1.3 Response to emergency situations
The RESU battery pack comprises multiple batteries that are designed to prevent haz-
ards resulting from failures. However, LG Chem cannot guarantee their absolute
safety.
Leaking batteries
If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas. Elec-
trolyte is corrosive and contact may cause skin irritation and chemical burns. If one is
exposed to the leaked substance, do these actions:
Inhalation: Evacuate the contaminated area, and seek medical attention immediately.
8

Saftey
Eye contact: Rinse eyes with owing water for 15 minutes, and seek medical attention
immediately.
Skin contact: Wash the aected area thoroughly with soap and water, and seek med-
ical attention immediately.
Ingestion: Induce vomiting, and seek medical attention immediately.
Fire
In case of a re, make sure that an ABC or carbon dioxide extinguisher is
nearby.
WARNING
The battery pack may catch re when heated above 150°C.
If a re breaks out where the battery pack is installed, do these actions:
1. Extinguish the re before the battery pack catches re.
2. If it is impossible to extinguish the re but you have time, move the battery pack
to a safe area before it catches re.
3. If the battery pack has caught re, do not try to extinguish the re. Evacuate peo-
ple immediately.
WARNING
If the battery catches re, it will produce noxious and poisonous gases. Do not
approach.
Wet batteries
If the battery pack is wet or submerged in water, do not try to access it. Contact LG
Chem or your distributor for technical assistance.
Damaged batteries
Damaged batteries are dangerous and must be handled with extreme caution. They
are not t for use and may pose a danger to people or property. If the battery pack
seems to be damaged, pack it in its original container, and then return it to LG Chem
or your distributor.

CAUTION
Damaged batteries may leak electrolyte or produce ammable gas. If you suspect
such damage, immediately contact LG Chem for advice and information.
