sprinkler systems, smoke detection, ammable gas detection, and
explosion-proof can be exempt. However, the requirements on
mechanical exhaust ventilation, pressure relief clearance above the ESS,
heat dissipation, and maintenance clearance shall be met.
– When approved by the re department, the re control and suppression
systems, size and separation requirements, and the water supply shall be
permitted to be omitted in ESS dedicated-use buildings located more
than 100 ft (30.5 m) from buildings, lot lines that can be built upon,
public ways, stored combustible materials, hazardous materials, high-

infrastructure.
● Requirements for oshore indoor applications:
– If the ESS is less than 500 m away from the coast, ensure that it is
located in an indoor environment within a dedicated protective building
that has controllable temperature and humidity using air conditioners.
The indoor environment must meet the C4 or higher level specied in ISO
12944/ISO 9223. In addition, the preceding site selection requirements for
indoor applications must be met.
– Anti-salt fog measures must be taken for outdoor air conditioners and
mechanical ventilation devices. Anti-salt fog lters must be installed at
the air intake and exhaust vents, or anti-salt fog air conditioners or
ventilation devices must be used. The lters must be maintained and
replaced periodically.
5.2 Clearance Requirements
The following gure shows the minimum clearance requirements for installation
and O&M. The equipment clearances must also meet the site selection
requirements (see 5.1 Site Selection Requirements).
