Haz Mat 19/Lithium Ion Energy Storage System

Question 1

Lithium Ion Energy Storage System..

Answer 1

-store energy to supply electrical energy at a future time

ESTOP-shut down entire system

Question 2

DON’T EVER SHUT DOWN SYSTEM without consultation..

Answer 2

UPS (uninterruptible power supply)–battery back up providing power for financial centers, shut not be shut down without consultation of building engineer

Question 3

Stored/Stranded energy..

Answer 3

even after batteries are severely burned, they may still retain high voltage electrical charge (stranded energy)

Question 4

No spill hazard with these type of batteries..

Answer 4

flammable electrolyte –potentialy explosive atmosphere

Question 5

Re-ignition

Answer 5

even after final extinguishment , Li-ion-ESS may re-ginite hours to days

-may not be seen by Thermal imaging camera

Question 6

Procedures are for OUTDOOR/ROOFTOP installation …

NO FIRE/NO SMOKE SHOWING

Answer 6

• determine if ESS battery type is Li-ion
• establish initial danger zone
• all FDNY personnel behind physical barriers (fence)
• minimum 50 feet radius from containers/cabinets
• minimum 100 feet radius from exhaust fan opening (usually located on side opposite FDC) cabinets may not have exhaust system
• ENGINE COMPANIES secure water source, STRETCH precautionary handling , and STRETCH supply lines to supply FDC, if available (does not say charge FDC)
• TRANSMIT 10-80 CODE 1

Question 7

CONFIRMED FIRE/SMOKE SHOWING on arrival…

Answer 7

-determine if ESS battery is LI-ION-ESS (usually signange at FDC, if available )
-initial danger zone
-50 feet radius from container/cabinet
-100 ft radius from Exhaust opening (opposite FDC)
-SHUT DOWN ESS (ESTOP) at FDC or inside electrical room if ESS IS SUPPLYING a building
-ENGINE connect to FDC and CHARGE (signage for pressures and flow rates at the FDC)
-EXHAUSt OVERRIDE SWITCH (exhaust system)
-use exterior lines to cool adjacent cabinets and exposures if present and necessary /use narrow fog or straight stream application and maximum reach of streams
TRANSMIT 10-80 CODE 1

NOTE; IF FDC is located CLOSER than 50 feet from the nearest container , than only enter this area under the order of the IC

Question 8

POST FIRE …

Answer 8

• may open container/cabinet doors after consultation with SME and the fire is extinguished
• FDNY PERSONNEL NEVER ENTER CONTAINER
• NO OVERHAULING ON ANY ESS
• IC shall transfer responsibility to subject matter expert for decommissioning /fire watch.
