SCDF public warning system to sound islandwide on Sept 15

The Singapore Civil Defence Force (SCDF) will sound the public warning system (PWS) islandwide on Sept 15, at 6.20pm

During the sounding, the "Important Message" signal will be sounded through the PWS sirens and smartphones with the SGSecure mobile app installed.

Members of the public connected to the Singtel network will also receive an SG Alert on their mobile phones.

SCDF said that SG Alert complements the PWS by quickly alerting the public and providing information on actions to take during an emergency.

During an ammonia leak incident at a ice and cold storage facility in Jurong on June 29, an SG Alert was sent out to people in the area.

They were advised to stay clear of the area.

SCDF sounds the PWS sirens annually at 6.20pm on Feb 15 and Sept 15.

The annual sounding and broadcast message are part of the SCDF's continuous efforts to familiarise the public with the PWS signals and to raise awareness on how the public should react upon hearing the signal.

Members of the public should tune in immediately to any local radio stations or free-to-air TV channels upon hearing the "Important Message" signal.

For this year's Exercise SG Ready 2026 , held in support of Total Defence Day, the SCDF made a one-off change to the sounding date — from Feb 15 to Feb 1 — to remind Singaporeans that disruptions can occur at any time.

新加坡民防部队将于9月15日下午6点20分在全岛范围内启动公共警报系统。

鸣笛期间，“重要信息”信号将通过 PWS 警报器和安装了 SGSecure 移动应用程序的智能手机发出。

连接到新加坡电信网络的公众成员也将在手机上收到SG Alert警报。

新加坡民防部队表示，SG Alert 可以快速向公众发出警报，并提供在紧急情况下应采取的行动信息，从而对公共安全警报系统起到补充作用。

6月29日，裕廊一家冰块和冷藏设施发生氨气泄漏事故，SG Alert向该地区的人们发出警报。

他们被建议远离该区域。

新加坡民防部队每年 2 月 15 日和 9 月 15 日下午 6 点 20 分鸣响公共安全警报器。

每年鸣放警报和广播信息是新加坡民防部队持续努力的一部分，旨在让公众熟悉公共安全警报信号，并提高公众在听到警报信号后应如何应对的意识。

公众听到“重要信息”信号后，应立即收听当地广播电台或收看免费电视频道。

为响应全民防卫日，新加坡民防部队在今年的“SG Ready 2026”演习中，将鸣钟日期从2月15日改为2月1日，以提醒新加坡人，干扰随时可能发生。
