What is the Mark?

is not a mark that satisfies the

requirements for “Listing” nor is it accepted

by AHJs in most of the United States

only means the product was “self

certified” to specific European

Directives for ease of movement into

and within European Union

“Ignis Servus Non Dominus”

Fire should be our servant

The Station

The Station nightclub fire

on February 20, 2003 was

the fourth deadliest nightclub

fire in U.S. history, killing 100

people and injuring nearly

200.

Most perished on the night of

the fire, and 4 died later from

their injuries at local

hospitals.

The Problem!

“We are proud to offer 4.5 ft.. X 8 ft.. X 1 1/8 inches thick (36 sqft) sheets of soundproof egg crate foam. Our sound proof foam is

convoluted on one side producing greater sound absorbing capabilities. The acoustical studio foam is a 1.5 lb. density Ester. Our egg crate studio foam is UL94 HF-1 rated which makes the foam

virtually self-extinguishing when it comes in contact with a flame. This allows greater comfort knowing your foam is non-flammable. The

egg crate acoustical foam has an NRC (Noise Reduction Coefficient) rating of .9 out of a possible 1. The egg crate foam virtually

eliminates outside noise and absorbs all sound waves.”From Acoustical Foam Panel

WHAT IS IT & WHY IS IT IMPORTANT?

What is it?

Fire-resistive Door Assembly:

Is capable of providing a

specified degree of fire

protection when closed and

includes:

I. Door Blank,

II. Door Frame

III. Door hardware

Why is it important?

Door Assembly is designed to:

• Close off openings in walls

• Slow the spread of fire from

one side of the opening to

the other protected side

Normally is means to:

• Burn through (wood doors) or

• Mechanical failure due to

deflection or expansion (steel

doors).

INTRODUCTION

Li-ion Battery Designs and Challenges

High Voltage/High Capacity

Thermal Gradient and Safety are major Challenges

Low Voltage/ Low Capacity

Battery Installation Scenarios

FIRE SAFETY APPROACH

NEC: National Electric Code (NFPA 70)

NFPA 855: Standard for the Installation of Stationary Energy Storage Systems

ICC: The International Fire Code, International Residential Code

UL 1642: Lithium Batteries

Testing for Performance

UL 9540A TEST STANDARD

Scope

Evaluate fire characteristics of a battery energy storage system that undergoes thermal runaway. Data generated will be used to determine the fire and explosion protection required for an installation of a battery energy storage system.

Match Fire Protection of Installation

to Performance of BESS

• Whether cell can exhibit thermal runaway

• Thermal runaway characteristics

• Gas composition (flammability)

• Propensity for propagation of thermal runaway

• Heat and gas release rates (severity/duration)

• Flaming/deflagration hazards

• Evaluation of fire spread


• Deflagration hazards

• Re-ignition hazards

• Effectiveness of fire protection system(s)


• Deflagration hazards

• Re-ignition hazards
