Life-safety information is collected in two basic topic areas:

Answer 7

-Protection/Evacuation of occupants
-Protection of firefighters

Question 8

____ ____ ____ systems introduce thermostatically controlled air into the space through openings in the floor. The absence of overhead ducts or return air plenums allows an increase in ceiling heights. Return air passes through sidewall vents located adjacent to the HVAC system mechanical room.

Answer 8

Underfloor Air Distribution (UFAD) systems

Question 9

What situation is considered to need an extended length supply line?

Answer 9

If the length of the lay line would require more than one engine’s supply line

Question 10

The term ____ ____ ____ is used to describe the estimated uninterrupted quantity of water expressed in GPM that is needed to extinguish a well-established fire.

Answer 10

Required Fire Flow

Question 11

When calculating required fire flow for an offensive interior fire attack in a compartment or structure that is NO MORE THAN 50% involved, you can use the formula:

Answer 11

RFF in GPM =(Length x Width)/3 x % involvement

Question 12

_____ ___ is a formal, written agreement between jurisdictions that share a common boundary. It occurs whenever certain predetermined conditions occur.

Answer 12

Automatic Aid

Question 13

_____ ___ is a reciprocal agreement between two or more fire and emergency services organizations. Responses under this agreement are usually based on an on-request basis and do not guarantee a response from outside organizations.

Answer 13

Mutual Aid

Question 14

Some factors that will affect strategy and tactics with fires in Type I buildings constructed using protected steel frames or reinforced concrete include:

*6 answers

Answer 14

-High occupancy load and occupancy type
-Location of fire and number of floors involved
-Access/egress
-Ventilation difficulties
-Building safety features
-Resource needs

Question 15

Some factors that will affect strategy and tactics with fire in Type II buildings with metal framing concrete block walls include:

*6 answers

Answer 15

-Confirming the actual Type II construction
-Mixed occupancy types within the structure
-Likely areas of collapse due to construction features
-Potential large area and volume for fire growth
-Contents and processes
-Hoseline deployment and search tactics

Question 16

Some factors that will affect strategy and tactics with fire in Type III buildings, such as older churches and apartment buildings, include:

*4 answers

Answer 16

-Voids exist inside the wooden channels that roof and truss systems create that will allow fire spread unless proper fire-stopping is applied
-Renovations may have resulted in greater fire risk due to the creation of large voids above ceilings and below floors
-New construction materials may have been substituted for original materials during renovations. This results in reducing the load-carrying capacity of the supporting structural member
-The original use of the structure may have changed to one that requires a greater load-carrying capacity than that of the original design

Question 17

Some of the factors that will affect strategy and tactics with fires in Type IV (heavy-timber) structures, such as old factories and mills converted for residential use, include:

*5 answers

Answer 17

-Occupancy type and use (including any changes)
-Specific requirements for apparatus placement due to potential collapse of structure
-Lack of sufficient fire protection systems
-Conditions that require high fire flow/water supply
-Potential limited access

Question 18

Some of the factors that will affect strategy and tactics with fires in Type V (wood frame) structures, such as single-family dwellings and commercial buildings, include:

*5 answers

Answer 18

-High life hazard
-Structure contributes to the fire with early collapse potential
-Rapid fire spread due to construction and age of building
-Non-permitted remodeling and alterations to the building
-Open floor plans and void spaces that allow fire and smoke to travel throughout the structure

Question 19

There are FIVE categories of factory-built homes:

Answer 19

-Manufactured (most common type, almost completely prefabricated prior to delivery, least expensive)
-Modular (must comply with the same local building codes as site-built homes, permanent foundation)
-Panelized (assembled on-site from preconstructed panels made of foam insulation sandwiched between sheets of plywood)
-Precut (Custom cut and assembled on-site, includes pole houses, post and beam construction, log homes, A-frames, geodesic domes, etc)
-Hybrid Modular (includes elements of both modular design and panelized design)

Question 20

Conditions that make basement and cellar fires difficult to control include:

*5 answers

Answer 20

-Most basements have only one entry point that will funnel heat, fire, and smoke into the path of fire crews
-The ceiling above the basement is generally exposed and the low ceiling height (approx 8’) allows fire to rapidly spread upward
-Basements under balloon construction allow fire to spread up the insides of exterior walls to the roof
-Fires in crawl spaces have a lack of access
-Ventilation options are limited

Question 21

What is the difference between an attic and a cockloft?

Answer 21

Attics- usually in residential structures, large enough for a person to walk upright

Cockloft- space that is 2-3’ in height that is found over commercial building spaces, not designed for human habitation
