4. Do not utilize piercing nozzles or long penetrating irons to fight the fire, as these may damage the lithium-
ion batteries and release flammable gas.

1. Contact the local fire department.
2. Contact the system owner and service organization.
3. Evacuate the immediate area of all nonessential personnel.
4. Secure utility power to the cabinet by opening the main AC disconnect.
5. Using a portable gas meter, periodically sample the air surrounding the cabinet for the presence of
flammable gases.
6. Extinguish the fire using cold water and dry powder.
a. The application of fire fighting dry powders or carbon dioxide extinguishers may eliminate visible
flames on the batteries, but do not provide sufficient cooling to interrupt thermal runaway.
7. If a battery cell or module has experienced thermal runaway and rupture, cool the battery as needed
by spraying it with water.
8. The system is safe to turn over to the owner for repair or disposal once the temperature of the deranged
battery does not increase above ambient when cooling is paused.

The Eaton xStorage 400 stores energy in thirty-six lithium-ion battery modules. Testing has shown that a
thermal runaway in a single cell within a battery module will not release flammable gas into the cabinet or
spread to neighboring cells and modules. These test results provide assurance that the batteries do not
present a hazard to the public.
NOTE Detailed results are available in the UL 9540A test report for project number
4789910728, prepared by UL LLC and issued May 6, 2021.
The xStorage 400 is further protected by a hydrogen detector that continually monitors the hydrogen content of
the air within the cabinet. If 25% of the LFL of hydrogen is detected (approximately 1% by volume), the
xStorage 400 will isolate itself from utility power and shutdown. Upon power loss the ventilation louvers,
installed on a cabinet door, are opened.
Alarms are sent to the system owner and service organization electronically. No visual indications are provided
on the exterior or interior of the cabinet.
Per testing, the gas produced by a failed battery cell is 13.63% CO, 26.65% CO
2
, 39.82% H
2
, and 19.92%
hydrocarbons with a LFL of 5.78% and a burning velocity of 52.3 cm/sec.
This procedure is intended to be executed as a joint operation between the system owner, service
organization, and emergency response personnel.

An alarm in the remote customer interface has been triggered indicating an abnormally high level of hydrogen
within the cabinet and the xStorage 400 has shutdown.
