Site and Environmental Protections (IEC 62485-2 Section 9.2, 9.4)
Battery rooms must be protected from extreme environmental in昀氀uences such as temperature, humidity, and
airborne contamination. The 昀氀oors shall be designed to support the weight of the battery plus a design margin.
Battery Enclosures should protect against external hazards, hazards generated by the battery, unauthorized
personnel, and external environmental in昀氀uences. They should have adequate ventilation to prevent the
accumulation of hydrogen gas even under fault conditions.
For vented batteries, the 昀氀oor of the battery room should be sealed and resistant to electrolyte. Methods may
include trays or liner-based spill containment systems. The entire contents of one cell or multi-cell container
must be contained in the spill containment system. Also reference IEEE 1578 - IEEE Recommended Practice
for Stationary Battery Electrolyte Spill Containment and Management.
Measures should be taken to prevent the accumulation of electrostatic charges, which can ignite 昀氀ammable
gases. This includes using the appropriate cleaning cloths such as cotton to avoid creating static electricity.
Voltage of a static charge can vary depending on factors such as the materials involved, the humidity level,
and the amount of friction that has occurred, but can be a few thousand volts to tens of thousands of volts.
This may ignite hydrogen present near the 昀氀ame arrester or battery vent.
Warning Labels and Notices (IEC 62485-2 Section 9.3, 11)
Signs are also required per ISO 3864 and displayed on the outside of the battery room (昀椀gure 2).
Battery Room Sign
A clear sign should be posted at the entrance to the battery room
indicating the presence of batteries.
Dangerous
Voltage Sign
If the battery voltage exceeds 60 volts, a sign should warn of the
dangerous voltage.
Fire and Smoking
Prohibition
Signs should prohibit 昀椀re, naked 昀氀ames, and smoking in the battery room.
Battery Room
Identi昀椀cation
A sign should clearly identify the room as a "Battery Room" to indicate
the presence of corrosive electrolyte, explosive gases, and dangerous
voltages and currents.
Battery Room
Contact Information
Though not required by the standard, it is a good practice to state the
names and contact phone number for those who are responsible for the
battery room. This allows emergency personnel with access to a person
who may provide quick information about the hazards of the room.
By adhering to these requirements, operators can signi昀椀cantly
reduce the risks associated with stationary secondary battery
installations and ensure a safe working environment. It also
provides 昀椀rst responders with information as they respond to
昀椀res or spill incidents.
