Household shelters (HS)

The HS in your HDB flat is designed to serve as a civil defence shelter. It is fitted with a steel door, along with strengthened floor, walls and ceiling to protect occupants in the event of a wartime emergency.

Like other structural components of the flat, the following features of the HS must not be tampered with during renovation:

  • Reinforced walls
  • Reinforced floor slab
  • Ceiling
  • Steel door

Fixtures that cannot be removed easily in an emergency should not be placed or installed in the HS as these may hamper your efforts in preparing your HS for occupation in the event of a wartime emergency.

Preparing your HS during a wartime emergency

The HS is only to be occupied during a wartime emergency. During a wartime emergency, the SCDF will inform residents to prepare their HS for occupation. To find out how to prepare your HS for occupation, please refer to SCDF Emergency Handbook (Chapter 4 on Wartime Emergencies - Shelter Protection) for more information. You can download a copy of the SCDF Emergency Handbook via https://www.scdf.gov.sg/home/community-volunteers/publications.
