Common Nuisance Sources
Marty Ahrens March 2014 Report, titled Smoke Alarms in U.S. Home Fires
• Steam Nuisance alarms account for no more than 2% of nuisance alarms (down from 5% in 2004)
• Cooking Nuisance alarms account for 73% of nuisance alarms (up from 69% in 2004)

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
UL’s Latin motto:
“Ignis Servus Non Dominus”
Fire should be our servant
and never our Master!

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

From the UL 94 Standard –
Tests for Flammability of Plastic Materials for Parts in
Devices and Appliances
UL 94 test is not applicable for building materials:
“These requirements do not cover plastics
when used as materials for building construction
or finishing.”

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).

Energy Storage Systems
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
• Heat and gas release rates (severity/duration)
• Deflagration hazards
• Re-ignition hazards
• Effectiveness of fire protection system(s)
• Heat and gas release rates (severity/duration)
• Deflagration hazards
