The Exit Sign—A Lifesaving Sign System

Exit signs are a common sight in our built environment. However, this simple sign system becomes extremely vital during emergencies, indicating the escape routes to evacuees and, thus, saving lives.


During an evacuation, visibility may be low and the situation chaotic, so being able to locate an exit could mean the difference between life and death. Therefore, these signs should be regularly tested and maintained to ensure that they are always functioning optimally in case of emergency.

The following regulations thus require premises to have an operationally-ready and well-maintained Exit Sign System:

  • Code of Practice for Fire Precautions in Buildings 2018 (Fire Code 2018) by the SCDF

  • SS 563: 2010 (2017) Part 1 and 2 (formerly SS CP 19)

  1. SS 563-1: 2010 (2017) Code of Practice for the design, installation and maintenance of Emergency Lighting and Power Supply Systems in buildings - Part 1: Emergency Lighting

  2. SS 563-2: 2010 (2017) Code of Practice for the design, installation and maintenance of Emergency Lighting and Power Supply Systems in buildings - Part 2: Installation requirements and maintenance procedures


Who is responsible for the Exit Sign System?

  • Building Owners and Council Members are responsible by regulation

  • Fire Protection Specialists, like BSE, MCST Managing agencies, and/ or technicians are engaged to assist Building Owners and Council Members


What kind of maintenance will the Exit Sign System need and how often?

According to regulations, the recommended frequency of inspection for the Exit Sign System in buildings is MONTHLY. However, the regulatory testing and maintenance of the Exit Sign System are conducted ANNUALLY.
