• Do not enter the room under any circumstance.
• Avoid contact with the leaking liquid or gas.
• Call the Local Emergency number or Fire Brigade if necessary.

If one is exposed to the leaking substance, follow the suggestions below to minimize the chance of injury:

• Inhalation: Evacuate the contaminated area, and seek medical aid.
• Eye contact: Rinse eyes with copious amounts of water for at least 15 minutes, and seek medical aid immediately.
• Skin contact: Wash the affected area thoroughly with plenty of water for at least 15 minutes. If possible, remove or saturate contaminated clothing with water. Seek medical aid if the patient is distressed.
• Ingestion: Induce vomiting, and seek medical aid immediately.

Wipe out the contacted area with a sponge or cloth that is soaked in water until you obtain medical aid. These materials can damage skin and eyes, causing blindness.

Fire
Fire may occur with the battery despite its careful design. Likewise, a fire or unusually high temperatures near the battery can cause it to catch fire.

Protective equipment
A respirator is not required during normal operations.
In the event of a fire, hazardous fumes including carbon monoxide, carbon dioxide, and/or various hydrocarbons may be emitted. To comply with the Personal Protective Equipment Directive (89/686/EEC), use a full-face self-contained breathing apparatus (SCBA) with full protective gear during fire fighting.

Fire fighting

In the event of a fire, only qualified firefighters with appropriate protective equipment are permitted to enter the room where the battery is located. It may take a long time to completely extinguish the fire. Consider allowing the system to burn. Smoke indicates that the battery is still burning. Always note that there is a risk of the battery re-igniting.

Proceed as follows for fire-fighting.

1. Shut off any connected power system or electronics such as the battery, battery isolator, PV DC isolator(s), AC isolator, solar supply main switch and normal supply main switch.
2. Perform an adequate knock down on the fire before entering the incident's hot zone.
3. If the battery catches on fire, use fire-fighting sand, CO₂ extinguisher, or other emergency fire extinguishing equipment approved by fire fighters to extinguish the fire.
4. If the fire is not from the battery and has not spread to it yet, use an ABC fire extinguisher to extinguish the fire. Remove batteries and other ignition sources from the scene of a fire.

Wet Batteries
If the battery is submerged in water, do not let people access it, and then contact Sungrow or an authorized service partner for technical support.
If a battery is submerged in water or flooded, first, switch off all circuit breakers in the system to cut off the power supply to the battery. Wait until floodwaters subside and do not approach near battery. If someone needs to go into the flooded water, wear insulated full length rubber boots and gloves.
Do not use a flooded battery again.

Damaged Batteries
The battery consists of lithium-ion cells. These are considered dry cell batteries. If the battery is damaged, only a small amount of battery fluid can leak.
A damaged battery can cause rapid heating of the battery cells. If you notice smoke coming from the battery area, assume that the battery is burning and take appropriate action as described in "1.3.2 Fire".
Damaged batteries are dangerous and must be handled with extreme caution. They are not fit for use and may pose a danger to people or property. If a battery seems to be damaged:

1. Pack it in its original container.
2. Store it in a separated room like the installation place.
3. Contact SUNGROW.
