Chapter 10

Requirements for Special Installations

Chapter 10 governs the fire safety requirements for four categories of special installations: LPG cylinder systems, solar photovoltaic (PV) systems, energy storage systems (ESS), and electric vehicle (EV) charging stations. It prescribes separation distances, maximum quantities, ventilation standards, and emergency disconnection requirements. Designers and Qualified Persons must ensure each installation type meets the specific siting, protection, and safety provisions before obtaining regulatory approval.

Scope: Applies to commercial, industrial and residential premises installing LPG cylinders for cooking or industrial hot works; buildings with roof-mounted, wall-mounted or wall-integrated PV systems; any premises installing battery-based energy storage systems above threshold stored energy; and buildings with EV charging stations (except PG I buildings for EV requirements).
