS signals and raise awareness on how they should react upon hearing each signal.

Besides the 'Important Message' signal (characterised by pulsating blasts), the two other signals are the 'Alarm' and the 'All Clear' signals, which are characterised by wailing and continuous blasts respectively.
