Catching Fire - Pytes HV48100 User Manual

When handling chemical leakage incidents, professional maintenance personnel and firefight-
ers must wear necessary protective equipment such as air-purifying respirator and other PPE.
For household members, if battery leakage occurs, you are advised to follow the following
steps:
(1) Stop the ESS immediately and set the battery power control module (DCDC) switch to
OFF.
Turn off the AC circuit breaker of the inverter and set the inverter DC switch to OFF.
(2) Indoor installation scenario: Indoor personnel should quickly evacuate, open the doors,
windows, and ventilation devices of the room, and turn off indoor fire sources during the
evacuation. Outdoor installation scenario: Notify outdoor personnel to stay away from the site
and set up a warning sign to isolate the area.
(3) After evacuating to a safe area, notify professional maintenance personnel or firefighters to
handle the emergency.
Avoid contact with electrolytes or released gases. In the case of contact, take the following
measures:
Inhalation: Evacuate from contaminated areas, get fresh air immediately, and seek immedi-
ate medical attention.
Eye contact: Immediately wash your eyes with water for at least 15 minutes, do not rub
your eyes and seek immediate medical attention.
Skin contact: Wash the affected areas immediately with soap and water and seek immedi-
ate medical attention.
Intake: Seek immediate medical attention.

8.2 Catching Fire

DANGER
In case of smoke or fire, if there is a large amount of smoke in the battery storage room, do not
open the door to prevent explosion risks and toxic gas inhalation.
If a lithium battery catches fire, flammable and toxic gases will be released. Therefore, during
the extinguishing process, all firefighters must wear a full set of protective suites, including
flame retardant/fireproof clothing, air-purifying respirator or breathing apparatus, firefighter
helmet and mask, and insulated shoes.
A lithium battery fire may last for several hours. After it is extinguished, the fire may be reignit-
ed by the heat generated from residual ingredients due to internal cell damage. After an open
flame is extinguished, continue spraying water to cool the batteries. Wait until the battery
temperature drops to the room temperature±10°C and monitor for 24 hours to ensure that
there is no sign of temperature rise before removing the batteries. Move the removed batteries
to a safe place (an open and safe outdoor place is recommended).
Procedure
1. If batteries emit smoke or catch fires, notify all household members to evacuate immediately.
2. After evacuating to a safe outdoor area (20 m away is recommended), call the fire depart-
ment immediately. While waiting for the fire rescue, contact the installer and Pytes technical
support.
