All of the following were objectives of the NIST Technical Study EXCEPT:

to identify the cause of the fire

evaluate fire spread

study conditions within the structure

identify potential revisions to building and fire codes

Once the fire extended into the holding area the simulation indicates extension into the main showroom due to what factor?

Open roll-up doors

Failure of lightweight metal walls

Lack of an installed ceiling in the area

Removal of the window in front of the showroom

What impact did the removal of the windows in the main showroom have on the fire?

Reduced overall temperature in the space

Drew the fire to the front of the building

Reduced the production of some in the building

Pushed the fire into the High Bay Warehouse

In the development of an incident timeline, the dispatch and arrival times are called:

soft times

estimated times

system times

benchmark events

Computational models such as the one used in this program should not be utilized:

to test a hypothesis

as the sole basis of a fire origin and cause determination

estimate the tenability of a space during the fire

predict the impact of suppression systems on fire growth and development

In the development of the incident timeline what information was linked with fire department radio transmission information to track smoke and fire conditions?

Media reports

The written incident log

Fire fighter interviews

Dash cam footage from police units

What was the mechanism of heat transfer from the Loading Dock into the warehouse identified in the simulation?

Fire gasses flowing through an unprotected opening

Failure of a roll-down door

Heating of a metal wall causing items in the warehouse to ignite

Lack of rated ceiling system allowing fire travel into the interstitial space

The fuel load in the main showroom of the store was estimated to be the equivalent of:

an indoor lumber yard

a typical department store

a chemical processing plant

4000 gallons of gasoline

As the fire spread into the main showroom it:

transitioned to flashover

became ventilation limited

vented through the roof

caused the front windows to fail

Temperatures greater than 250F (120C) and oxygen levels below 12% were used to indicate:

fire growth rate

backdraft potential

untenable conditions

effectiveness of suppression operations

The simulation that was most consistent with the incident data collected during the investigation was identified as the:

most probable fire sequence

ignition scenario

fire cause determination

heat transfer model

The NIST Fire Dynamics Simulator (FDS) used to develop this simulation is a:

Fault Tree model

Failure Mode and Effects Analysis model

Heat Transfer Analysis model

Computational Fluid Dynamics model

For the simulation what materials were assumed to constitute the fuel load in the early stages of the fire?

Wood shelving

Foam and fabric

Internal wood components

Building and structural materials

The numerical modeling conducted for the Sofa Super Store fire provides:

quantitative data regarding the fire development.

a close approximation of the real world conditions in the fire.

a reasonable approximation of fire conditions during the fire.

data useful in the development of a fire cause scenario.

What impact did automatic sprinklers have on the tenability conditions in the main showroom in the simulation?

Conditions remained tenable throughout the simulation

Untenable at 1850 seconds

Untenable at 1600 seconds

Untenable at 1200 seconds
