Damage to lithium-ion batteries can lead to an atmosphere inside the battery test chamber that is harmful
to health.
DANGER
Risk of occurrence of toxic gases due to damaged or burning cells/modules/sys-
tems. Risk of self-ignition of cells, modules, or battery systems with flue gas (CO)
development. Risk of emission of hazardous gases from the interior of the cham-
ber.
Death by suffocation. Poisoning.
Shut the entire test down when the first signs of a EUCAR hazard level 4 to 6 event
are detected.
Ensure ventilation measures: Active extraction (technical ventilation in accordance
with national regulations) must be connected to the exhaust port on the chamber. Ex-
traction must remain effective throughout operation of the chamber.
Observe the relevant regulations for handling lithium-ion batteries.
During and shortly after operation, the temperature of the inner surfaces almost equals the set-point. The
window, the access ports and the inner chamber will become hot during operation.
CAUTION
Danger of burning by touching hot chamber parts during operation.
Burns.
∅ Do NOT touch the inner surfaces, the front panel around the inner chamber, the win-
dow, the access port area or the charging material during operation.
1.7.3 Notes on handling CO
2
The CO
2
purge when the CO
2
fire suppression device is activated can create a harmful atmosphere inside
the chamber.
Carbon dioxide (CO
2
) in high concentrations is hazardous to health. It is colorless and almost odorless and
therefore practically imperceptible. An active extraction system (technical ventilation according to country-
specific regulations) must be connected to the exhaust air nozzle of the appliance. The extraction must be
effective during the entire operation of the chamber.
Vent out any CO
2
gas that may escape via good room ventilation or a suitable connection to an exhaust
system. We recommend installing a CO
2
warning system.
DANGER
Danger of suffocation and poisoning by high concentration of CO
2
(> 4 Vol.-%).
Death by suffocation.
∅ Do NOT set up the chamber in non-ventilated recesses.
Ensure technical ventilation measures: An active extraction system (technical ventila-
tion in accordance with country-specific regulations) must be connected to the exhaust
air connection of the chamber. The extraction must be effective during the entire oper-
ation of the chamber.
Observe the relevant regulations for handling CO
2
