1. Identification/Recognition.
Initial response: Identify, Immobilise and Disable
The following procedures should be used whenever you are dealing with a KONA EV at an emergency scene. However, all
operations should be consistent with your department’s standard operating procedures, guidelines, and any applicable
laws. When an EV is damaged in a collision, the high-voltage safety systems could have been compromised and present a
potential high-voltage electrical shock hazard. Exercise caution and wear appropriate personal protective equipment (PPE)
safety gear, including high-voltage safety gloves and boots. Remove all metallic jewellery, including watches and rings.
Identify
The KONA EV is built on a conventional KONA chassis and therefore the appearance looks very similar to the internal
combustion engine model.
The KONA EV is an electric vehicle. Emergency responders should respond to emergency scenarios involving the KONA
accordingly, exercising extreme care and caution to avoid contact with the high-voltage system within the vehicle.

6. In case of fire.
6.1 Firefighting operations
Strict precautions must be taken while conducting firefighting operations due to following reasons:
• Lithium-ion batteries contain electrolytes that can vent, ignite, and produce sparks when subjected to temperatures
above 300°F/149°C.
• Vehicle may burn rapidly with a flare-burning effect.
• Even after the high-voltage battery fire appears to have been extinguished, renewed or delayed fire can occur.
• Use a thermal imaging camera to ensure the high-voltage battery is completely cooled before leaving the incident.
• Always advise second responders that there is a risk of the battery re-igniting.
• In a fire, submersion or a collision that has compromised the high-voltage battery, always store it in an open area
with no exposures within 50 feet/15 meters.
• A burning battery could release hydrogen fluoride, carbon monoxide, and carbon dioxide gasses. Use NIOSH/MSHA
approved full-face self-contained breathing apparatus (SCBA) with full protective gear. Even if the high-voltage battery
pack is not directly involved in a vehicle fire, approach the vehicle very carefully.
6.2 Extinguishers
• Small fires that do not involve the high-voltage battery should be extinguished using an ABC fire extinguisher (ex. fire
caused by wiring harnesses, electrical components etc.)
• Do not attempt to extinguish fires that involve the high-voltage battery with small amounts of water as this can result
in electrocution. Fires that involve the high-voltage battery should be extinguished using large amounts of water (max
10,000 litres) to cool the high-voltage battery. Firefighters should not hesitate to pour larger amounts of water on the
vehicle in such scenarios. Make sure the battery is fully cooled to avoid fire re-ignition.

6. In case of fire.
6.3 How to deal with the situation
6.3.1 Vehicle fire
• Use a large volume of water (max. 10,000 litres). The water must cool down the battery.
• If water is put into the high-voltage battery casing, it will be better to cool down the battery (but never attempt to
penetrate the high-voltage battery or its casing to apply water).
• Soaking the vehicle in the container filled with water can be an effective way to extinguish the fire.
*If electrolyte solution leakage, or any damage to the HV battery casing is observed.

Extinguish the fire with a large amount of water.
Don’t use seawater or salt water, as it can generate
a toxic vapor or cause the re-ignition.

6.3.2 High-voltage battery damage and fluid leaks
If electrolyte solution leakage, or any damage to the lithium-ion battery casing is observed, the first responders should
attempt to neutralise the battery by applying a large volume of water to the battery pack while wearing appropriate Personal
Protective Equipment (PPE). The neutralisation process helps stabilise the thermal condition of the battery pack but does not
discharge the battery.
• Do not put any smoke, spark, flame around the vehicle.
• Do not touch or step on the spilled electrolyte.
• If an electrolyte leak occurs, wear appropriate solvent resistant PPE and use soil, sand, or a dry cloth to clean up the
spilled electrolyte. Be sure to adequately ventilate the area.
The high-voltage battery contains electrolyte solution. To avoid exposure to electrolyte solution and serious personal
injury, always wear appropriate solvent resistant PPE (Personal Protective Equipment) and SCBA (Self-Contained Breathing
Apparatus).
• Electrolyte solution is an eye irritant. In the event of contact with eyes, rinse with plenty of water for 15 minutes.
• Electrolyte solution is a skin irritant. Therefore, in the event of contact with skin, wash off with a soap.
• Electrolyte liquid or fumes coming into contact with water will create vapours in the air from oxidization. These
vapours may irritate skin and eyes. In the event of contact with vapours, rinse with plenty of water and consult a doctor
immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Inhale fresh air and wash mouth
with water. Consult a doctor immediately.

6.4 High-voltage battery re-ignition by stranded energy
Damaged cells in the high-voltage battery can experience thermal runaway* and re-ignition. To prevent re-ignition, the first
responder and second responder need to be aware of the risk of stranded energy* which remains in the damaged cells and
lead to re-ignition.
*Thermal runaway: The originating cause of thermal runaway is generally short-circuiting inside a battery cell and a resulting
increase in the cell’s internal temperature. Battery produces heat with thermal runaway, and it can spread from one battery
cell to many cells, in a domino effect.
*Stranded energy: Energy remains inside any undamaged battery cells after the accident. That stranded energy can cause a
high-voltage battery to reignite multiple times after firefighters handle a fire.
How to prevent re-ignition (Mitigating stranded energy risk)
Use a thermal imaging camera to ensure the high-voltage battery is completely cooled before leaving the incident. Always
advise second responders that there is a risk of the battery re-igniting.
1. 12V battery terminal disconnection (to depower battery management system)
2. High-voltage shut off (refer to pages 7-9)
3. Discharging the high-voltage battery (refer to pages 22-23)

7. In case of submersion.
7.1 Submerged or partially submerged vehicles
Some emergency responses can involve a submerged vehicle. A KONA EV that is submerged does not have high-voltage
components on the vehicle’s body or framework. It is safe to touch the vehicle’s body or framework if there is no severe
damage to the vehicle, whether it is in water or on land.
In the event the vehicle is submerged or partially submerged, remove the vehicle from the water before attempting to disable
the vehicle. Drain the water from the vehicle. Use one of the methods described in pages 7-11 to disable the vehicle. Then,
discharge the battery by referring to pages 22-23.
• If severe damage causes high-voltage components to become exposed, responders should take appropriate precautions
and wear appropriate insulated personal protective equipment.
• Do not attempt to remove a safety plug while the vehicle is in water.
Failure to follow these instructions can lead to death or serious injury by electrocution.
